Augmentative and alternative communication (AAC) refers to any form of communication that is not speech. AAC devices provide an alternate way to communicate using sight and touch. These devices can be as low-tech as a piece of paper with pictures for a child to point to. There are also high-tech devices like tablets with specialized apps for communicating.

Speech and language therapy is an important component of the treatment of autism. Impaired verbal and nonverbal communication abilities are some of the key signs of autism. Individual functioning levels vary; some children are able to communicate successfully, while others may be unable to talk at all or have difficulty making eye contact, expressing facial expressions, or using gestures.

Speech therapy for autism focuses on language and communication challenges and can aid in improving verbal, nonverbal, and social communication in children with autism. The ultimate goal is to assist the child in communicating more functionally and efficiently.

Many neurodiverse children struggle with speech and communication, leading to frustration and difficulty developing deep social relationships. Speech therapy addresses speech-related and communication challenges in people with autism.
