Augmentative and alternative communication (AAC) is an umbrella term that encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language. AAC is used by those with a wide range of speech and language impairments, including congenital impairments such as cerebral palsy, intellectual impairment and autism, and acquired conditions such as amyotrophic lateral sclerosis and Parkinson's disease. AAC can be a permanent addition to a person's communication or a temporary aid.

Investigating executive functions in children with severe speech and movement disorders using structured tasks

Executive functions are the basis for goal-directed activity and include planning, monitoring, and inhibition, and language seems to play a role in the development of these functions. There is a tradition of studying executive function in both typical and atypical populations, and the present study investigates executive functions in children with severe speech and motor impairments who are communicating using communication aids with graphic symbols, letters, and/or words.

Effects of icon size and location on speed and accuracy of SGD access

The primary goal of these devices and the supporting interventions is to offer timely, consistent, expressive communication options to individuals who have limited natural speech. An important secondary purpose of an AAC system, especially for young users with developmental disabilities, involves supporting language acquisition.
