Types of AAC Systems
AAC systems fall into two categories: unaided (using the body, such as sign language or gestures) and aided (using external tools). Aided AAC ranges from low-tech options like picture boards and communication books to high-tech speech-generating devices (SGDs). Modern high-tech AAC primarily uses tablet-based apps such as Proloquo2Go, TouchChat, LAMP Words for Life, and Grid for iPad, which generate spoken output when the user selects symbols or types words.
Dedicated speech-generating devices from manufacturers like Tobii Dynavox and PRC-Saltillo offer specialized hardware with durable cases, eye-tracking capabilities, and switch access for individuals with motor challenges. The choice between tablet-based apps and dedicated devices depends on the individual motor abilities, communication needs, cognitive level, and environmental demands.
In Ontario, CASLPO-registered speech-language pathologists conduct AAC assessments to determine the most appropriate system. This assessment evaluates language comprehension, motor abilities, visual skills, and communication environments to recommend a matched AAC solution. The assessment report is required for ADP funding applications.
Funding AAC in Ontario
Ontario Assistive Devices Program may fund approved communication aids for eligible applicants. Product eligibility, required clinical authorization, and the applicant share can change, so use the current ADP policy and an authorized clinic rather than relying on a general percentage.
OAP or private insurance may cover some assessment, training, or device expenses, but one program does not automatically cover another programs balance. Get written confirmation from each payer before purchase.

Before you commit
- Questions worth asking any provider
- What certification or regulatory college licenses you to deliver this therapy, and can I verify it?
- How will you measure progress, and how often will you share results with our family?
- What does a typical session look like, and can we observe one before committing?
- How does this approach get adjusted if it is not working after a few months?
- What happens to our data, our schedule, and our funding if you leave or the practice closes?
- Signs to slow down
- The provider cannot name a regulatory college or certifying body, or asks you not to check it.
- You are asked to sign a long-term contract before seeing a session or meeting the therapist.
- Progress is described only in general terms, with no way to see or measure it over time.
- The provider discourages you from getting a second opinion or asking about other approaches.
- Fees, cancellation terms, or what OAP funding covers are unclear or change after you sign up.
Frequently asked questions
ADP may fund approved communication aids for eligible Ontario applicants. Coverage, required authorizers, approved products, and the applicant share depend on current program rules. An authorized clinic can confirm the pathway before purchase.
No. Research consistently demonstrates that AAC use does not inhibit and may actually support speech development. A 2006 systematic review by Millar, Light, and Schlosser found that AAC intervention either maintained or increased speech production in the majority of participants. AAC provides reliable communication while verbal skills continue to develop.
There is no single "best" AAC app — the right choice depends on your child's language level, motor abilities, and learning style. Popular options include Proloquo2Go (large vocabulary system), TouchChat (customizable), and LAMP Words for Life (motor-planning based). A CASLPO-registered speech-language pathologist can conduct an assessment to recommend the best match.
