Augmentative and Alternative Communication (AAC) is a term that is used to describe various methods of communication that can help people who are unable to reliably use verbal speech to communicate. AAC can benefit a wide range of individuals, from a beginning communicator to a more sophisticated communicator. 

AAC includes both unaided and aided systems. Unaided systems, like signing and gestures do not require special materials or equipment. Aided systems use picture charts, books, iPads, or special communication devices. Most individuals who use AAC have a combination of systems and strategies that are used to support different communication needs. AAC methods vary and may be personalized to meet an individual’s needs.

Any person who is unable to reliably use verbal speech to communicate is appropriate for AAC. This includes individuals who are limited in verbal speech, unintelligible, aphasic, or echolalic.

AAC evaluations are available for TEAM patients whose verbal communication does not meet their needs.  As soon as the treatment team determines the need, the AAC evaluation process can begin.  The process involves completion of our 10-step AAC workbook that includes pre-assessment, completion of trials, formal evaluation, funding, and implementation.  This process will be led by your child’s speech-language pathologist, with the support of our AAC specialists.

If you aren’t sure if an AAC is appropriate for your child, discuss your concerns with your child’s therapist. Additionally, a member of our AAC evaluation team can meet with you to help you decide what is best for your unique situation.

Common Myths about AAC

Myth: AAC is a “last resort” in speech-language intervention.

Fact: The use of AAC interventions should not be contingent on failure to develop speech skills or considered a last resort because AAC can play many roles in early communication development. Cress & Marvin, 2003; Reichle, Buekelman & Light, 2002

Myth: AAC hinders or stops further speech development.

Fact: For very young children, the use of AAC does not appear to hinder speech development. In fact, it may enhance the development of spoken communication, which should be a simultaneous goal for intervention. Cress, 2003, Romski, 2005

Myth: Speech-generating AAC devices are only for children with intact cognition.

Fact: The technological developments in AAC devices have made a broad range of options available. There are now many choices of AAC devices that speak, from simple technology (like single switches) to complex systems, that permit access to a variety of language and literacy skills. Romski, 2005

Myth: AAC is only for children who are nonverbal.

Fact: AAC is for any patient who does not have reliable verbal speech. If your patient does not have effective expressive communication, consider AAC.
