AAC Therapy: Giving Non-Speaking and Minimally Speaking Children a Voice

Augmentative and Alternative Communication (AAC) refers to any tool or strategy that supports or supplements spoken language for children who can't communicate effectively through speech alone. These tools range from low-tech options like picture exchange systems and communication boards to high-tech speech-generating devices and apps like Proloquo2Go and TouchChat.

AAC is appropriate for children with autism, childhood apraxia of speech, global developmental delay, Down syndrome, cerebral palsy, and many other conditions affecting communication. A child doesn't need a specific diagnosis to benefit — if they struggle to express wants, needs, and thoughts verbally, exploring AAC is worthwhile.

Will AAC stop my child from talking?

A widespread worry is that using AAC will discourage speech. Research consistently shows the opposite. When children have a functional way to communicate, the pressure to produce speech decreases, vocabulary exposure increases, and communication becomes intrinsically rewarding. Many children who begin with AAC develop more verbal speech over time, alongside their AAC use.

Speech-language pathologists who specialize in AAC evaluate a child's current communication and recommend the right tools — often the simplest system that provides functional communication. Aided Language Stimulation, where adults model the AAC system while speaking, helps children learn to use these tools naturally.

Early access to functional communication — whether through symbol boards, signs, or devices — reduces frustration and behavioral challenges while strengthening family connection. Waiting only delays the benefits a child gains from having a voice.
