Augmentative and Alternative Communication (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. ACC is used to communicate and express ourselves. Everyone uses AAC when they make facial expressions or gestures, use symbols or pictures, or write. People with severe speech or language problems rely on AAC to replace existing speech or substitute for speech when is not functional. There are a number of special augmentative aids, such as picture and symbol communication boards and electronic devices which enable people to express themselves. These can often increase social interaction, participation in the school setting, and feelings of self-worth. AAC users should not stop using speech if they are able to do so. The AAC aids and devices are not in place of speech if it is able to be usedbut can enhance their communication.

What are the types of AAC systems?

When children or 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 SGD's)and/or written output. Electronic communication aids allow the user to use picture symbols, letters, and/or words and phrases to create messages. Some devices can be programmed to produce different spoken languages.
