Augmentative and Alternative Communication (AAC) is any type of non-spoken communication. Augmentative means adding to someone’s speech. Alternative means that it will be used instead of speech. When you use something other than spoken words to express a thought, feeling, or idea, you’re using AAC! All humans use AAC every day — think about things like gestures, drawing pictures, writing, or facial expressions.
