Augmentative and Alternative Communication (AAC)
[
en Español]
What is 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. We all use AAC when we
make facial expressions or gestures, use symbols or pictures, or
write.
People with severe speech or language problems rely on AAC to
supplement existing speech or replace speech that is not
functional. Special augmentative aids, such as picture and symbol
communication boards and electronic devices, are available to
help people express themselves. This may increase social
interaction, school performance, 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 used to 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.
