Overcoming Speech Impediment: Symptoms to Treatment

There are many causes and solutions for impaired speech

• Types and Symptoms
• Speech Therapy
• Building Confidence

Speech impediments are conditions that can cause a variety of symptoms, such as an inability to understand language or speak with a stable sense of tone, speed, or fluidity. There are many different types of speech impediments, and they can begin during childhood or develop during adulthood.

Common causes include physical trauma, neurological disorders, or anxiety. If you or your child is experiencing signs of a speech impediment, you need to know that these conditions can be diagnosed and treated with professional speech therapy.

This article will discuss what you can do if you are concerned about a speech impediment and what you can expect during your diagnostic process and therapy.

Types and Symptoms of Speech Impediment

People can have speech problems due to developmental conditions that begin to show symptoms during early childhood or as a result of conditions that may occur during adulthood. 

The main classifications of speech impairment are aphasia (difficulty understanding or producing the correct words or phrases) or dysarthria (difficulty enunciating words).

Often, speech problems can be part of neurological or neurodevelopmental disorders that also cause other symptoms, such as multiple sclerosis (MS) or autism spectrum disorder .

There are several different symptoms of speech impediments, and you may experience one or more.

Can Symptoms Worsen?

Most speech disorders cause persistent symptoms and can temporarily get worse when you are tired, anxious, or sick.

Symptoms of dysarthria can include:

• Slurred speech
• Slow speech
• Choppy speech
• Hesitant speech
• Inability to control the volume of your speech
• Shaking or tremulous speech pattern
• Inability to pronounce certain sounds

Symptoms of aphasia may involve:

• Speech apraxia (difficulty coordinating speech)
• Difficulty understanding the meaning of what other people are saying
• Inability to use the correct words
• Inability to repeat words or phases
• Speech that has an irregular rhythm

You can have one or more of these speech patterns as part of your speech impediment, and their combination and frequency will help determine the type and cause of your speech problem.

Causes of Speech Impediment

The conditions that cause speech impediments can include developmental problems that are present from birth, neurological diseases such as Parkinson’s disease , or sudden neurological events, such as a stroke .

Some people can also experience temporary speech impairment due to anxiety, intoxication, medication side effects, postictal state (the time immediately after a seizure), or a change of consciousness.

Speech Impairment in Children

Children can have speech disorders associated with neurodevelopmental problems, which can interfere with speech development. Some childhood neurological or neurodevelopmental disorders may cause a regression (backsliding) of speech skills.

Common causes of childhood speech impediments include:

• Autism spectrum disorder : A neurodevelopmental disorder that affects social and interactive development
• Cerebral palsy :  A congenital (from birth) disorder that affects learning and control of physical movement
• Hearing loss : Can affect the way children hear and imitate speech
• Rett syndrome : A genetic neurodevelopmental condition that causes regression of physical and social skills beginning during the early school-age years.
• Adrenoleukodystrophy : A genetic disorder that causes a decline in motor and cognitive skills beginning during early childhood
• Childhood metabolic disorders : A group of conditions that affects the way children break down nutrients, often resulting in toxic damage to organs
• Brain tumor : A growth that may damage areas of the brain, including those that control speech or language
• Encephalitis : Brain inflammation or infection that may affect the way regions in the brain function
• Hydrocephalus : Excess fluid within the skull, which may develop after brain surgery and can cause brain damage

Do Childhood Speech Disorders Persist?

Speech disorders during childhood can have persistent effects throughout life. Therapy can often help improve speech skills.

Speech Impairment in Adulthood

Adult speech disorders develop due to conditions that damage the speech areas of the brain.

Common causes of adult speech impairment include:

• Head trauma 
• Nerve injury
• Throat tumor
• Stroke 
• Parkinson’s disease 
• Essential tremor
• Brain tumor
• Brain infection

Additionally, people may develop changes in speech with advancing age, even without a specific neurological cause. This can happen due to presbyphonia , which is a change in the volume and control of speech due to declining hormone levels and reduced elasticity and movement of the vocal cords.

Do Speech Disorders Resolve on Their Own?

Children and adults who have persistent speech disorders are unlikely to experience spontaneous improvement without therapy and should seek professional attention.

Steps to Treating Speech Impediment 

If you or your child has a speech impediment, your healthcare providers will work to diagnose the type of speech impediment as well as the underlying condition that caused it. Defining the cause and type of speech impediment will help determine your prognosis and treatment plan.

Sometimes the cause is known before symptoms begin, as is the case with trauma or MS. Impaired speech may first be a symptom of a condition, such as a stroke that causes aphasia as the primary symptom.

The diagnosis will include a comprehensive medical history, physical examination, and a thorough evaluation of speech and language. Diagnostic testing is directed by the medical history and clinical evaluation.

Diagnostic testing may include:

• Brain imaging , such as brain computerized tomography (CT) or magnetic residence imaging (MRI), if there’s concern about a disease process in the brain
• Swallowing evaluation if there’s concern about dysfunction of the muscles in the throat
• Electromyography (EMG) and nerve conduction studies (aka nerve conduction velocity, or NCV) if there’s concern about nerve and muscle damage
• Blood tests, which can help in diagnosing inflammatory disorders or infections

Your diagnostic tests will help pinpoint the cause of your speech problem. Your treatment will include specific therapy to help improve your speech, as well as medication or other interventions to treat the underlying disorder.

For example, if you are diagnosed with MS, you would likely receive disease-modifying therapy to help prevent MS progression. And if you are diagnosed with a brain tumor, you may need surgery, chemotherapy, or radiation to treat the tumor.

Therapy to Address Speech Impediment

Therapy for speech impairment is interactive and directed by a specialist who is experienced in treating speech problems . Sometimes, children receive speech therapy as part of a specialized learning program at school.

The duration and frequency of your speech therapy program depend on the underlying cause of your impediment, your improvement, and approval from your health insurance.

If you or your child has a serious speech problem, you may qualify for speech therapy. Working with your therapist can help you build confidence, particularly as you begin to see improvement.

Exercises during speech therapy may include:

• Pronouncing individual sounds, such as la la la or da da da
• Practicing pronunciation of words that you have trouble pronouncing
• Adjusting the rate or volume of your speech
• Mouth exercises
• Practicing language skills by naming objects or repeating what the therapist is saying

These therapies are meant to help achieve more fluent and understandable speech as well as an increased comfort level with speech and language.

Building Confidence With Speech Problems 

Some types of speech impairment might not qualify for therapy. If you have speech difficulties due to anxiety or a social phobia or if you don’t have access to therapy, you might benefit from activities that can help you practice your speech. 

You might consider one or more of the following for you or your child:

• Joining a local theater group
• Volunteering in a school or community activity that involves interaction with the public
• Signing up for a class that requires a significant amount of class participation
• Joining a support group for people who have problems with speech

Activities that you do on your own to improve your confidence with speaking can be most beneficial when you are in a non-judgmental and safe space.

Many different types of speech problems can affect children and adults. Some of these are congenital (present from birth), while others are acquired due to health conditions, medication side effects, substances, or mood and anxiety disorders. Because there are so many different types of speech problems, seeking a medical diagnosis so you can get the right therapy for your specific disorder is crucial.

Speech and language problems: Ages 5 to 8

What to expect when

Mispronunciation, childhood apraxia of speech, when to seek help.

Children learn to talk at different speeds, so don't be surprised if your child isn't using the same vocabulary or expressions as playmates the same age. However, there are some general guidelines for typical speech and language development.

By age 5, your child should:

• Pronounce all the sounds of speech (though sounds like l , s , r , v , z , ch , sh , and th might still be tricky).
• Respond when asked, "What did you say?"
• Name letters and numbers.
• Use more than one verb in a sentence, such as, "I got my ball and played with Freddy."
• Tell short stories.
• Maintain a conversation.
• Tailor the way she talks to suit different listeners and places, like using shorter sentences with younger kids or a louder voice when playing outside.

By the end of first grade, your child should:

• Be easy to understand.
• Ask and answer wh questions – who, what, when, where, and why.
• Tell stories and talk about events in a logical order.
• Use varied, complete sentences.
• Use correct grammar most of the time.
• Initiate and maintain conversations, taking turns speaking.
• Give and follow directions with two and three steps.

By the end of second grade, your child also should:

• Be able to explain words and ideas.
• Use speech to inform, persuade, and engage with other people.
• Use more complex sentences.
• Take turns, stay on topic, and use eye contact during conversations.
• Give and follow directions with three and four steps.

Some children still have trouble getting ideas across or have other language difficulties that might affect their ability to learn important new skills, such as reading and writing .

Some children still have minor pronunciation problems at this age. Here are a few common ones you might hear:

• Your child might mix up words with multiple syllables, such as "manimal" for "animal," or "pasghetti" for "spaghetti."
• Some kids still struggle with a few tricky consonant sounds. Your child may say a w or a y for an l ("yeg" instead of "leg") or use w for r ("wabbit" instead of "rabbit") or substitute an f for a th ("baf" instead of "bath"). Diane Paul, director of clinical issues in speech-language pathology for the American Speech-Language-Hearing Association says, "Some of these sounds may not be speech errors at all, but just differences in an accent or dialect."

