Someone, maybe a therapist, maybe a grandparent, has suggested picture cards, signs or a talking app, and your stomach dropped. If we give him another way, will he ever bother to speak? It is one of the most common fears in this whole journey, and one of the best answered.
The fear, stated fairly
The worry makes intuitive sense. Speech is hard for your child. If a sign or a button gets the juice box faster, why would they do the hard thing? Parents also hear that a device "labels" a child as non-speaking, or that a school will stop trying once the iPad appears.
The intuition is wrong because it treats communication as a single lane. It is not. Children who can communicate more, in any form, get more responses, more back-and-forth, and more chances to hear the word they were reaching for.
What the evidence says
A 2006 research review of studies on augmentative and alternative communication (AAC) in people with developmental disabilities found no evidence that AAC decreased speech, and most participants showed some gain. strong
A 2008 systematic review focused on children with autism reached the same conclusion: AAC "does not appear to impede speech production and may result in increased speech production", with the caveat that gains are usually modest and vary between children. strong
A 2021 review that replicated and extended the 2008 one found that, overall, AAC resulted in improved speech production, and noted that when speech did grow it did not overtake the child's use of AAC. strong In plain terms: the device does not become a crutch, and it does not become a cage either. Children use whichever channel works in the moment.
Three reviews across fifteen years, all pointing the same way, is about as settled as this field gets. The honest caveat is size: AAC is not a speech accelerator. It removes a barrier; it does not build the road for you.
Why it helps rather than hurts
- It lowers the stakes. A child who can already ask for water does not have to melt down about it. Calmer children have more attention left for language.
- It gives you something to model. When you press "more" while you say "more", your child sees, hears and can copy. That is how first words are learned in any child.
- It makes communication visible. A symbol stays on the board; a spoken word is gone in a second. Many autistic children process visual information more comfortably.
- It is speech-friendly by design. Devices say the word out loud every time. Your child hears the target word paired with meaning, hundreds of times.
The kinds of AAC, in plain words
| Type | What it looks like | Good for |
|---|---|---|
| Gestures and signs | Pointing, "more", "all done", "help" | Any age, no equipment, works in the bath |
| Picture cards and exchange systems | Handing a card for a wanted item | Concrete requests, early stages |
| Core boards | A laminated board with 20 to 40 everyday words | Modelling while you talk; cheap; goes everywhere |
| Speech-generating devices and apps | A tablet that says the word when pressed | Full language over time; needs an SLP to set up well |
Most families end up with a mix. A good speech-language pathologist (SLP, orthophoniste in Quebec) will choose based on your child's motor skills, vision and interests, not on a rule.
What to do instead of worrying
Model, don't test. The single most useful habit is called aided language stimulation: you point to or press the symbol as you say the word, in real moments, and expect nothing back. "Let's go." "More bubbles?" "All done." Your child watches. Weeks later they reach for it.
Keep talking. AAC is added to speech, never instead of it. Narrate, sing, wait, respond.
Start with words that do work. "More", "help", "stop", "go", "all done", "mine". Not colours, not animals. A child learns a tool that gets them something.
Honour every attempt. If your child signs, points, hands you a card, or presses the wrong button but clearly means something, respond as if it were a sentence. Communication that gets a response gets repeated.
Tell the daycare. Give the CPE a copy of the board and three words to model. Consistency across settings is where the gains come from.
In Quebec
Ask your CLSC for speech-language pathology; it can start through Agir tôt before a diagnosis. official Once your child is followed by the CIUSSS DI-TSA-DP program, ask specifically about AAC assessment. Public waits are long, so if you can afford a few private SLP sessions, spend them on getting a board or device set up and learning to model, then carry it yourself. Confirm any coverage on the official pages before you plan around it. Who does what, including the difference between an SLP and an audiologist, is on Who does what.
Elsewhere in Canada, provincial programs vary; the same principle holds: an SLP sets it up, the parent runs it.
Honest limits
Some children will use AAC as their main language for life, and that is a successful outcome, not a failed one. Some will speak and drop the device. Nobody can tell you in advance which, and a child who has a way to communicate at 3 is better placed for both futures. If your child had words and lost them, that is a separate question for a doctor: see Lost words.
This week
- Choose three words that would make your day easier ("more", "help", "all done") and model each one with a gesture or picture every time you say it.
- Print a simple core board, tape it to the fridge, and press words as you talk. Do not ask your child to use it.
- Call the CLSC (or your current SLP) and ask for an AAC assessment by name.
