AAC and autism: answers to common parent questions

AAC gives an autistic child a way to communicate now, whether they speak a lot, a little or not at all. Research reviews have not found that AAC stops children from learning to talk; most studies found small gains in speech. Children don’t have to be “ready” first. To start, model: point to words on a board or app as you talk during everyday fun, and keep it with your child all day.

These are the questions parents ask most often. For decisions about your own child, talk to a speech-language pathologist (SLP) who knows them.

Will AAC stop my child from talking?

The research so far says no. Three reviews have looked at this question:

So the honest summary is: AAC doesn’t hold speech back, and it may help a little, but it isn’t a promise that a child will talk. Its first job is to give your child a way to communicate today, whatever happens with speech.

The professional guidance for speech-language pathologists says the same: some families believe AAC reduces the motivation to speak, but AAC may help improve natural speech when it’s used alongside other ways of communicating.4

My child talks a bit. Do they still need AAC?

They might. “Augmentative” means adding to speech, not replacing it. AAC can help when speech is hard to understand, and people who use AAC can use both speech and AAC to talk to others.5

For example, a child might say “juice” and “out” clearly but have no way to say “I don’t like that” or “my tummy hurts”. Or a child might talk at home but find words much harder when they’re upset or somewhere new. AAC gives them a way through those moments. An SLP can look at what your child can and can’t say yet, and suggest what would help. The same is true for many autistic adults: see AAC for autistic adults.

Is my child too young, or not ready yet?

There’s no “ready”. Some parents and professionals think young children aren’t ready for AAC until school age, but the professional guidance says there are no prerequisites for AAC, that it should be considered as early as possible, and that early AAC use can help develop speech and language.4 Children younger than three can start, and no thinking skills, test scores or milestones are needed first.5 See AAC for toddlers for how to begin.

Which kind of AAC is best for an autistic child?

There isn’t one best kind. AAC is customized for each person,5 and the right choice depends on how your child moves, sees, hears and learns, what they love, and where they need to communicate. An SLP matches the features of a system to the child, and trying a device for a while is often part of deciding.4

Many families use a mix: a paper board in the bath and at the park, a speech app at home and at school, and the child’s own gestures and signs. Read how to get started with low-tech AAC and how to choose an AAC app. Schedules, first-then boards and timers help with understanding the day: see visual supports for autism at home.

How do I teach my child to use it?

By using it yourself. Point to words on your child’s board or app while you talk to them, in real moments, without asking them to copy you. This is called modeling (also augmented input or aided language stimulation).4 A 2018 review of 48 studies found that interventions with this kind of modeling were generally effective at improving the expressive communication of children and young people with complex communication needs.6

Example bubbles play board with 12 pictures: more, again, big, little, go, stop, blow, help, my turn, your turn, bubbles and all done.
A play board for bubbles. A board for your child’s favorite activity is a good place to start modeling.

What it can look like with bubbles

You blow bubbles. “Bubbles! More bubbles.” (Point to more, then blow again.)

(Stop, and hold the wand near your mouth. Look at your child. Wait.)

(Your child looks at the wand, then at you.) You: “More? More bubbles!” (Point to more, then blow.)

Later: “Uh oh, all gone. All done.” (Point to all done.)

Our AAC modeling at home handout puts these habits on one page, the core word of the week plans give you one word to focus on at a time, and how to teach a child to use AAC covers modeling, waiting and responding in depth.

Should we save it for therapy, or limit it like screen time?

Neither. People who use AAC should always have access to their communication tools, and concerns about too much screen time don’t apply to screens used as part of an AAC system.4 Your child can only use AAC if it’s there when they have something to say: at meals, in the car, at bedtime and at the park.

For the same reason, don’t take it away as a consequence for behavior. It’s how your child talks. If the same tablet is also used for games and videos, ask your SLP about keeping the speech app on its own tablet, or locking the tablet to the app.

My child presses the same button over and over. Is that a problem?

Usually not. Pressing a button to hear what it says is one way children find out what the buttons do. Answer it sometimes as if it was meant (“Stop? OK, I’ll stop!”), and model another word next to it. If the sound becomes a problem in class, ask the SLP about volume settings rather than taking the device away.

What if my child doesn’t use it?

Give it time, and look at the setup with your SLP:

Try this today

  • Pick one thing your child loves and choose three words for it, like more, go and stop.
  • Model those words five times during that activity, without asking your child to copy you.
  • Pause at the best moment, and wait ten seconds.
  • Write down your questions for your child’s speech-language pathologist.