What you can do: When your child stumbles over long words, resist the urge to correct his speech. Just model the right pronunciation when it's your turn to talk. So instead of saying, "It's spaghetti, not pasghetti!" you can say, "Yes, we're having spaghetti for dinner."

These minor pronunciation problems may not be cause for concern, and most children can say all speech sounds by age 7. However, don't wait and hope your child will outgrow speech sound errors. A speech-language pathologist can help and the earlier, the better.

Your child may lisp or pronounce the s sound like a th , so that "My sister is seven" becomes "My thithter ith theven." Another common variation is to pronounce the z sound like a th , as in "thoo" for "zoo," and "eethee" for "easy."

What you can do: If your child still has a lisp by age 5, it's a good idea to make an appointment with a speech-language pathologist rather than continue waiting to see if your child outgrows it. The specialist will take a detailed history, check your child's mouth's structure and function, and get a speech and language sample to study. Often the problem can be resolved in a short time.

Also, make sure your child can breathe comfortably, and treat any allergy, cold, or sinus problems so your child can breathe through her nose with her lips together. An open-mouth breathing posture causes the tongue to lie flat and protrude. A stuffy nose is often the cause, so work on nose-blowing too.

Most people (adults and children alike) stutter from time to time, often when they're nervous or rushed. Examples of stuttering include:

• Repeating part of a word, as in, "W-w-w-where are you going?"
• Prolonging a sound, as in, "Ssssit down in the chair."
• Inserting interjections and having difficulty completing a sentence, as in, "I want to – um, um, um, you know, um – go outside."

Most kids outgrow stuttering before age 5. But some kids continue to stutter, and the reason why is unclear. Sometimes stuttering grows more severe over time, or it may vary quite a bit from day to day.

It's a good idea to make an appointment with an ASHA-certified speech-language pathologist Opens a new window if your child stutters regularly. The speech-language pathologist will do an evaluation to determine whether your child's stutter is likely to continue and can work with your child on therapy that will lessen the severity of stuttering.

A speech-language pathologist also can help if you see tension in your child's jaw or cheeks, or if he looks away, clenches his fist from tension, blinks repeatedly, grimaces, or stomps his feet in frustration trying to get the words out.

What you can do: Be patient. Resist the urge to finish your child's sentences or fill in words for him. Suggestions like "relax" or "slow down" aren't really helpful and can make your child feel even more pressure to get his words out.

Keep giving your child your attention. You may feel like looking away while your child tries to talk to give him time to calm down and make it easier to speak, but that might actually make him feel more rushed or even ashamed.

Childhood apraxia of speech (CAS) is a disorder of the nervous system that affects a child's ability to say sounds, syllables, and words. With CAS, the brain has trouble telling the lips, jaw, and tongue what to do in order to produce speech. A child with CAS knows what she wants to say but can't make the sounds come out correctly and consistently.

If your child has CAS she may do any of the following:

• She makes inconsistent pronunciation errors that aren't due to her not knowing how to say the sounds yet.
• She can understand language much better than she can speak.
• She has trouble imitating speech, but her imitated speech is clearer than her spontaneous speech.
• She appears to struggle when she tries to make sounds or coordinate her lips, tongue, and jaw to speak.
• She has more trouble saying longer words and phrases than shorter ones.
• She has more difficulty speaking when she's anxious.
• She's hard to understand, especially for someone who doesn't know her.
• Her speech sounds choppy or monotonous, or stresses the wrong syllable or word.

If your child shows signs of CAS, it's important to make an appointment with a speech-language pathologist as soon as possible. Most kids with CAS will need professional therapy to be able to speak clearly.

What you can do: Talk slowly but naturally. Let your child take her time when she tries to speak. Your child's speech-language pathologist may have more tips for you to try at home.

If you're worried about your child's speech and language development, give your child's doctor a call or make an appointment with an ASHA-certified speech-language pathologist Opens a new window . You may find you have nothing to worry about, but that's for a speech and language professional to determine. Also seek help if your child fits any of the following descriptions:

• Your child rarely asks questions or often lets adults do most of the talking, speaks only in short phrases and sentences, or seldom adds additional information to a story.
• Your child can't find the right word to express what he means – for instance, he may substitute words with related meanings ("cake" for "cupcake"), substitute words with similar sounds ("knob" for "knock"), or substitute visually related words ("clock" for "watch").
• Your child talks around words ("something we eat on" for table) or frequently says "thing" or "stuff" instead of using specific words.
• Your child uses long pauses between words and sentences.
• Your child drools when he mispronounces words or has difficulty eating or swallowing. (If this is the case, talk with his doctor.)
• Your child has trouble pronouncing many sounds or has trouble expressing himself. This could lead to reading, writing, and spelling difficulties if the problem isn't addressed.

In addition, if you have any concern that your child may have a speech or language delay due to a hearing loss, call his doctor, ask for a hearing evaluation by an audiologist at his school, or make an appointment with an ASHA-certified audiologist.

Speech sound disorders are a blanket description for a child’s difficulty in learning, articulating, or using the sounds/sound patterns of their language. These difficulties are usually clear when compared to the communication abilities of children within the same age group.

Speech developmental disorders may indicate challenges with motor speech. Here, a child experiences difficulty moving the muscles necessary for speech production. This child may also face reduced coordination when attempting to speak.

Speech sound disorders are recognized where speech patterns do not correspond with the movements/gestures made when speaking.  

Speech impairments are a common early childhood occurrence—an estimated 2% to 13% of children live with these difficulties. Children with these disorders may struggle with reading and writing. This can interfere with their expected academic performance. Speech sound disorders are often confused with language conditions such as specific language impairment (SLI).

This article will examine the distinguishing features of this disorder. It will also review factors responsible for speech challenges, and the different ways they can manifest. Lastly, we’ll cover different treatment methods that make managing this disorder possible.

Symptoms of Speech Sound Disorder

A speech sound disorder may manifest in different ways. This usually depends on the factors responsible for the challenge, or how extreme it is.

There are different patterns of error that may signal a speech sound disorder. These include:

• Removing a sound from a word
• Including a sound in a word
• Replacing hard to pronounce sounds with an unsuitable alternative
• Difficulty pronouncing the same sound in different words (e.g., "pig" and "kit")
• Repeating sounds or words
• Lengthening words
• Pauses while speaking
• Tension when producing sounds
• Head jerks during speech
• Blinking while speaking
• Shame while speaking
• Changes in voice pitch
• Running out of breath while speaking

It’s important to note that children develop at different rates. This can reflect in the ease and ability to produce sounds. But where children repeatedly make sounds or statements that are difficult to understand, this could indicate a speech disorder.

Diagnosis of Speech Sound Disorders

For a correct diagnosis, a speech-language pathologist can determine whether or not a child has a speech-sound disorder.

This determination may be made in line with the requirements of the DSM-5 diagnostic criteria . These guidelines require that:

• The child experience persistent difficulty with sound production (this affects communication and speech comprehension)
• Symptoms of the disorder appear early during the child’s development stages
• This disorder limits communication. It affects social interactions, academic achievements, and job performance.
• The disorder is not caused by other conditions like a congenital disorder or an acquired condition like hearing loss . Hereditary disorders are, however, exempted. 

Causes of Speech Sound Disorders

There is no known cause of speech sound disorders. However, several risk factors may increase the odds of developing a speech challenge. These include:

• Gender : Male children are more likely to develop a speech sound disorder
• Family history : Children with family members living with speech disorders may acquire a similar challenge.
• Socioeconomics : Being raised in a low socioeconomic environment may contribute to the development of speech and literacy challenges.
• Pre- and post-natal challenges : Difficulties faced during pregnancy such as maternal infections and stressors may worsen the chances of speech disorders in a child. Likewise, delivery complications, premature birth, and low-birth-weight could lead to speech disorders.
• Disabilities : Down syndrome, autism , and other disabilities may be linked to speech-sound disorders.
• Physical challenges : Children with a cleft lip may experience speech sound difficulties.
• Brain damage : These disorders may also be caused by an infection or trauma to a child’s brain . This is seen in conditions like cerebral palsy where the muscles affecting speech are injured.

Types of Speech Sound Disorders

By the time a child turns three, at least half of what they say should be properly understood. By ages four and five, most sounds should be pronounced correctly—although, exceptions may arise when pronouncing “l”, “s”,”r”,”v”, and other similar sounds. By seven or eight, harder sounds should be properly pronounced. 

A child with a speech sound disorder will continue to struggle to pronounce words, even past the expected age. Difficulty with speech patterns may signal one of the following speech sound disorders:

This refers to interruptions while speaking. Stuttering is the most common form of disfluency. It is recognized for recurring breaks in the free flow of speech. After the age of four, a child with disfluency will still repeat words or phrases while speaking. This child may include extra words or sounds when communicating—they may also make words longer by stressing syllables.

This disorder may cause tension while speaking. Other times, head jerking or blinking may be observed with disfluency. 

Children with this disorder often feel frustrated when speaking, it may also cause embarrassment during interactions. 

