Augmentative and alternative communication (AAC) is a set of tools and strategies that help individuals experiencing challenges with face-to-face (spoken) or written communication express themselves more effectively.

Some key AAC definitions include:

Alternative Communication – a system of communication that is used instead of speech or handwriting
Augmentative Communication – a system of communication that makes the most of a person’s existing speech/handwriting skills, and supplements these skills with other ways of communicating
Face-to-Face AAC Examples – Sign language; pointing to a symbol or photo that represents what the child is trying to communicate; activating a button on a tablet that speaks a pre-recorded message
Written Communication Examples – a computer with adapted hardware (i.e. – switch activation) or software (i.e. – on-screen keyboard, voice recognition)
