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.

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.

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.

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.

Articulation Errors

Ankyloglossia, treating speech disorders.

A speech impediment, also known as a speech disorder , is a condition that can affect a person’s ability to form sounds and words, making their speech difficult to understand.

Speech disorders generally become evident in early childhood, as children start speaking and learning language. While many children initially have trouble with certain sounds and words, most are able to speak easily by the time they are five years old. However, some speech disorders persist. Approximately 5% of children aged three to 17 in the United States experience speech disorders.

There are many different types of speech impediments, including:

• Articulation errors

This article explores the causes, symptoms, and treatment of the different types of speech disorders.

Speech impediments that break the flow of speech are known as disfluencies. Stuttering is the most common form of disfluency, however there are other types as well.

Symptoms and Characteristics of Disfluencies

These are some of the characteristics of disfluencies:

• Repeating certain phrases, words, or sounds after the age of 4 (For example: “O…orange,” “I like…like orange juice,” “I want…I want orange juice”)
• Adding in extra sounds or words into sentences (For example: “We…uh…went to buy…um…orange juice”)
• Elongating words (For example: Saying “orange joooose” instead of "orange juice")
• Replacing words (For example: “What…Where is the orange juice?”)
• Hesitating while speaking (For example: A long pause while thinking)
• Pausing mid-speech (For example: Stopping abruptly mid-speech, due to lack of airflow, causing no sounds to come out, leading to a tense pause)

In addition, someone with disfluencies may also experience the following symptoms while speaking:

• Vocal tension and strain
• Head jerking
• Eye blinking
• Lip trembling

Causes of Disfluencies

People with disfluencies tend to have neurological differences in areas of the brain that control language processing and coordinate speech, which may be caused by:

• Genetic factors
• Trauma or infection to the brain
• Environmental stressors that cause anxiety or emotional distress
• Neurodevelopmental conditions like attention-deficit hyperactivity disorder (ADHD)

Articulation disorders occur when a person has trouble placing their tongue in the correct position to form certain speech sounds. Lisping is the most common type of articulation disorder.

Symptoms and Characteristics of Articulation Errors

These are some of the characteristics of articulation disorders:

• Substituting one sound for another . People typically have trouble with ‘r’ and ‘l’ sounds. (For example: Being unable to say “rabbit” and saying “wabbit” instead)
• Lisping , which refers specifically to difficulty with ‘s’ and ‘z’ sounds. (For example: Saying “thugar” instead of “sugar” or producing a whistling sound while trying to pronounce these letters)
• Omitting sounds (For example: Saying “coo” instead of “school”)
• Adding sounds (For example: Saying “pinanio” instead of “piano”)
• Making other speech errors that can make it difficult to decipher what the person is saying. For instance, only family members may be able to understand what they’re trying to say.

Causes of Articulation Errors

Articulation errors may be caused by:

• Genetic factors, as it can run in families
• Hearing loss , as mishearing sounds can affect the person’s ability to reproduce the sound
• Changes in the bones or muscles that are needed for speech, including a cleft palate (a hole in the roof of the mouth) and tooth problems
• Damage to the nerves or parts of the brain that coordinate speech, caused by conditions such as cerebral palsy , for instance

Ankyloglossia, also known as tongue-tie, is a condition where the person’s tongue is attached to the bottom of their mouth. This can restrict the tongue’s movement and make it hard for the person to move their tongue.

Symptoms and Characteristics of Ankyloglossia

Ankyloglossia is characterized by difficulty pronouncing ‘d,’ ‘n,’ ‘s,’ ‘t,’ ‘th,’ and ‘z’ sounds that require the person’s tongue to touch the roof of their mouth or their upper teeth, as their tongue may not be able to reach there.

Apart from speech impediments, people with ankyloglossia may also experience other symptoms as a result of their tongue-tie. These symptoms include:

• Difficulty breastfeeding in newborns
• Trouble swallowing
• Limited ability to move the tongue from side to side or stick it out
• Difficulty with activities like playing wind instruments, licking ice cream, or kissing
• Mouth breathing

Causes of Ankyloglossia

Ankyloglossia is a congenital condition, which means it is present from birth. A tissue known as the lingual frenulum attaches the tongue to the base of the mouth. People with ankyloglossia have a shorter lingual frenulum, or it is attached further along their tongue than most people’s.

Dysarthria is a condition where people slur their words because they cannot control the muscles that are required for speech, due to brain, nerve, or organ damage.

Symptoms and Characteristics of Dysarthria

Dysarthria is characterized by:

• Slurred, choppy, or robotic speech
• Rapid, slow, or soft speech
• Breathy, hoarse, or nasal voice

Additionally, someone with dysarthria may also have other symptoms such as difficulty swallowing and inability to move their tongue, lips, or jaw easily.