Articulation Disorder

When a child is unable to properly produce sounds, this may be caused by inexact placement, speed, pressure, or movement from the lips, tongue, or throat.  

This usually signals an articulation disorder, where sounds like “r”, “l”, or “s” may be changed. In these cases, a child’s communication may be understood by only close family members.

Phonological Disorder

A phonological disorder is present where a child is unable to make the speech sounds expected of their age. Here, mistakes may be made when producing sounds. Other times, sounds like consonants may be omitted when speaking.  

Voice Disorder

Where a child is observed to have a raspy voice, this may be an early sign of a voice disorder. Other indicators include voice breaks, a change in pitch, or an excessively loud or soft voice.  

Children that run out of breath while speaking may also live with this disorder. Likewise, children may sound very nasally, or can appear to have inadequate air coming out of their nose if they have a voice disorder.

Childhood apraxia of speech occurs when a child lacks the proper motor skills for sound production. Children with this condition will find it difficult to plan and produce movements in the tongue, lips, jaw, and palate required for speech.  

Treatment of Speech Sound Disorder

Parents of children with speech sound disorders may feel at a loss for the next steps to take. To avoid further strain to the child, it’s important to avoid showing excessive concern.

Instead, listening patiently to their needs, letting them speak without completing their sentences, and showing usual love and care can go a long way.

For professional assistance, a speech-language pathologist can assist with improving a child’s communication. These pathologists will typically use oral motor exercises to enhance speech.

These oral exercises may also include nonspeech oral exercises such as blowing, oral massages and brushing, cheek puffing, whistleblowing, etc.

Nonspeech oral exercises help to strengthen weak mouth muscles, and can help with learning the common ways of communicating.

Parents and children with speech sound disorders may also join support groups for information and assistance with the condition.

A Word From Verywell

It can be frustrating to witness the challenges in communication. But while it's understandable to long for typical communication from a child—the differences caused by speech disorders can be managed with the right care and supervision. Speaking to a speech therapist, and showing love o children with speech disorders can be important first steps in overcoming these conditions.

Speech Impediment: Definition, Causes, Types and Treatment

02 may speech impediment: definition, causes, types and treatment.

One of life’s joys as a parent is watching your kids grow and change. You see them learn new things, meet new friends, and explore the world around them. But sometimes, you also witness them struggle – like when they have their first fight with a friend or don’t do as well as they wanted to on a test. And while it’s never easy to see your child suffer, one of the hardest things to watch is when your child has difficulty communicating. If your child has a speech impediment, you know that feeling all too well. It can be frustrating and heartbreaking to see your little one struggling to be understood. But take heart – you’re not alone. Many children have difficulties with speech, and with the right pediatric speech therapist in Chicago , your child can learn to overcome their impediment. This blog post will define a speech impediment, discuss some of the most common types and causes, and provide information on treatment options.

What is a speech impediment?

A speech impediment is a condition that affects a person’s ability to produce sound correctly. The term can refer to any difficulties that impede a person’s speech, from mild sound errors to severe problems with articulation. All individuals with speech impediments have difficulty producing certain sounds, depending on one sound. Some people may only have trouble with one sound, while others may have difficulty producing multiple sounds.

What causes speech impediments?

Some people are born with speech impediments, while others develop them later in life. There are many different causes of speech impediment, as you will see below.

1. Congenital defects Congenital defects are abnormalities that are present at birth. They can affect any part of the body, including the mouth and vocal cords. In some cases, congenital defects can cause problems with the tongue moving or the formation of teeth. Many different types of congenital defects can cause a speech impediment, including : Cleft lip and palate is a condition where there is an opening in the lip and/or roof of the mouth. This opening can cause problems with the way the mouth forms words, as well as with eating and drinking. Cleft lip and palate can also cause hearing problems. Vocal cord paralysis is a condition where the vocal cords are unable to move correctly. This can make it difficult to produce sound, as well as to breathe properly. Tongue-tie is a condition where the tongue is tethered to the floor of the mouth. This can make it difficult to move the tongue and can cause problems with eating, drinking, and speaking.

2. Neurological disorders Neurological disorders are conditions that affect the nervous system. These disorders can cause problems with the way the brain sends signals to the muscles, which can lead to difficulties with movement and speech. Some of the more common neurological disorders include: Cerebral palsy is a condition that affects movement and muscle coordination. It is caused by damage to the brain, usually before or during birth. Cerebral palsy can cause problems with the way a person walks, talks, and eats. Multiple sclerosis is a disease of the nervous system that causes the immune system to attack the nerves. This can lead to problems with muscle control and vision, hearing, and speech.

3. Hearing loss Hearing loss can be caused by many different things, including exposure to loud noise, certain medications, and aging. Hearing loss can make it difficult to understand what other people are saying, which can lead to problems with speech. There are many different types of hearing loss, and the severity can vary from person to person. Some people with hearing loss may only have trouble hearing certain sounds, while others may not be able to hear anything at all. Hearing loss can be temporary or permanent. Temporary hearing loss can be caused by things like earwax buildup or infection. Permanent hearing loss can be caused by things like damage to the inner ear or a genetic disorder.

4. Language disorders Language disorders are conditions that affect a person’s ability to understand or use language. These disorders can make it difficult to produce or comprehend speech. Some of the more common language disorders include dyslexia and aphasia.

5. Emotional disorders Emotional disorders are conditions that affect a person’s emotions or mood. These disorders can cause problems with speech due to anxiety or stress. Some of the more common emotional disorders include anxiety disorders and depression. lip

Types of speech disorder

There are many different types of speech disorders, and the symptoms can vary from person to person. Some of the more common types of speech disorders include:

1. Articulation disorder An articulation disorder is a problem with the way the mouth, teeth, or tongue move to make sounds. This can make it difficult to produce certain sounds correctly. People with articulation disorders may have trouble saying certain words correctly, or they may leave out parts of words when they speak.

2. Fluency disorder A fluency disorder is a problem with the flow of speech. People with fluency disorders may have trouble putting their thoughts into words, and they may stutter when they speak. Stuttering is a type of fluency disorder that is characterized by pauses, repetitions, or prolongations of sounds.

3. Resonance disorder A resonance disorder is a problem with the way sound resonates in the mouth and throat. This can make it difficult to produce certain sounds correctly. People with resonance disorders may have trouble producing vowel sounds, or they may speak with a nasal tone.

4. Voice disorder A voice disorder is a problem with the way the voice sounds. This can be caused by things like vocal cord damage or misuse of the voice. People with voice disorders may have trouble speaking loudly or speaking in a hoarse or breathy voice.

Treatment of speech impediments

There are many different treatments for speech disorders, and the best treatment will depend on the individual and the cause of the disorder. Some of the more common treatments include:

1. Speech therapy Speech therapy is a type of treatment that helps people with speech disorders improve their abilities. Speech therapists can help people with articulation disorders learn to produce sounds correctly, people with fluency disorders reduce their stuttering, and people with resonance disorders improve their vowel production.

2. Surgery Surgery can be used to correct some anatomical defects that cause speech disorders. For example, surgery can be used to correct cleft lip and palate, vocal cord paralysis, and tongue tie.

3. Medication Medication can be used to treat some neurological disorders that cause speech disorders. For example, medication can be used to treat conditions like cerebral palsy and multiple sclerosis.

4. Hearing aids Hearing aids can be used to treat hearing loss that causes speech disorders. Hearing aids amplify sound so that people with hearing loss can better understand what other people are saying.

5. Communication devices Communication devices can be used to help people with language disorders or severe speech disorders communicate. These devices can include things like picture boards and computer software that helps people generate speech.

6. Counseling Counseling can be used to treat emotional disorders that cause speech disorders. Counseling can help people manage their anxiety and stress and learn coping mechanisms to deal with their disorders.

7. Alternative treatments There are many different alternative treatments for speech disorders. Some of these treatments include acupuncture, aromatherapy, and massage therapy. It is important to speak with a doctor before starting any alternative treatment.

Speech disorders can cause a variety of problems for people, ranging from difficulty understanding what other people are saying to difficulty producing speech. There are many different causes of speech disorders, and the best treatment will depend on the individual and the cause of the disorder.

What Is a Speech Impediment?

Types of speech disorders, speech impediment causes, how to fix a speech impediment, making a difference in speech disorders.

Communication is a cornerstone of human relationships. When an individual struggles to verbalize information, thoughts, and feelings, it can cause major barriers in personal, learning, and business interactions.

Speech impediments, or speech disorders, can lead to feelings of insecurity and frustration. They can also cause worry for family members and friends who don’t know how to help their loved ones express themselves.

Fortunately, there are a number of ways that speech disorders can be treated, and in many cases, cured. Health professionals in fields including speech-language pathology and audiology can work with patients to overcome communication disorders, and individuals and families can learn techniques to help.

Commonly referred to as a speech disorder, a speech impediment is a condition that impacts an individual’s ability to speak fluently, correctly, or with clear resonance or tone. Individuals with speech disorders have problems creating understandable sounds or forming words, leading to communication difficulties.

