Recognizing Speech and Language Disorders
Speech is the communication of spoken words. Speech consists of the following:
- Articulation—how speech sounds are produced
- Voice—coordination of vocal folds and breathing to produce sounds
- Fluency—the rhythm of speech
Language is shared system of rules accepted by a community to communicate ideas or feelings. Language consists of the following:
- Semantics—the meaning of words
- Morphology—units of meaning to make new word (e.g. love, lovely, loveliest)
- Syntax—rules of grammar on how to put words together
- Pragmatics—rules of social interactions
- Apraxia—motor planning disorder not caused by muscle weakness or paralysis. The brain has problems planning to move the body parts needed for speech.
- Dysarthria—difficulty articulating words due to disease of the central nervous system.
- Orofacial myfunctional disorder—exaggerated forward tongue movement during speech and/or swallowing.
- Articulation disorder—difficulty producing sounds.
- Phonological disorder—involves patterns of sound errors.
- Stuttering—the constant disruptions in the productions of speech sounds that affect day to day activities.
- Voice disorders—there are different types of voice disorders.
- Vocal cord nodules and polyps
- Vocal cord paralysis
- Paradoxical vocal fold movement (an episode occurs, during breathing vocal fold closes when they should stay open)
- Receptive language disorder—difficulty understanding spoken and written language.
- Expressive language disorder—characterized by difficulty expressing thoughts, needs, or wants at the same level as his/her peers.
- Language based learning disability—problems with reading, spelling and/or writing. Often children with reading difficulties have spoken language problems. Spoken language provides the foundation for the development of reading and writing.
