AAC, or Augmentative and Alternative Communication, includes all forms of communication (other than oral speech) used to express thoughts, needs, wants, and ideas. (American Speech-Language Association)
AAC Facts
People with severe speech or language problems rely on AAC to supplement existing speech or replace speech that is not functional. Special augmentative aids such as picture and symbol communication boards and/or electronic devices are available to help people express themselves. These may increase social interactions, school performance, and feelings of self-worth. (American Speech-Language Association)
Children who use AAC have shown improvement in behavior, attention, independence, self-confidence, participation, academic progress, and social interaction. (Abrgamsen, Romski & Sevcik, 1989, Silverman, 1980, Van Tatenhave, 1987)
