What is augmentative and alternative communication (AAC)?

When words don't come easily, communication still can — through pictures, symbols, signs and speech-generating devices that give every child a voice.

In short

Augmentative and alternative communication (AAC) is a set of tools and strategies that support or replace spoken language so a child can express their needs, thoughts and personality. Augmentative means adding to whatever speech a child already has; alternative means offering another route when speech is very limited or not yet emerging. AAC ranges from simple picture cards and gestures to tablet apps and speech-generating devices — and, crucially, it does not stop a child learning to talk; research shows it often encourages spoken language to grow.

What AAC looks like

AAC is usually grouped into two broad families. Unaided AAC uses only the body — gestures, facial expression, key-word signing and pointing. Aided AAC uses something external, which can be low-tech (picture boards, communication books, symbol cards) or high-tech (tablet apps and dedicated speech-generating devices that 'speak' when a child selects words or symbols). A speech and language therapist helps choose and personalise the right system for each child, building a vocabulary that fits their world — family names, favourite foods, play, feelings — and coaching the people around the child to model and respond. AAC suits many children: those who are minimally verbal, autistic children, children with cerebral palsy, apraxia of speech, or developmental delays affecting talking.

A common worry, gently answered

Many families ask whether giving a child a 'shortcut' to communicate will make them stop trying to talk. The evidence is reassuring: AAC reduces the frustration of not being understood, builds the back-and-forth of communication, and is consistently linked with gains in spoken language, not losses. Think of AAC as a bridge that carries a child across to richer communication — by any means available — while speech continues to develop alongside it.

The Pinnacle way

This is general information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our speech therapy teams assess how your child communicates today, then introduce AAC as part of a warm, individualised plan that grows with them.
