2. What is AAC? Augmentative and alternative communication (AAC) refers to communication that expresses our thoughts without oral speech. People with speech problems rely on AAC through facial expressions, gestures, symbols, pictures, and text. AAC aids help disabled people interact socially, learn interactively, and communicate effectively. Information acquired from American Speech-Language-Hearing Association: www.asha.org