Causes of Dysarthria

Dysarthria is caused by paralysis or weakness of the speech muscles. The causes of the weakness can vary depending on the type of dysarthria the person has:

• Central dysarthria is caused by brain damage. It may be the result of neuromuscular diseases, such as cerebral palsy, Huntington’s disease, multiple sclerosis, muscular dystrophy, Huntington’s disease, Parkinson’s disease, or Lou Gehrig’s disease. Central dysarthria may also be caused by injuries or illnesses that damage the brain, such as dementia, stroke, brain tumor, or traumatic brain injury .
• Peripheral dysarthria is caused by damage to the organs involved in speech. It may be caused by congenital structural problems, trauma to the mouth or face, or surgery to the tongue, mouth, head, neck, or voice box.

Apraxia, also known as dyspraxia, verbal apraxia, or apraxia of speech, is a neurological condition that can cause a person to have trouble moving the muscles they need to create sounds or words. The person’s brain knows what they want to say, but is unable to plan and sequence the words accordingly.

Symptoms and Characteristics of Apraxia

These are some of the characteristics of apraxia:

• Distorting sounds: The person may have trouble pronouncing certain sounds, particularly vowels, because they may be unable to move their tongue or jaw in the manner required to produce the right sound. Longer or more complex words may be especially harder to manage.
• Being inconsistent in their speech: For instance, the person may be able to pronounce a word correctly once, but may not be able to repeat it. Or, they may pronounce it correctly today and differently on another day.
• Grasping for words: The person may appear to be searching for the right word or sound, or attempt the pronunciation several times before getting it right.
• Making errors with the rhythm or tone of speech: The person may struggle with using tone and inflection to communicate meaning. For instance, they may not stress any of the words in a sentence, have trouble going from one syllable in a word to another, or pause at an inappropriate part of a sentence.

Causes of Apraxia

Apraxia occurs when nerve pathways in the brain are interrupted, which can make it difficult for the brain to send messages to the organs involved in speaking. The causes of these neurological disturbances can vary depending on the type of apraxia the person has:

• Childhood apraxia of speech (CAS): This condition is present from birth and is often hereditary. A person may be more likely to have it if a biological relative has a learning disability or communication disorder.
• Acquired apraxia of speech (AOS): This condition can occur in adults, due to brain damage as a result of a tumor, head injury , stroke, or other illness that affects the parts of the brain involved in speech.

If you have a speech impediment, or suspect your child might have one, it can be helpful to visit your healthcare provider. Your primary care physician can refer you to a speech-language pathologist, who can evaluate speech, diagnose speech disorders, and recommend treatment options.

The diagnostic process may involve a physical examination as well as psychological, neurological, or hearing tests, in order to confirm the diagnosis and rule out other causes.

Treatment for speech disorders often involves speech therapy, which can help you learn how to move your muscles and position your tongue correctly in order to create specific sounds. It can be quite effective in improving your speech.

Children often grow out of milder speech disorders; however, special education and speech therapy can help with more serious ones.

For ankyloglossia, or tongue-tie, a minor surgery known as a frenectomy can help detach the tongue from the bottom of the mouth.

A Word From Verywell

A speech impediment can make it difficult to pronounce certain sounds, speak clearly, or communicate fluently. 

Living with a speech disorder can be frustrating because people may cut you off while you’re speaking, try to finish your sentences, or treat you differently. It can be helpful to talk to your healthcare providers about how to cope with these situations.

You may also benefit from joining a support group, where you can connect with others living with speech disorders.

Definition of impediment

Did you know.

Impediment comes from a Latin verb that meant "to interfere with" or "to get in the way of progress", as if by tripping up the feet of someone walking. In English, impediment still suggests an obstruction or obstacle along a path; for example, a lack of adequate roads and bridges would be called an impediment to economic development. Impediments usually get in the way of something we want. So we may speak of an impediment to communication, marriage, or progress--but something that slows the progress of aging, disease, or decay is rarely called an impediment.

• embarrassment
• encumbrance
• interference
• obstruction
• stumbling block

Google Changed Its Definition of 'Bloodbath' After Trump Used It in a Speech?

Social media users concocted a conspiracy theory to counter criticism of trump's use of the word., aleksandra wrona, published march 28, 2024.

About this rating

On March 16, 2024, former U.S. President Donald Trump said : "Now, if I don't get elected, it's going to be a bloodbath for the whole — that's gonna be the least of it. It's going to be a bloodbath for the country." His remark at a campaign rally in Dayton, Ohio, sparked controversy on social media. As Snopes reported on March 17, 2024, its context suggested Trump was predicting an "economic bloodbath" for the country, not a literal one, if he loses the 2024 presidential election.

