augmentative and alternative communication (AAC)
How AAC Helps a Child with Speech and Language Delay
AAC gives a child with speech and language delay a reliable way to communicate — through pictures, symbols, sign or speech-generating devices — while spoken words develop. Evidence shows AAC supports rather than replaces talking, lowering frustration and building the foundations of language. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care.
When words are still on their way, AAC gives your child a voice today — so they can ask, share and connect right now, not someday.
In short
Augmentative and alternative communication (AAC) gives a child with speech and language delay a reliable way to communicate while spoken words develop — through pictures, symbol boards, sign, or speech-generating apps and devices. Far from replacing speech, decades of evidence show AAC actually supports talking by reducing frustration and giving your child a model of how language works. It is one of the most powerful tools we have to help a delayed communicator be understood today.How AAC helps your child
- A voice while speech develops — your child can request a snack, refuse, comment or greet using a picture, sign or button, instead of melting down or giving up. Being understood lowers frustration for the whole family.
- *It does not stop talking — it encourages it. This is the most common worry parents have, and the research is reassuring: children who use AAC often increase* their spoken words, because AAC lowers pressure and shows language in action.
- It builds the foundations of language — taking turns, knowing words have meaning, combining ideas ("more" + "juice"). These are the building blocks spoken sentences are built on.
- It grows with your child — AAC ranges from simple picture cards ("low-tech") to tablet apps and speech-generating devices ("high-tech"). A speech therapist matches the system to your child's age, abilities and interests, and changes it as they progress.
- Everyone learns together — parents, siblings and teachers learn to model the system, so communication happens everywhere, not only in therapy.
Think of AAC as a bridge, not a destination — it carries your child across to connection while their own words are catching up.
When to seek a check
Consider a speech and language assessment if your child is well behind in talking for their age, relies on pointing, grabbing or crying to be understood, shows frustration at not being understood, or seems to understand far more than they can say. Early support is always better — you do not need to "wait and see" before getting a professional view.The Pinnacle way

From there your child receives a precise communication profile through a clinician-administered structured assessment, and a plan that may pair AAC with speech and language therapy so spoken words are nurtured alongside.

What to watch
Watch for a child well behind in talking for their age, who relies on pointing, grabbing or crying to be understood, shows frustration at not being understood, or who clearly understands far more than they can say.
Try this at home
Model the AAC system yourself — point to or press the picture for 'more', 'help' or 'finished' as you say the word aloud, so your child sees that symbols carry meaning. No pressure to copy you.

Frequently asked
Will using AAC stop my child from learning to talk?
No — this is the most common worry, and the evidence is reassuring. Children who use AAC often increase their spoken words, because AAC lowers frustration and shows language in action. It is a bridge to speech, not a replacement for it.
What does AAC actually look like?
AAC ranges from simple picture cards and symbol boards (low-tech) to tablet apps and speech-generating devices (high-tech), and can include sign. A speech therapist chooses and adapts the system to suit your child's age, abilities and interests.
At what age can AAC start?
AAC can begin early — even before a child is talking — and grows with them. There is no need to wait and see. If your child struggles to be understood, a speech and language assessment can guide the right starting point.
