AAC for Kids: A Parent’s Guide to Augmentative Communication
If your child finds it hard to use speech to be understood, you may have heard the term AAC — but what it actually means, and what it could look like for your family, isn’t always clear.
This guide explains AAC for kids in plain language: what it is, who it can help, the different types, and how a speech pathologist works with families to find the right approach for each child.
What is AAC?
AAC stands for augmentative and alternative communication. It's an umbrella term for any way of communicating that adds to or replaces speech.
"Augmentative" means it adds to whatever speech a child already has. "Alternative" means it can also stand in for speech when speech isn't yet accessible. Either way, the goal is the same — to give a child a reliable way to say what they want to say.
AAC can be as simple as gestures and signs, or as advanced as a tablet that speaks aloud whatever the child taps. There's no single "right" AAC — the best system is the one the child can use, the family can support, and that matches the way the child needs to communicate.
Who can benefit from AAC?
AAC isn't just for children who can't speak at all. It can support any child who has trouble being understood, gets frustrated when communicating, or whose speech is unreliable. That might include:
Children who are minimally verbal or pre-verbal
Children with autism who use language differently
Children with developmental delays affecting language
Children with motor speech disorders such as apraxia
Children with cerebral palsy or other conditions that affect speech production
Children with hearing differences
Children who can sometimes talk, but not in all situations or with all listeners
Starting AAC early gives a child a way to participate in conversations, choices, play and learning while their speech continues to develop in the background.
Types of AAC
AAC is usually grouped into three categories. Most children end up using a mix, depending on the situation.
Unaided AAC
Unaided AAC uses only the child's own body — no extra tools needed. This includes facial expressions, gestures, pointing, body language, and sign or key word signing. It's always available, but it depends on the listener understanding the same system.
Low-tech aided AAC
Low-tech AAC uses simple physical tools that don't need batteries or screens. Examples include picture cards, communication books, choice boards, visual schedules, and the Picture Exchange Communication System (PECS). These are affordable, easy to take anywhere, and a great way to introduce a child to the idea that symbols can mean things.
High-tech aided AAC
High-tech AAC uses devices that generate speech. The most common option in Australia is a tablet (iPad or similar) running specialist AAC software. The child selects symbols or words and the device speaks them aloud, so anyone — not just trained family — can understand straight away.
There are many different AAC apps and devices, with different page layouts, vocabularies and access methods. The right one depends on the child's age, motor skills, vision, language level and how they will use it day-to-day.
Common myths about AAC
A few worries come up again and again with parents who are new to AAC. The research is clear and reassuring [verify: cite consensus AAC research summary]:
AAC will not stop my child from talking. Children who use AAC are no less likely to develop speech — many actually develop more speech, because the pressure is taken off.
My child is too young for AAC. AAC can be introduced in early childhood. Babies and toddlers already use early forms of AAC every time they point or wave.
My child has to "earn" AAC by trying speech first. Communication is a basic right, not a reward. Children deserve a way to communicate from the start.
AAC is only for severe disabilities. Plenty of children use AAC temporarily, alongside speech, or only in some settings.
How a speech pathologist supports AAC
Choosing and learning AAC is a process, not a one-off purchase. At Access to Therapy, this work fits within our Integrated Speech and Language Program, so AAC sits alongside speech, language and play goals rather than separately.
Assessment and trialling
A speech pathologist will get to know your child's strengths, interests and communication needs before recommending anything. Where high-tech AAC may be a good fit, the clinician will trial different systems with your child — often borrowing devices or apps to test for a few weeks — before recommending one.
Teaching and modelling
Once an AAC system is chosen, the work is to teach everyone around the child how to use it. That includes you, siblings, grandparents, kindy teachers and school staff. The most powerful strategy is "modelling" — adults using the AAC system themselves to comment, ask and respond, so the child sees how it works in real life.
AAC and NDIS funding
For families with a National Disability Insurance Scheme (NDIS) plan, AAC devices, apps and the therapy time to set them up are often funded under capacity building or assistive technology budgets [verify: confirm NDIS funding categories]. A speech pathology assessment is usually needed to recommend a specific device, and this is something your speech pathologist can help with.
Supporting your child's AAC at home
The biggest predictor of success with AAC isn't the device — it's how much the child sees the system used. A few practical things help:
Keep the AAC device or book within easy reach, all the time
Use the system yourself, even just a few words at a time, throughout the day
Don't quiz — comment, narrate, and respond rather than asking the child to "show me"
Celebrate every attempt, even if it's a "wrong" button — your child is communicating
Talk with your speech pathologist about goals each term, so practice stays focused
Progress with AAC often looks small day-to-day and big over months. Patience and consistency matter more than getting everything perfect.
We work with families across Ipswich, Springfield and surrounding suburbs to introduce AAC in a way that fits your child and your everyday life.
