Augmentative and alternative communication (AAC) is “an area of clinical practice that addresses the needs of individuals with significant and complex communication disorders characterized by impairments in speech-language production and/or comprehension, including spoken and written modes of communication”. There are two types of AAC systems: unaided communication systems and aided communication systems. There are four components to consider when designing aided AAC systems. These include symbol representation, layout and organization, selection technique, and output or the feedback of the system about the selection. To achieve communicative competence, it is critical for an individual to have access to an AAC system, or systems, that meet their skills and needs. Vocabulary selected for individuals using AAC systems can be broken down into two categories: core and fringe vocabularies. The primary goal of AAC interventions is to maximize language and communication.