Some 7.7% of U.S. children — or 1 in 12 youths between the ages of 3 and 17 — have speech, voice, language, or swallowing disorders, according to the National Institute on Deafness and Other Communication Disorders (NIDCD). About 70 million people worldwide, including some 3 million Americans, experience stuttering difficulties, according to the Stuttering Foundation.

Common signs of a speech disorder

There are several symptoms and indicators that can point to a speech disorder.

• Unintelligible speech — A speech disorder may be present when others have difficulty understanding a person’s verbalizations.
• Omitted sounds — This symptom can include the omission of part of a word, such as saying “bo” instead of “boat,” and may include omission of consonants or syllables.
• Added sounds — This can involve adding extra sounds in a word, such as “buhlack” instead of “black,” or repeating sounds like “b-b-b-ball.”
• Substituted sounds — When sounds are substituted or distorted, such as saying “wabbit” instead of “rabbit,” it may indicate a speech disorder.
• Use of gestures — When individuals use gestures to communicate instead of words, a speech impediment may be the cause.
• Inappropriate pitch — This symptom is characterized by speaking with a strange pitch or volume.

In children, signs might also include a lack of babbling or making limited sounds. Symptoms may also include the incorrect use of specific sounds in words, according to the American Speech-Language-Hearing Association (ASHA). This may include the sounds p, m, b, w, and h among children aged 1-2, and k, f, g, d, n, and t for children aged 2-3.

Categories of Speech Impediments

Speech impediments can range from speech sound disorders (articulation and phonological disorders) to voice disorders. Speech sound disorders may be organic — resulting from a motor or sensory cause — or may be functional with no known cause. Voice disorders deal with physical problems that limit speech. The main categories of speech impediments include the following:

Fluency disorders occur when a patient has trouble with speech timing or rhythms. This can lead to hesitations, repetitions, or prolonged sounds. Fluency disorders include stuttering (repetition of sounds) or   (rapid or irregular rate of speech).

Resonance disorders are related to voice quality that is impacted by the shape of the nose, throat, and/or mouth. Examples of resonance disorders include hyponasality and cul-de-sac resonance.

Articulation disorders occur when a patient has difficulty producing speech sounds. These disorders may stem from physical or anatomical limitations such as muscular, neuromuscular, or skeletal support. Examples of articulation speech impairments include sound omissions, substitutions, and distortions.

Phonological disorders result in the misuse of certain speech sounds to form words. Conditions include fronting, stopping, and the omission of final consonants.

Voice disorders are the result of problems in the larynx that harm the quality or use of an individual’s voice. This can impact pitch, resonance, and loudness.

Impact of Speech Disorders

Some speech disorders have little impact on socialization and daily activities, but other conditions can make some tasks difficult for individuals. Following are a few of the impacts of speech impediments.

• Poor communication — Children may be unable to participate in certain learning activities, such as answering questions or reading out loud, due to communication difficulties. Adults may avoid work or social activities such as giving speeches or attending parties.
• Mental health and confidence — Speech disorders may cause children or adults to feel different from peers, leading to a lack of self-confidence and, potentially, self-isolation.

Resources on Speech Disorders

The following resources may help those who are seeking more information about speech impediments.

Health Information : Information and statistics on common voice and speech disorders from the NIDCD

Speech Disorders : Information on childhood speech disorders from Cincinnati Children’s Hospital Medical Center

Speech, Language, and Swallowing : Resources about speech and language development from the ASHA

Children and adults can suffer from a variety of speech impairments that may have mild to severe impacts on their ability to communicate. The following 10 conditions are examples of specific types of speech disorders and voice disorders.

1. Stuttering

This condition is one of the most common speech disorders. Stuttering is the repetition of syllables or words, interruptions in speech, or prolonged use of a sound.

This organic speech disorder is a result of damage to the neural pathways that connect the brain to speech-producing muscles. This results in a person knowing what they want to say, but being unable to speak the words.

This consists of the lost ability to speak, understand, or write languages. It is common in stroke, brain tumor, or traumatic brain injury patients.

4. Dysarthria

This condition is an organic speech sound disorder that involves difficulty expressing certain noises. This may involve slurring, or poor pronunciation, and rhythm differences related to nerve or brain disorders.

The condition of lisping is the replacing of sounds in words, including “th” for “s.” Lisping is a functional speech impediment.

6. Hyponasality

This condition is a resonance disorder related to limited sound coming through the nose, causing a “stopped up” quality to speech.

7. Cul-de-sac resonance

This speech disorder is the result of blockage in the mouth, throat, or nose that results in quiet or muffled speech.

8. Orofacial myofunctional disorders

These conditions involve abnormal patterns of mouth and face movement. Conditions include tongue thrusting (fronting), where individuals push out their tongue while eating or talking.

9. Spasmodic Dysphonia

This condition is a voice disorder in which spasms in the vocal cords produce speech that is hoarse, strained, or jittery.

10. Other voice disorders

These conditions can include having a voice that sounds breathy, hoarse, or scratchy. Some disorders deal with vocal folds closing when they should open (paradoxical vocal fold movement) or the presence of polyps or nodules in the vocal folds.

Speech Disorders vs. Language Disorders

Speech disorders deal with difficulty in creating sounds due to articulation, fluency, phonology, and voice problems. These problems are typically related to physical, motor, sensory, neurological, or mental health issues.

Language disorders, on the other hand, occur when individuals have difficulty communicating the meaning of what they want to express. Common in children, these disorders may result in low vocabulary and difficulty saying complex sentences. Such a disorder may reflect difficulty in comprehending school lessons or adopting new words, or it may be related to a learning disability such as dyslexia. Language disorders can also involve receptive language difficulties, where individuals have trouble understanding the messages that others are trying to convey.  

Resources on Types of Speech Disorders

The following resources may provide additional information on the types of speech impediments.

Stuttering Facts: Information on stuttering indications and causes from the Stuttering Foundation

Speech disorders may be caused by a variety of factors related to physical features, neurological ailments, or mental health conditions. In children, they may be related to developmental issues or unknown causes and may go away naturally over time.

Physical and neurological issues. Speech impediment causes related to physical characteristics may include:

• Brain damage
• Nervous system damage
• Respiratory system damage
• Hearing difficulties
• Cancerous or noncancerous growths
• Muscle and bone problems such as dental issues or cleft palate

Mental health issues. Some speech disorders are related to clinical conditions such as:

• Autism spectrum disorder
• Down syndrome or other genetic syndromes
• Cerebral palsy or other neurological disorders
• Multiple sclerosis

Some speech impairments may also have to do with family history, such as when parents or siblings have experienced language or speech difficulties. Other causes may include premature birth, pregnancy complications, or delivery difficulties. Voice overuse and chronic coughs can also cause speech issues.

The most common way that speech disorders are treated involves seeking professional help. If patients and families feel that symptoms warrant therapy, health professionals can help determine how to fix a speech impediment. Early treatment is best to curb speech disorders, but impairments can also be treated later in life.

Professionals in the speech therapy field include speech-language pathologists (SLPs) . These practitioners assess, diagnose, and treat communication disorders including speech, language, social, cognitive, and swallowing disorders in both adults and children. They may have an SLP assistant to help with diagnostic and therapy activities.

Speech-language pathologists may also share a practice with audiologists and audiology assistants. Audiologists help identify and treat hearing, balance, and other auditory disorders.

How Are Speech Disorders Diagnosed?

Typically, a pediatrician, social worker, teacher, or other concerned party will recognize the symptoms of a speech disorder in children. These individuals, who frequently deal with speech and language conditions and are more familiar with symptoms, will recommend that parents have their child evaluated. Adults who struggle with speech problems may seek direct guidance from a physician or speech evaluation specialist.

When evaluating a patient for a potential speech impediment, a physician will:

• Conduct hearing and vision tests
• Evaluate patient records
• Observe patient symptoms

A speech-language pathologist will conduct an initial screening that might include:

• An evaluation of speech sounds in words and sentences
• An evaluation of oral motor function
• An orofacial examination
• An assessment of language comprehension

The initial screening might result in no action if speech symptoms are determined to be developmentally appropriate. If a disorder is suspected, the initial screening might result in a referral for a comprehensive speech sound assessment, comprehensive language assessment, audiology evaluation, or other medical services.

Initial assessments and more in-depth screenings might occur in a private speech therapy practice, rehabilitation center, school, childcare program, or early intervention center. For older adults, skilled nursing centers and nursing homes may assess patients for speech, hearing, and language disorders.

How Are Speech Impediments Treated?

Once an evaluation determines precisely what type of speech sound disorder is present, patients can begin treatment. Speech-language pathologists use a combination of therapy, exercise, and assistive devices to treat speech disorders.

Speech therapy might focus on motor production (articulation) or linguistic (phonological or language-based) elements of speech, according to ASHA. There are various types of speech therapy available to patients.

Contextual Utilization  — This therapeutic approach teaches methods for producing sounds consistently in different syllable-based contexts, such as phonemic or phonetic contexts. These methods are helpful for patients who produce sounds inconsistently.

