Augmentative and Alternative Communication (AAC)
What Is AAC?
The use of multiple modalities to supplement or compensate for the spoken communication of an individual
-
Unaided: Nonspoken forms of communication using your body, including gestures and facial expressions that do not. Unaided is also no-tech
Aided: Communication that uses external support, such as a communication board with symbols or a pen and paper. This can be low-tech, mid-tech, and high-tech.
-
No-Tech: Does not use any materials other than your body—unaided communication.
e.g., gestures or facial expressions
Low-Tech: Use physical tools but do not require batteries, electronics, or power—aided communication.
e.g., communication books or choice cards
Mid-Tech: Uses some technology, but with limited customizations and dynamic displays -aided communication.
e.g., single message button or step-by-step communicator
High-tech: Advanced electronic communication devices that can have dynamic screens and customizable, robust language systems - aided communication.
e.g., Communication apps

Evaluation
An AAC evaluation is the first step in finding a communication system that truly works for an individual. At AugmentAbility Speech Therapy, our evaluations are personalized, collaborative, and focused on the communicator’s real-life needs—not just what looks good on paper. During the evaluation, we:
Learn about the communicator’s current communication skills—what’s working well, and what’s challenging
Explore their communication needs at home, school, work, and in the community
Look at access methods—how they can best use AAC (touch, switches, eye gaze, etc.)
Try a variety of low-, mid-, and high-tech AAC options
Involve family and team members to ensure the AAC will be supported everywhere
Collect data in real-life settings whenever possible
Trial
An AAC trial is a chance to test-drive different communication systems before choosing one to use long-term. During trials, we:
Explore a variety of AAC options (low-tech through high-tech speech-generating devices)
Match system features to the communicator’s needs, strengths, and preferences
Try different access methods (touch, switch, eye gaze, etc.)
Collect real-world data on ease of use, communication success, and motivation
Include family and support team input at every step
Therapy
Once we’ve identified a strong AAC match, we provide therapy focused on:
Building the user’s confidence and independence in communicating
Expanding vocabulary and sentence building
Supporting all forms of communication (speech, gestures, AAC)
Coaching families, educators, and support staff so AAC is available and supported everywhere
Teaching strategies for real-life communication—whether that’s telling a joke, asking for help, or sharing an opinion