Five days later, on March 21, 2024, a rumor went viral on X (formerly Twitter), alleging that Google intentionally changed "its definition" of "bloodbath" to push an anti-Trump narrative. This claim is not only false, as we'll demonstrate below, but based on a complete ignorance of how the search engine's "dictionary boxes" work. But that didn't keep the rumor from going viral.

"HOLY S***. Google just quietly changed its search results for 'bloodbath definition'," the most viral post on the topic read, reaching over 35 million views as of this writing. The post featured a collage of two screenshots supposedly proving Google tampered with the search results for "bloodbath" between March 17, 2024, and March 21, 2024.

(X user @EndWokeness)

"Definition changed from how it was 4 days ago. Changed to remove the financial example, to ensure Trump's speech can always be taken out of context. Re-writing the meaning of words in real time," one Reddit user commented . Even Elon Musk, the owner of X, went all-in on the conspiracy theory. "Google is deeply infected with the woke mind virus" Musk wrote in an X  repost  of the above-mentioned collage to his 178 million followers. 

How 'Dictionary Boxes' on Google Really Work

According to a Google Search Help article  titled "Dictionary boxes on Google," these so-called "dictionary boxes" display definitions from third-party sources. It emphasized that "Google doesn't create, write, or modify definitions" and "dictionary results don't reflect the opinions of Google" (emphasis ours):

When you search on Google, you might find dictionary boxes if our systems decide it would be useful and relevant. Dictionary boxes show definitions from third-party expert sources and might include related images, pronunciations, translations, and other information. Tip: You're likely to get a Dictionary result when you start your search with "Define" or "What's the meaning of." Where info in Dictionary boxes comes from Important: Dictionary boxes always include definitions but might not include all other features. Definitions Google doesn't create, write, or modify definitions. Dictionary results don't reflect the opinions of Google. We license definitions, which include examples, similar and opposite words, and origins, from third-party experts who compile dictionaries. Tip: At the top of a Dictionary box, you can usually find the provider of the definition.

We reached out to Google directly to ask for its response to the claim that the definitions were purposely changed. "This allegation is categorically false," a spokesperson told us. "These definitions come from dictionaries, not from Google. We don't create, write, or modify definitions, and we don't manually decide which results appear. Both of these definitions have shown up for this search and related searches in recent days. " 

This confirms what various social media users had pointed out: The viral image didn't show an individual dictionary entry that had changed; it showed definitions from two different sources, Dictionary.com website and Oxford Languages (see image below). 

When we took a closer look at the viral image, we noticed the two screenshots were significantly different. The first one showed an "About featured snippets" caption, while the second one showed a "Dictionary, Definitions from Oxford Languages" legend. When we clicked on the "Oxford Languages" button, it redirected us to an Oxford Languages article, informing that "Google's English dictionary is provided by Oxford Languages."

The first screenshot, allegedly captured on March 17, 2024, informed the displayed search result was a "featured snippet." A Google Search Help  article  with the title "How Google's featured snippets work" said that "Google's search results sometimes show listings where the snippet describing a page comes before a link to a page, not after as with our standard format. Results displayed this way are called 'featured snippets.'" It continued (emphasis ours):

You might find featured snippets on their own within overall search results, within the "People also ask" section, or along with Knowledge Graph information. We display featured snippets when our systems determine this format will help people more easily discover what they're seeking, both from the description about the page and when they click on the link to read the page itself. They're especially helpful for those on mobile or searching by voice. Featured snippets commonly contain one listing, but more than one may appear. How featured snippets are chosen Featured snippets come from web search listings. Google's automated systems determine whether a page would make a good featured snippet to highlight for a specific search request. Your feedback helps us improve our search algorithms and the quality of your search results.

Ultimately, Google search results are based on many factors, such as one's location or the phrasing of the query, which might cause differences in the search results over time:

To give you the most useful information, Search algorithms look at many factors and signals, including the words of your query, relevance and usability of pages, expertise of sources, and your location and settings. The weight applied to each factor varies depending on the nature of your query. For example, the freshness of the content plays a bigger role in answering queries about current news topics than it does about dictionary definitions.

We have fact-checked other Google-related rumors before. For instance, in June 2023, we investigated whether Google Maps was adding a feature that would allow drivers to challenge each other to a race. In January 2023, we debunked a false claim that a Google product designed to compete with Apple's AirTag and Samsung's SmartTag was named the "G-Spot."
