Augmentative and Alternative Communication encompasses all methods of communication beyond speech that help people express themselves. AAC ranges from 'low-tech' tools like picture boards, communication books, and sign language to 'high-tech' speech-generating devices and tablet-based apps (such as Proloquo2Go, TouchChat, and LAMP Words for Life). AAC is used by people with autism, cerebral palsy, apraxia, ALS, stroke, and other conditions that affect speech. Research consistently shows that AAC does not prevent speech development — in fact, it often supports it. AAC is considered a right, not a last resort. Speech-language pathologists assess individuals for the appropriate AAC system based on motor skills, language level, and communication needs.
AAC devices and training are covered under most HCBS waivers and state Medicaid plans. Early AAC access can transform a child's ability to communicate while waiting for other waiver services.