Phonological Contrast — This approach focuses on improving speech through emphasis of phonemic contrasts that serve to differentiate words. Examples might include minimal opposition words (pot vs. spot) or maximal oppositions (mall vs. call). These therapy methods can help patients who use phonological error patterns.

Distinctive Feature — In this category of therapy, SLPs focus on elements that are missing in speech, such as articulation or nasality. This helps patients who substitute sounds by teaching them to distinguish target sounds from substituted sounds.

Core Vocabulary — This therapeutic approach involves practicing whole words that are commonly used in a specific patient’s communications. It is effective for patients with inconsistent sound production.

Metaphon — In this type of therapy, patients are taught to identify phonological language structures. The technique focuses on contrasting sound elements, such as loud vs. quiet, and helps patients with unintelligible speech issues.

Oral-Motor — This approach uses non-speech exercises to supplement sound therapies. This helps patients gain oral-motor strength and control to improve articulation.

Other methods professionals may use to help fix speech impediments include relaxation, breathing, muscle strengthening, and voice exercises. They may also recommend assistive devices, which may include:

• Radio transmission systems
• Personal amplifiers
• Picture boards
• Touch screens
• Text displays
• Speech-generating devices
• Hearing aids
• Cochlear implants

Speech Disorder Tips for Families

For parents who are concerned that their child might have a speech disorder — or who want to prevent the development of a disorder — there are a number of activities that can help. The following are tasks that parents can engage in on a regular basis to develop literacy and speech skills.

• Introducing new vocabulary words
• Reading picture and story books with various sounds and patterns
• Talking to children about objects and events
• Answering children’s questions during routine activities
• Encouraging drawing and scribbling
• Pointing to words while reading books
• Pointing out words and sentences in objects and signs

Parents can take the following steps to make sure that potential speech impediments are identified early on.

• Discussing concerns with physicians
• Asking for hearing, vision, and speech screenings from doctors
• Requesting special education assessments from school officials
• Requesting a referral to a speech-language pathologist, audiologist, or other specialist

When a child is engaged in speech therapy, speech-language pathologists will typically establish collaborative relationships with families, sharing information and encouraging parents to participate in therapy decisions and practices.

SLPs will work with patients and their families to set goals for therapy outcomes. In addition to therapy sessions, they may develop activities and exercises for families to work on at home. It is important that caregivers are encouraging and patient with children during therapy.  

Resources for Parents on How to Fix a Speech Impediment

If identified during childhood, speech disorders can be corrected efficiently, giving children greater communication opportunities. If left untreated, speech impediments can cause a variety of problems in adulthood, and may be more difficult to diagnose and treat.

Parents, teachers, doctors, speech and language professionals, and other concerned parties all have unique responsibilities in recognizing and treating speech disorders. Through professional therapy, family engagement, positive encouragement and a strong support network, individuals with speech impediments can overcome their challenges and develop essential communication skills.

Stuttering is a speech condition that disrupts the normal flow of speech. Fluency means having an easy and smooth flow and rhythm when speaking. With stuttering, the interruptions in flow happen often and cause problems for the speaker. Other names for stuttering are stammering and childhood-onset fluency disorder.

People who stutter know what they want to say, but they have a hard time saying it. For example, they may repeat or stretch out a word, a syllable, or a consonant or vowel sound. Or they may pause during speech because they've reached a word or sound that's hard to get out.

Stuttering is common among young children as a usual part of learning to speak. Some young children may stutter when their speech and language abilities aren't developed enough to keep up with what they want to say. Most children outgrow this type of stuttering, called developmental stuttering.

But sometimes stuttering is a long-term condition that remains into adulthood. This type of stuttering can affect self-esteem and communicating with other people.

Children and adults who stutter may be helped by treatments such as speech therapy, electronic devices to improve speech fluency or a form of mental health therapy called cognitive behavioral therapy.

Stuttering symptoms may include:

• Having a hard time starting a word, phrase or sentence.
• Stretching out a word or sounds within a word.
• Repeating a sound, syllable or word.
• Brief silence for certain syllables or words, or pausing before or within a word.
• Adding extra words such as "um" if expecting to have problems moving to the next word.
• A lot of tension, tightness or movement of the face or upper body when saying a word.
• Anxiety about talking.
• Not being able to communicate well with others.

These actions may happen when stuttering:

• Rapid eye blinks.
• Trembling of the lips or jaw.
• Unusual face movements, sometimes called facial tics.
• Head nodding.
• Tightening of fists.

Stuttering may be worse when the person is excited, tired or under stress, or when feeling self-conscious, hurried or pressured. Situations such as speaking in front of a group or talking on the phone can be especially hard for people who stutter.

But most people who stutter can speak without stuttering when they talk to themselves and when they sing or speak along with someone else.

When to see a doctor or speech-language pathologist

It's common for children between the ages of 2 and 5 years to go through periods when they may stutter. For most children, this is part of learning to speak, and it gets better on its own. But stuttering that continues may need treatment to improve speech fluency.

Call your healthcare professional for a referral to a specialist in speech and language called a speech-language pathologist. Or you can contact the speech-language pathologist directly for an appointment. Ask for help if stuttering:

• Lasts more than six months.
• Happens along with other speech or language problems.
• Happens more often or continues as the child grows older.
• Includes muscle tightening or physically struggling when trying to speak.
• Affects the ability to effectively communicate at school or work or in social situations.
• Causes anxiety or emotional problems, such as fear of or not taking part in situations that require speaking.
• Begins as an adult.

Researchers continue to study the underlying causes of developmental stuttering. A combination of factors may be involved.

Developmental stuttering

Stuttering that happens in children while they're learning to speak is called developmental stuttering. Possible causes of developmental stuttering include:

• Problems with speech motor control. Some evidence shows that problems in speech motor control, such as timing, sensory and motor coordination, may be involved.
• Genetics. Stuttering tends to run in families. It appears that stuttering can happen from changes in genes passed down from parents to children.

Stuttering that happens from other causes

Speech fluency can be disrupted from causes other than developmental stuttering.

• Neurogenic stuttering. A stroke, traumatic brain injury or other brain disorders can cause speech that is slow or has pauses or repeated sounds.
• Emotional distress. Speech fluency can be disrupted during times of emotional distress. Speakers who usually do not stutter may experience problems with fluency when they are nervous or feel pressured. These situations also may cause speakers who stutter to have greater problems with fluency.
• Psychogenic stuttering. Speech difficulties that appear after an emotional trauma are uncommon and not the same as developmental stuttering.

Risk factors

Males are much more likely to stutter than females are. Things that raise the risk of stuttering include:

• Having a childhood developmental condition. Children who have developmental conditions, such as attention-deficit/hyperactivity disorder, autism or developmental delays, may be more likely to stutter. This is true for children with other speech problems too.
• Having relatives who stutter. Stuttering tends to run in families.
• Stress. Stress in the family and other types of stress or pressure can worsen existing stuttering.

Complications

Stuttering can lead to:

• Problems communicating with others.
• Not speaking or staying away from situations that require speaking.
• Not taking part in social, school or work activities and opportunities for success.
• Being bullied or teased.

Common Speech Impediments: Causes, Symptoms, Treatment, And Support

Speech impediments include a variety of both language and speech disorders, some of which can be addressed through  online speech therapy  with speech-language pathologists. They can arise because of heredity and genetics, developmental delays, or even damage to Broca’s area—the part of the brain that’s involved in language skills and speech skills. They may also be linked to other conditions like autism spectrum disorder, cerebral palsy, dyslexia, or even hearing loss. It depends on the type and the cause, but most speech impediments and speech impairments can be treated through speech therapy.

That said, recognizing when a speech impediment may be present can help you get yourself or your child the treatment and support they may need for improved academic and/or social functioning and self-confidence.

Common symptoms of a speech impediment

There are many different types of speech impediments a person can have, so the symptoms can vary. That said, those listed below are common symptoms that could be initial indicators that you or your child may be experiencing speech problems or challenges:

• Elongating words
• Quiet or muffled speech
• Blinking frequently
• Distorted sounds while talking
• Frequent changes in pitch
• Poor voice quality
• Visible frustration when trying to communicate
• Overall difficulty communicating and expressing thoughts and ideas
• Inability to repeat words
• Inability to pronounce words the same way twice
• A phobia of speaking in public
• Speaking slowly and carefully
• Speech delay
• Frequent pauses when talking
• Limited vocabulary over several years, delayed language development

Some speech and language disorders are consistent with underlying mental health conditions such as autism. You can visit licensed health professionals or speech therapists to receive an accurate diagnosis and find out how to treat a speech impediment or language disorder, and its underlying cause, if applicable.

Key categories of speech impediments

Speech impediments or communication disorders can take many forms, from speech sound disorders to voice-related disorders. While speech sound disorders mostly result from sensory or motor causes, voice-related disorders deal with physical problems regarding speech. Read on for a list of some of the most common categories of speech impediments.

Voice disorders

Voice disorders  primarily arise due to issues regarding the health and structure of the larynx or the voice box. They can impact pitch, resonance, volume, and voice quality. Symptoms of a voice disorder may include having a hoarse, quivering, strained, choppy, or weak and whispery voice, which can make it difficult to produce speech sounds.

