Communication Disorders

A communication disorder is an impairment in the ability to receive, send, process, and comprehend concepts or verbal, nonverbal and graphic symbol systems. A communication disorder may be evident in the processes of hearing, language, and/or speech. A communication disorder may range in severity from mild to profound. It may be developmental or acquired. Individuals may demonstrate one or any combination of communication disorders. A communication disorder may result in a primary disability or it may be secondary to other disabilities.   www.asha.org

Speech Sound Disorders

Articulation

Children may say some sounds the wrong way as they learn to talk. They learn some sounds earlier, like p, m, or w. Other sounds take longer to learn, like z, v, or th. Most children can say almost all speech sounds correctly by 4 years old. A child who does not say sounds by the expected ages may have a speech sound disorder. You may hear the terms "articulation disorder" and "phonological disorder" to describe speech sound disorders like this.   www.asha.org

Childhood Apraxia of Speech

In order for speech to occur, messages need to go from your brain to your mouth. These messages tell the muscles how and when to move to make sounds. When a child has apraxia of speech, the messages do not get through correctly. The child might not be able to move their lips or tongue in the right ways, even though their muscles are not weak. Sometimes, the child might not be able to say much at all.   www.asha.org

Language Disorder

A language disorder is an impairment in comprehension and/or use of a spoken, written, and/or other communication symbol system (e.g., American Sign Language). The disorder may involve the form of language (phonology, morphology, syntax), the content of language (semantics), and/or the function of language in communication (pragmatics) in any combination (ASHA, 1993).   www.asha.org

Children with language disorders may also present with social communication difficulty since social communication comprises social interaction, social cognition, pragmatics, and language processing.   www.asha.org

Fluency Disorder

Fluency is the aspect of speech production that refers to continuity, smoothness, rate, and effort. Stuttering, the most common fluency disorder, is an interruption in the flow of speaking characterized by repetitions (sounds, syllables, words, phrases), sound prolongations, blocks, interjections, and revisions, which may affect the rate and rhythm of speech. Cluttering, another fluency disorder, is characterized by a perceived rapid and/or irregular speech rate, which results in breakdowns in speech clarity and/or fluency (St. Louis & Schulte, 2011).   www.asha.org

Voice Disorder

A voice disorder occurs when voice quality, pitch, and loudness differ or are inappropriate for an individual's age, gender, cultural background, or geographic location (Aronson & Bless, 2009; Boone, McFarlane, Von Berg, & Zraik, 2010; Lee, Stemple, Glaze, & Kelchner, 2004).
