What is AAC?

AAC stands for augmentative and alternative communication. In other words, it is a system that can help support communication. An AAC system can be used for many different types of communication breakdowns. It can be helpful for people of all ages who may be non-verbal, have word finding difficulties, or are hard to understand. AAC systems can be broken down into two categories: unaided vs. aided systems.

Unaided AAC- An AAC system that does not require an aide or a tool for communication. This includes gestures, facial expressions, body language, and even sign language.

Aided AAC- An AAC system that uses tools or materials to generate speech/language. This includes, but is not limited to, communication boards, symbol boards, keyboards, whiteboards, tablets.
