AAC 101: What Every Parent Should Know

AAC stands for Augmentative and Alternative Communication, and it's one of the most misunderstood tools in speech therapy. If your child's therapist has brought it up, or you've seen a child using a picture board or a speech-generating app, here's a quick primer.

What AAC actually is

AAC is any tool or strategy that supports or replaces spoken communication. That's a broad definition on purpose. It includes low-tech options like picture cards and communication boards, as well as high-tech options like tablet-based speech-generating apps.

Myth: AAC will stop my child from talking

This is the concern I hear most, and the research consistently says the opposite. AAC doesn't replace speech development. For many kids, it actually supports it, by lowering frustration and giving them a reliable way to communicate while their spoken language continues to grow.

Who might benefit from AAC

AAC isn't just for children who are entirely nonverbal. It can help kids with limited speech, inconsistent speech, or speech that's hard for unfamiliar listeners to understand, giving them a reliable backup so they're never stuck without a way to express themselves.

It's not all or nothing

AAC use often changes over time. A child might rely heavily on a device at three and use it much less by six as their spoken language catches up. Or they might use a mix of speech and AAC for years. Both are completely valid outcomes.

If it's recommended for your child

Try to approach it with curiosity rather than worry. A good AAC recommendation comes from wanting to give your child more ways to be understood, not fewer. Ask your therapist to show you how it works and how you can support it at home. The more it's used across settings, the more useful it becomes.
