What is AAC? Augmentative alternative communication or AAC refers to the systems and devices that help people with limited verbal skills or who are nonverbal communicate with others.

We all use AAC. Every time you make a thumbs-up sign, scribble a note and pass it to someone, or throw a knowing glance across the room without speaking, you engage in AAC.

However, there has been some confusion over what exactly AAC is all about. In today’s post, we’ll go over the basics of AAC, what it can do, and who benefits from it.

What is the difference between augmentative communication and alternative communication?
AAC is divided into two main forms of communication: augmentative and alternative.

Augmentative communication uses systems/devices to supplement natural speech. For instance, a small portable amplifier can increase speech volume and help those with limited vocal capacity communicate effectively.

Alternative communication uses systems/devices to replace natural speech. A keyboard text-to-speech program, or even something as simple as a communication board, are tools that enable alternative communication. Users of alternative communication devices typically do not have the ability to communicate verbally.

Initially, this field was simply called “augmentative communication.” The term “alternative” was later added to stress that communication devices can either enhance or replace natural speech.

In 1983 the International Society for Augmentative and Alternative Communication was established as the world’s premier organization working to serve the needs of children and adults with complex communication needs.
