Abstract: Augmentative and alternative communication (AAC) encapsulates a broad collection of technologies that enable both expression and reception of language. These technologies include high-tech text-entry systems, such as specialized keyboards, that compose messages in abstracted alphabets and produce speech or text as output. These technologies are used across the spectrum of ages and speech-language impairments, from congenital issues such as cerebral palsy and autism to acquired conditions including Parkinson’s disease and Alzheimer’s. Additionally, there are approximately 270,000 people in North America with spinal cord injuries, approximately 47% of whom develop quadriplegia (i.e., tetraplegia), in which partial or total paralysis of the limbs and face [Spears and Holtz, 2010, Walls et al., 2009] can necessitate the use of AAC devices.
