This review found no evidence that augmentative and alternative communication (AAC) intervention hinders speech production in children on the autism spectrum and suggests that AAC may result in increased speech production. The authors note that the "observed gains in speech production may vary across individuals and, if they do occur, are typically small in magnitude" (p. 227).