The root cause of these disorders can be either organic, like alterations to respiratory, laryngeal, or vocal tract mechanisms, or functional, like improper use of the voice. Some risk factors that may contribute to vocal health challenges include allergies, psychological stress, age, excessive alcohol or drug use, screaming, scarring from neck surgery, or even gastroesophageal reflux disease (GERD). Examples of voice disorders include laryngitis, vocal cord paralysis/weakness, polyps or nodes present on the vocal cords, leukoplakia, or muscle tension dysphonia.

Fluency disorders

A person may be diagnosed with a fluency disorder if they have trouble with speech timing and rhythm which makes it difficult to create a normal speech pattern. These disorders are characterized by interruptions in the typical flow of speaking, including abnormal repetitions, hesitation, and prolongations. Their cause is unknown, but it may be genetic. Symptoms can also be exacerbated by stress and anxiety. Stuttering is the most common example of fluency disorders. 

Symptoms of a fluency disorder may include dragging out syllables, speaking breathlessly, repetition of words, speaking slowly, and being tense while speaking. Secondary symptoms may include fidgeting, mumbling, saying “um” or “uh” often, not using certain problematic words, rearranging words in sentences, and anxiety around speaking. Treatment options vary depending on the specific disorder. With stuttering, for example, slowing down, practicing, using speech monitors, attending speech therapy, and receiving cognitive behavioral therapy (CBT) are all potential treatment options.

Articulation disorders and phonological disorders

Articulation and phonological disorders are two types of speech disorders classified as speech sound disorders that may impact communication. An articulation disorder includes speech that commonly exhibits errors such as substitution, omission, distortion, and/or addition (SODA). Although the actual causes of articulation disorders aren’t well understood, contributing factors may include brain injuries, a cleft palate/cleft lip, or nerve damage. Phonological disorders typically involve producing sounds correctly but using them in the wrong place and are more predictable than articulation errors. There may also be a genetic factor that contributes to both disorders and other families may be impacted as well. A licensed speech-language pathologist (SLP) can determine if an individual may have an articulation disorder or a phonological disorder. Ongoing speech therapy is typically the recommended treatment method.

Speech impediments versus language impairments

A speech impediment is typically characterized by difficulty creating sound due to factors like fluency disorders or other voice problems. These disorders may arise from underlying mental health issues, neurological problems, or physical factors or conditions impacting speech muscles.

Language impairments, on the other hand, are more about difficulty processing, reading, and writing and can be connected to an issue processing receptive language. They’re common in children, especially when they first start school. Language impairments relate to meaning, whereas speech impediments relate to sound. It’s also very common for a language impairment disorder to present alongside a learning disability like dyslexia.

Examples of speech impediments

Below is a brief overview of a few of the most common speech disorders and speech impediments, along with symptoms and potential treatment options.

Apraxia of speech is a speech sound disorder that affects the pathways of the brain. It’s characterized by a person having difficulty expressing their thoughts accurately and consistently. It involves the brain being able to form the words and knowing exactly what to say, but the person then being unable to properly execute the required speech movements to deliver accurate sounds. In mild cases, a person will only have small limitations in their ability to form speech sounds. In severe cases, alternate communication methods may need to be used.

An SLP is the type of provider who can diagnose apraxia. To diagnose speech disorders, including both childhood apraxia (sometimes called verbal apraxia) and acquired apraxia, they may ask the individual to perform simple speech tasks like repeating a particular word several times or repeating a list of words that increase in length. Apraxia generally needs to be monitored by both parents and an SLP over time for an accurate diagnosis to be possible.

There are various treatment options for apraxia, the most common being one-on-one meetings with a speech pathologist. They’ll likely help you or your child build helpful strategies and skills to help strengthen problem areas and communicate more clearly. Some other treatment methods include improving speech intelligibility or using alternate forms of communication, like electronic speech or manual signs and gestures.

The National Institute on Deafness and Other Communication Disorders describes aphasia as a communication disorder that results in a person’s inability to speak, write, and/or understand language. Like other communication disorders, it may occur because of damage to the portions of the brain that are involved in language, which is common in those who have experienced a stroke. It may also come on gradually in those who have a tumor or a progressive neurological disease like Alzheimer’s. Symptoms may include saying or writing sentences that don’t make sense, a reduction in a person’s ability to understand a conversation, and substituting certain sounds and words for others.

Since this disorder is usually caused by damage to parts of the brain, it will typically first be recognized in an MRI or CT scan that can confirm the presence of a brain injury. The extent and type of aphasia can generally only be determined by observing the affected part of the brain and determining how extensively it has been damaged, which is often done with the help of an SLP.

Treatment options for aphasia can be restorative (aimed at restoring impaired function) or compensatory (aimed at compensating for deficits).

Dysarthria 

Dysarthria is usually caused by brain damage or facial paralysis that affects the muscles of the jaw, tongue, or throat, which may result in deficits in a person’s speech. It may also be caused by other conditions like Lou Gehrig’s disease, Parkinson’s, or a stroke. It’s considered a nervous system disorder, subclassified as a motor speech disorder. It’s commonly seen in those who already have other speech disorders, such as aphasia or apraxia. Symptoms of dysarthria include slurred speech, speaking too slowly, speaking too quickly, speaking very softly, being unable to move one’s lips or jaw, and having monotonous speech.

Dysarthria can be diagnosed by an expert in speech-language pathology through an exam and tests like MRI, CT, electromyography, or the Denver articulation screening examination. Treatment depends upon the severity and rate of progression of the disorder. Some potential examples include tactics like slowing down while talking, doing exercises to help strengthen jaw muscles, moving the lips and tongue more, and learning strategies for speaking more loudly. Hand gestures and speech machines may also help. 

The importance of treatment

It is important to treat speech disorders; the consequences of an untreated speech or language impediment can vary widely depending on the type, symptoms, and severity, as well as the age and life situation of the individual. In general, it’s usually helpful to seek professional advice on treating speech disorders as soon as you notice or suspect an impediment present in yours or your child’s speech. Especially for moderate to severe cases, some potential effects of leaving these common speech disorders untreated can include:

• Poor academic performance/dropping out of school
• Decrease in quality of life
• Social anxiety and an inability to connect with people
• Damaged relationships
• Social isolation
• Hospitalization

Seeking professional support

Meeting with an SLP is usually the recommended first step for someone who believes they or their child may have a speech impediment. If you have a teenager with dyslexia, there are  resources for dyslexic teens  that can give supportive information about the condition. Healthcare providers may also provide helpful insights and ask about your family members’ history when it comes to speech and language-related issues as they can be hereditary. While these professionals can help with the physical aspects of a variety of speech and language impediments, you or your child may also benefit from emotional support in relation to the mental health effects of having an impediment. A therapist may be able to provide this type of guidance. If your child is experiencing a speech impediment, a counselor may be able to work with them to process their feelings of frustration and learn healthy coping mechanisms for stress. They can help you manage the same feelings if you receive a speech or language impediment diagnosis, or may be able to support you in your journey of parenting a child with a speech or language impediment diagnosis.

In addition to support at home, teenagers with a diagnosed speech impairment or impediment can receive special education services at school. The Centers for Disease Control notes that under the Individuals with Disabilities Act (IDEA) and Section 504, schools must provide support and accommodations for students with speech disorders. For some children, support groups can provide outlets for social connections and advice for coping. 

Meeting with a therapist in person is an option if there are providers in your area. That said, many people find it less intimidating or more comfortable to meet with a therapist virtually. For example, a teen who is experiencing a speech or language impediment may feel better interacting with a counselor through the online chat feature that virtual therapy platforms like TeenCounseling provide. It may allow them to express themselves more clearly than they could face-to-face or over the phone. Parents who need support in caring for a child with a speech or language impediment may find the availability and convenience of meeting with a therapist through an online therapy service like BetterHelp to be most beneficial. Research suggests that online and in-person therapy offer similar benefits for a variety of conditions, so you can choose the format that’s best for you.

Counselor reviews

See below for reviews of TeenCounseling therapists written by parents who sought help for their children through this service. 

“Kathleen has been good for my daughter to talk to. I am thankful for her to give my daughter someone else's perspective other than her parents. Thank you.”

“I love Ms. Jones. She doesn’t over-talk or judge you. She gives really good advice and if you're confused she knows how to break it down or explain whatever it is so you can understand. If you need to talk about anything, she’s always an open ear and responds quickly. Not only does she give you points from others' perspectives but she steps into yours so she can understand why certain things are the way they are. In my first session, I was nervous and I think she could tell. She’ll crack a joke every now and then to make me feel more comfortable. She’s just such a bundle of joy and a good counselor to have.”

Speech and language impediments can vary widely in terms of types, causes, symptoms, and severity. These are diagnosed by professionals in the field of speech and language pathology or by a medical doctor. A therapist can provide emotional support for those who are having difficulty coping with their own or their child’s diagnosis or other related challenges. 

What are the 3 speech impediments?

