AAC
Also written as: AAC — Augmentative and Alternative Communication
A set of tools, strategies, and techniques used to supplement or replace natural speech or writing for individuals with communication impairments.
Full Definition
Augmentative and Alternative Communication (AAC) refers to all forms of communication other than oral speech used to express thoughts, needs, and ideas. AAC systems may be unaided (such as sign language or gestures) or aided (such as picture boards, speech-generating devices, or dedicated software). In editorial contexts, 'AAC' should always be expanded on first use within a document. Editors should note that 'augmentative' and 'alternative' are distinct concepts: augmentative supplements existing speech, while alternative replaces it entirely. The acronym is always written in full capitals with no periods.
Usage
Usage note: Expand 'AAC' to 'augmentative and alternative communication' on first use. Never write as 'Augmentative & Alternative Communication' in formal documents; spell out 'and'.
