When is Augmentative and Alternative Communication (AAC) typically used?

Augmentative and Alternative Communication (AAC) is specifically designed to support individuals who have significant expressive communication needs. This includes people who may have difficulty speaking or writing due to various conditions such as neurological disorders, developmental disabilities, or injuries that affect their ability to communicate verbally. AAC encompasses a range of tools and techniques, including picture exchange systems, speech-generating devices, and sign language, which help individuals express their thoughts, needs, and ideas more effectively.

The focus on significant expressive communication needs highlights the primary purpose of AAC: to provide means for communication when natural speech is impaired or absent. This utility is vital in promoting independence, participation in social interactions, and overall quality of life for individuals who rely on AAC systems.

While AAC could potentially support learning in other areas, such as reading or social skills, its primary function is to aid in communication. Therefore, the context of the need for AAC is directly related to expressive communication rather than being focused on non-communication purposes such as enhancing literacy or social skills education.