Speech impediments can manifest in a variety of ways. Three of the most common are listed below: 

• Voice disorders affect the tone, pitch, quality, and volume of a person’s voice. A person with a voice disorder may have difficulty speaking or being heard clearly by others. Voice disorders can be either functional or organic. Functional disorders occur due to improper use of the parts of the throat that produce speech, such as overuse of the voice leading to vocal fatigue. Organic voice disorders result from physical anatomical changes, such as nodules on the vocal cords. 
• Fluency disorders affect the rate, rhythm, and cadence of speech. Those with fluency disorders may speak in a disjointed, choppy, or prolonged fashion, making them difficult for others to understand clearly. While many types of fluency disorders exist, stuttering is likely the best-known. Speech often requires precise timing to convey a message accurately, which fluency disorders can disrupt. 
• Speech sound disorders are a broad category of disorders that interferes with a person’s ability to produce sounds and words correctly. Speech sound disorders can present very differently from person to person. Sometimes word sounds are omitted or added where not appropriate, and sometimes word sounds are distorted or substituted completely. A typical example of a speech sound disorder is the substitution of “r” for “w” in words like “rabbit” (becoming “wabbit”). Many children experience that substitution, but it does not become a disorder until the child does not outgrow it. 

Other types of disorders can cause problems with expressive communication or tongue-tie those experiencing them, such as developmental language disorder. Language disorders also cause concerns related to expressive communication, but the concerns are due to a lack of understanding of one or more components of language, not an inability to produce or use word sounds. 

What do you call a speech impediment?

Speech impediments are typically referred to as speech disorders . Speech refers to the ability to form speech sounds using the vocal cords, mouth, lips, and tongue. Speech also requires that a rhythm and cadence be maintained. Speech disorders indicate a problem producing intelligible speech; word sounds may be omitted or misplaced, the rhythm of the speech may be difficult to follow, or a person’s voice might be strangely pitched or too soft to hear clearly. 

It is important not to confuse speech disorders with language disorders . Language disorders arise due to difficulty understanding what words mean, how word sounds fit together, or how to use spoken language to communicate. Language problems may affect how a person speaks, but the root cause of the concern is linked to their understanding of language, not their ability to produce intelligible speech. 

How do I know if I have a speech impediment?

If you’re experiencing a sudden onset of impaired speech with no apparent cause, seek medical attention immediately. Strokes, traumatic brain injuries, and other serious medical conditions can cause sudden changes in speaking ability. Gradual changes in speaking ability may also indicate an underlying medical problem. If you’re concerned that your speaking ability has been gradually deteriorating, consider making an appointment with a healthcare provider in the near future. 

Most people with a speech disorder are diagnosed in childhood. Parents often identify speech-related concerns in early childhood based on their child’s speech patterns. The child’s pediatrician may also refer the child to a speech-language pathologist, a professional specializing in evaluating and treating speech disorders. If problems persist until the child is in school, teachers and other school officials might initiate a referral for an evaluation if they believe speech concerns are present. Children often receive speech and language therapy that resolves or improves their speech problems. 

Speech disorders also appear in adulthood, often due to injury or illness. It is also possible, although rare, for speech problems to be misdiagnosed or missed outright during a person’s childhood. In that case, the speech disorder may have been present since childhood and symptoms persisted into adulthood.

If you’re finding it difficult to communicate verbally with others, have an easily identifiable speech problem (like stuttering), or receive feedback that others have trouble understanding you, consider making an appointment with your doctor for an evaluation and referral to the appropriate healthcare providers. 

What are 5 causes of speech impairment?

Speech and language disorders can result from conditions that interfere with the development of perceptual, structural, motor, cognitive, or socioemotional functions. The cause of many speech disorders is unknown, but research has indicated several underlying factors that may be responsible: 

• Pre-existing genetic conditions, like Down’s syndrome or Fragile X syndrome. Evidence suggests that genes may play a role even if genetic abnormalities do not result in a diagnosable genetic condition. 
• Physical abnormalities, such as damage or improper development of the respiratory system, facial muscles, or cranial nerves. 
• Hearing problems, which can delay a child’s acquisition of speech. 
• Neurodevelopmental disorders, such as autism spectrum disorder, may interfere with speech development. There is also evidence to suggest that those with attention-deficit hyperactivity disorder may have a more challenging time acquiring speech skills. 
• Neurological conditions such as cerebral palsy. 

Mental health concerns can also cause problems communicating with others. For example, an underlying anxiety disorder may lead to selective mutism , wherein a child speaks only under certain circumstances. 

Is speech impediment a disability?

A speech-language disorder is considered a “ communication disability ” under the Americans with Disabilities Act (ADA). The ADA requires government and businesses to establish “effective communication” with people who have communication disabilities. Effective communication can be established in several ways. For those with a speech disorder, accommodation may be as simple as ensuring the person can get hold of writing materials if they need to express themselves quickly. In some cases, organizations may use a transliterator, or person trained to recognize unclear speech and repeat it clearly. 

Because speech disorders are known to lead to academic struggles in K-12 and higher education settings, they are categorized as a disability under the Individuals with Disabilities Education Improvement Act (IDEIA) . The IDEIA sets guidelines for all schools in the United States, public or not public, guaranteeing each child a right to accommodations and interventions for their speech disorder. 

Can I fix my speech impediment?

Whether or not a speech disorder can be completely eliminated depends heavily on individual factors. The cause of the disorder, its severity, and the type of speech dysfunction all play a role in determining whether a particular disorder can be completely resolved. While it is not possible to guarantee that a speech disorder can be “cured,” nearly all disorders are treatable, and improvement is likely possible. 

Can you treat a speech impediment?

Yes, many speech disorders are highly treatable. Most people receive treatment as children when most speech disorders become apparent. For children, speech-language pathologists will identify the specific speech disorder, search for an underlying cause, and design an intervention that targets that child’s speech problem. For example, a child who struggles with articulation errors and producing word sounds consistently may benefit from a contextual utilization approach . Contextual utilization leverages the fact that one sound is easier or more difficult to pronounce depending on which other sounds surround it. 

Speech disorders that emerge in adulthood may be more challenging to treat due to underlying factors, such as brain injury. Suppose an adult experiences a traumatic brain injury that affects their speaking ability. In that case, a speech-language pathologist may help them find alternative communication methods, such as using a computer. They may also help them directly restore some of their speaking ability by leading them through exercises that improve nerve function and muscle control.  

Is a speech impediment mental?

Speech disorders can be caused by various factors, many of which have nothing to do with the brain. However, there is a relationship between psychiatric mental health concerns and difficulty with spoken communication . Although researchers are still unsure of the exact cause, studies have identified a significant link between speech disorders and mental health disorders like schizophrenia, bipolar disorder, and major depression. 

Neurodevelopmental disorders, such as autism spectrum disorder and attention-deficit hyperactivity disorder, are also associated with an increased risk of developing a speech disorder. Although the link between neurodevelopmental disorders and speech disorders is not fully understood, evidence suggests that treating the speech disorder is still possible. 

Finally, speech disorders can also be caused by illness or injury in the brain, such as cancer, an infection, or traumatic brain injury. Although these are not considered mental or developmental disorders, they may affect brain function and mental acuity. Speaking is a complex process, and there are many ways it can be affected. 

Is autism a speech impediment?

Autism spectrum disorder is not a speech disorder, but it is heavily associated with communication problems. Those on the autism spectrum often use repetitive or rigid language and may not follow communication norms. They may repeat phrases continuously, use a modified tone of voice, or introduce information that has little to do with the conversation at hand. 

Those on the autism spectrum are often able to form word sounds properly. The communication deficits of autism spectrum disorder are more closely related to language disorders than speech disorders. Speech disorders are associated with difficulty producing or using word sounds correctly, whereas language disorders are associated with a lack of understanding of one or more language components.

Autism spectrum disorder is also characterized by difficulties using pragmatic communication, or communication that is appropriate to a specific social situation. Although not a disorder of speech, a limited ability to recognize the socioemotional content of speech can significantly impact interpersonal communication and social interactions.

Five Common Speech Disorders in Children

You have determined that your child has more than just a speech delay, now what? How do you determine what kind of speech disorder your child has and more importantly, what do you do about it? We have listed below five common speech disorders in children. Of course, we always recommend a visit to your pediatrician if you feel your child has any of these symptoms, and an appointment with an SLP may be necessary to begin an effective speech therapy treatment plan.

5 Common Speech Disorders in Children:

Articulation Disorder: An articulation disorder is a speech sound disorder in which a child has difficulty making certain sounds correctly.  Sounds may be omitted or improperly altered during the course of speech. A child may substitute sounds (“wabbit” instead of “rabbit”) or add sounds improperly to words. Young children will typically display articulation issues as they learn to speak, but they are expected to “grow out of it” by a certain age.  If the errors persist past a standard developmental age, which varies based on the sound, then that child has an articulation disorder.

The most common articulation disorders are in the form of a “lisp” – when a child does not pronounce the S sound correctly – or when a child cannot pronounce the R sound correctly. He may say “wabbit” instead of “rabbit” or “buhd” or instead of “bird.”

