Abstract
This narrative review examines the role of augmentative and alternative communication (AAC) in supporting communication development among nonspeaking autistic individuals. The reviewed literature suggests that AAC should not be treated as a last resort or as a threat to spoken language development; rather, it can function as an enabling communication pathway that may support, and in many cases strengthen, verbal communication over time. Across the studies included in the source document, early access to AAC, especially speech-generating devices and aided modeling, is consistently associated with improved communication opportunities, reduced frustration, and better participation in daily environments.
