Augmentative Communication—What is it and Who benefits?

When we think about AAC (Augmentative and Alternative Communication), often we think of the idea of alternative communication. We think of children who are non-speaking or minimally-speaking and are learning another (alternative) system for communication such as American Sign Language or use of a Speech Generating Device (SGD). This is often an iPad or tablet with a robust communication software installed. Other common AAC systems include picture exchange systems, buttons, switches, and low-tech talkers with pre-programmed phrases. But how do we use these systems to augment communication? When might a speech therapist recommend trialing AAC as a form of augmented communication for people capable of spoken communication?

            By definition augmentative means to increase or have the power to increase, highlighting the ability of AAC to increase communication. Most of us use forms of augmentative communication throughout our day without even realizing it. Talking with our hands, using gestures and facial expressions, and writing a text instead of placing a call are all ways in which people augment communication.

Sometimes, though perhaps not as often as we should, speech therapists may recommend AAC systems for individuals with seemingly typical or functional spoken language skills for communication. Often referred to as part-time AAC users, these people often have functional spoken language expression, but may require use of an SGD due to limited speech clarity, difficulty with word finding, or when the brain is overwhelmed and it is difficult for the individual to access the higher cognitive functions like language.

Check out this episode of Two Sides of the Spectrum podcast. You can hear more from a part-time AAC user about their experience. You can also learn more about the six primary communication functions of AAC here.

In Montana, we have a great program called MonTECH. MonTECH is a statewide program that helps Montana residents find, try, and access assistive technology. They offer free consultations, equipment loans, training, and low-cost financing options to improve daily life, work, and mobility. You can see some of the low, mid, and high tech AAC options available to Montana residents through MonTECH here.