Apraxia of Speech is a communication disorder affecting the motor programming system for speech production.  Speech production is difficult – specifically with sequencing and forming sounds. The person may know what he wants to say, but there is a disruption in the part of the brain that sends the signal to the muscle for the movement necessary to produce the sound.  That leads to problems with articulation as well as intonation and speaking stress and rhythm errors. Apraxia of Speech can be discovered in childhood (CAS), or might be acquired (AOS) resulting from a brain injury or illness in both children and adults.

Fragile X Syndrome (FXS) is an inherited genetic disorder that is the most common cause of inherited intellectual disabilities in boys as well as  autism  (about 30% of children with FXS will have autism). It also affects girls, though their symptoms tend to be milder. It is greatly under-recognized and second only to  Down syndrome  in causing intellectual impairment.

FXS occurs when there is a mutation of FMRI gene and is an inherited disorder.  If a child received a pre-mutated X chromosome from one of his parents (as a carrier), then he is at greater risk of developing FXS.  Diagnosing Fragile X Syndrome is not easy for parents and doctors at the beginning of a child’s life.  Few outward signs are noticeable within the first 9 months. These signs may include an elongated face and protruding eyes.

Intellectual disabilities, speech and language problems, and social anxiety occur most frequently in children with Fragile X. Speech symptoms include repetition of words and phrases, cluttered speech and difficulties with the pragmatics of speech. All of FXS’s symptoms can range from mild to very severe.

Stuttering occurs when speech is disrupted by involuntary repetitions, prolonging of sounds and hesitation or pausing before speech. Stuttering can be developmental, meaning it begins during early speech acquisition, or acquired due to brain trauma. No one knows the exact causes of stuttering in a child.  It is considered to have a genetic basis, but the direct link has not yet been found. Children with relatives who stutter are 3 times as likely to develop stuttering. Stuttering is also more typical in children who have congenital disorders like  cerebral palsy .

A child who stutters is typically not struggling with the actual production of the sounds—stress and a nervousness trigger many cases of stuttering. Stuttering is variable, meaning if the speaker does not feel anxious when speaking, the stuttering may not affect their speech.

Language disorders can be classified in three different ways: Expressive Language Disorder (ELD), Receptive Language Disorder (RLD) or Expressive-Receptive Language Disorder (ERLD).  Children with Expressive Language Disorder do not have problems producing sounds or words, but have an inability to retrieve the right words and formulate proper sentences. Children with Receptive Language Disorder have difficulties comprehending spoken and written language. Finally, children with Expressive-Receptive Language Disorder will exhibit both kinds of symptoms. Grammar is a hard concept for them to understand and they may not use of articles (a, the), prepositions (of, with) and plurals. An early symptom is delay in the early stages of language, so if your child takes longer to formulate words or starting to babble, it can be a sign of ELD.

Children with Receptive Language Disorder may act like they are ignoring you or just repeat words that you say; this is known as “echolalia.” Even when repeating the words you say, they may not understand.  An example of this is if you say, “Do you want to go to the park?” and they respond with the exact phrase and do not answer the question. They may not understand you or the fact that you asked them to do something.

Children with Expressive-Receptive Language Disorder can have a mix of these symptoms

These are some of the most common speech disorders in children. No child is the same and you know your child best. If you feel that your child has a speech disorder, contact your pediatrician to discuss treatment options.

Speech Sound Disorder (Phonological Disorder) DSM-5 315.39 (F80.0)

DSM-5 Category: Communication Disorders

Introduction.

Speech is the verbal expression of one's cognitive content and process, and emotions. Clarity of speech is essential to social interaction, and educational and occupational functioning, as well as one's self confidence, self image, and sense of self efficacy. Impairment in speech can have a negative influence on all of these areas. Speech Sound Disorder (SSD), formerly known as Phonological Disorder in the DSM -IV, (Diagnostic and Statistical Manual of Mental Disorders, fourth Edition) is a DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, fifth edition), diagnosis assigned to individuals who have difficulties in productive speech which interferes with communication, and produces impairment in functioning, and distress. In Speech Sound Disorder, phonemes, or the basic units of speech, can be added, omitted, distorted or changed, or substituted in a manner which makes the speaker difficult to understand (American Speech Language Hearing Association, 2014). Addition of sounds is defined as including unneeded sounds in the pronunciation of the word. Omission involves deleting sounds or syllables, e,g, the word Doggie is pronounced as “oggie”. Distortions involve altering the correct sound of the word, which includes lisping. Substitution is using an incorrect sound to pronounce the word, e.g., cry is pronounced as “Cwy”. Acquisition of articulate speech is a developmental process which unfolds over almost a decade from birth. At age two, about 50% of a child's speech should be intelligible, and by age four, speech should be mostly understandable. At age eight, all words used by a child should be intelligible. Difficulties with speech production outside of these normal developmental parameters, in the absence of a sensory -motor deficit, neurological problem, or facial structural abnormality can indicate Speech Sound Disorder (American Psychiatric Association, 2013).

Symptoms of Speech Sound Disorder

According to the DSM-5, there are four criterion for Speech Sound Disorder:

• Persistent unintelligible speech consisting of phoneme addition, omission, distortion, or substitution, which interferes with verbal communication.
• There is interference with either social participation, academic performance, or occupational performance (or any combination thereof).
• The onset of symptoms is during childhood.
• The symptoms cannot be accounted for by another medical or neurological condition, including TBI (Traumatic Brain Injury) (American Psychiatric Association, 2013).

The DSM-5 notes that the onset of Speech Sound Disorder is in childhood. (American Psychiatric Association, 2013). Speech Sound Disorder responds well to speech therapy, with good resolution, however, some speech errors can persist into adulthood.

The DSM-5 does not indicate the prevalence of Speech Sound Disorder (American Psychiatric Association, 2013). Other sources indicate the prevalence of Speech Sound Disorder is 8%-9% in children (National Institute on Deafness and other Communication Disorders, 2010).

Risk Factors

The DSM-5 does not list specific risk factors for Speech Sound Disorder (American Psychiatric Association, 2013). Other sources indicate children who experience frequent ear infections may develop hearing impairment and be at risk for Speech Sound Disorder (American Speech Language Hearing Association, 2014).

Comorbidity

The DSM-5 does not indicate any specific comorbid disorders with Speech Sound Disorder

(American Psychiatric Association, 2013). Other sources indicate Language Impairment (LI) is also seen in children with Speech Sound Disorder (Lewis, Avrich, Freebairn,Hansen, Sucheston, Kuo, Taylor, Iyengar, & Steina, 2011). If Speech Sound Disorder is not corrected, and a lisp or other speech impediment persists into adulthood, it can be a contributing factor in social anxiety disorder. Some individuals will be very self-conscious of their lisp, overestimating how noticeable it is by others, or assigning an overly negative impression to it.

Treatment for Speech Sound Disorder

The DSM-5 does not specify treatment options for Speech Sound Disorder(American Psychiatric Association, 2013). Speech Sound Disorder can be diagnosed, evaluated, and treated by an SLP (Speech Language Pathologist) (American Speech Language Hearing Association, 2014). In some cases, supportive psychotherapy may be beneficial to prevent Speech Disorders from contributing to Social Anxiety, or problems with self confidence, particularly in adults who are self-conscious about residual speech errors.

Impact on Functioning

Speech Sound Disorder can impact educational, interpersonal, and occupational functioning.

(American Psychiatric Association, 2013). Peers may bully or ridicule children who lisp, or have other indicators of Speech Sound Disorder. Children with Speech Sound Disorder, as well as adults with residual speech errors may be perceived as less intelligent, or mature, as speech production is generally considered a marker of one's intellect and maturity. Speech Sound Disorder can impact learning and literacy. Studies have shown that 18% of children with Speech Sound Disorder will have difficulty reading in elementary school by about third or fourth grade (Lewis, et al, 2011). Adults with unresolved Speech disorders may restrict their participation in certain activities to prevent revealing their speech difficulty (Board of Regents of the University Of Oklahoma, 2011)

Differential Diagnosis

There are several diagnostic rule-outs for the clinician to consider in Speech Sound Disorder. In the DSM -5, it is noted that disorders such as hearing impairment can in turn produce speech impairment, which if in excess of what is typically expected for the degree of hearing loss, can be diagnosed separately as Speech Sound Disorder. There may be structural facial abnormalities such as a cleft palette which can produce difficulty with speech articulation. Dysarthria is a discrete speech disorder due to a neurological disorder, such as cerebral palsy. Following a TBI affecting Broca's area (Productive speech center of the cerebral cortex), there may be difficulties with speech production, articulation, and ability to retrieve words appropriate for the context (aphasia). This is not only a different etiology, but different qualitatively than Speech Sound Disorder. Selective Mutism involves limited speech production secondary to anxiety, There are also normal speech variations which are not considered a Speech Sound Disorder, such as accents. (American Psychiatric Association, 2013). Accents are regional differences in pronunciation due to the influence and filtering of one language through another, e.g, in northern Vermont, the “Au” sound in the word Aunt is pronounced with an “ awh” sound, whereas in New York State the same word is pronounced with an “eh” sound. The difference is due to English being filtered through French, which is an ancestral language in northern Vermont. The correct pronunciation is relative, depending on the region.
