What is AAC?
Augmentative and alternative Communication (AAC)
includes all forms of communication (other than oral
speech) that are used to express thoughts, needs, wants,
and ideas. We all use AAC when we make facial
expressions or gestures, use symbols or pictures, or
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 electronic
devices, are available to help people express
themselves. This may increase social interaction, school
performance, and feelings of self-worth. (ASHA)

autism, traumatic brain injuries, genetic conditions
(down syndrome), cerebral palsy, sensory deficits

devices requiring much more training and programing.
