When a child can't yet rely on speech to be understood, AAC gives them a voice — and one of the biggest myths parents hear is that using it will keep their child from talking. The research says the opposite. Here's what AAC actually is and how it helps.
What is AAC?
AAC stands for augmentative and alternative communication — any method of communicating besides (or alongside) speech. It ranges from gestures and sign, to picture boards and PECS, to speech-generating apps and devices. The goal is simple: give a child a reliable way to express what they want, need, and think right now.
Will AAC stop my child from talking?
No. A large body of research shows AAC does not hinder speech — and often supports or increases it. Like baby sign, it takes the all-or-nothing pressure off communication: a child who can finally make themselves understood is more motivated to communicate every way they can, including with words.
Who benefits from AAC?
AAC helps children who are nonspeaking or minimally speaking, as well as kids with apraxia, complex communication needs, or anyone whose speech isn't yet meeting their needs. It's not a last resort or a sign of giving up on speech — it's a bridge to communication that can happen alongside speech therapy.
Types of AAC
- No-tech: gestures, facial expression, and sign.
- Low-tech: picture boards, communication books, and PECS.
- High-tech: speech-generating devices and apps (such as LAMP, Proloquo2Go, and TD Snap).
AAC isn't one-size-fits-all — the right system is chosen and set up with a speech-language pathologist, and earlier is generally better. Our SLPs are trained across these systems.

How a speech-language pathologist helps
An SLP evaluates how your child communicates, matches them to the right AAC system, and teaches both child and family how to use it — while continuing to build spoken language. Speech therapy requires a referral from your child's primary care provider (faxed to 901-589-9001).
