Augmentative-Alternative Communication (AAC) includes all forms of communication (other than oral speech) that are used to express thoughts, needs, wants, and ideas.
When children and adults cannot use speech to communicate effectively in all situations, there are options:
Unaided Communication Systems: rely on the user's body to convey messages.
Examples include gestures, body language, and/or sign language.
Aided Communication Systems: require the use of tools or equipment in addition to the user's body. Aided communication methods can range from paper and pencil to communication books or boards to devices that produce voice output (speech generating devices or SGDs) and/or written output.
Electronic communication devices allow the user to use pictures symbols, letters, and/or words and phrases to create messages.
