Augmentative and alternative communication

Augmentative and Alternative Communication (AAC) is the formal term for "non-speech communication". In fact, the difference between augmentative and alternative communication is merely the difference between partial and total dependency on non-speech communication.

• gesture and body language;
• manual sign;
• handwriting; and
• communication aids.

Communication aids are devices developed or adapted for use by people with severe communication impairments. Because these people have very varied skills, needs, and problems, there is a large range of communication aids.

Some people with severe communication impairments can use their hands; others cannot, and have to use alternatives, such as mouth sticks, headsticks, switches or eye-pointing. Some can read and spell; others cannot, and need communication aids on which language elements are represented by pictures or symbols. Some individuals use wheelchairs which can accommodate large communication devices; others walk and need small, light aids. Some have the funds to purchase high tech equipment; others do not.

A communication aid may be as simple as a piece of cardboard with "no" and "yes" written on it, or as complex as a laptop computer, controlled with a switch which speaks and allows the user to talk on the phone, access the Internet, or type an essay.

The best non-speech communication strategy (or combination of strategies) is the one which allows the person with severe communication impairment to communicate as freely as possible, in as many situations as possible, to the maximum number of people.
