Speech and Language Disorders

When a person is unable to produce speech sounds correctly or fluently, or has problems with his or her voice, then he or she has a speech disorder. Difficulties pronouncing sounds, or articulation disorders, and stuttering are examples of speech disorders.

When a person has trouble understanding others, or sharing thoughts, ideas, and feelings completely, then he or she has a language disorder.

Both children and adults can have speech and language disorders. They can occur as a result of a medical problem or have no known cause.
