AAC, Communication Devices, and the Modeling Approach That Actually Builds Speech

Published May 12, 2026

What AAC actually is, why it doesn't replace speech (it builds it), how to choose between picture exchange, communication boards, and apps like Proloquo2Go, and how to fund a device through OAP.

AAC and Communication Tools

AAC — Augmentative and Alternative Communication — is the umbrella term for any tool that helps a person communicate when speech alone isn't enough. It includes picture cards, communication boards, sign language, speech-generating devices, and apps on tablets.

Two myths stop families from starting AAC sooner than they should. This guide addresses both, then walks through how to actually start.

Myth 1: "If we give them a device, they'll never learn to talk"

Decades of research and lived experience converge on the opposite: AAC supports verbal speech development, it doesn't replace it.

When a non-verbal or limited-verbal child has a reliable way to communicate, several things happen:

• Frustration drops. Meltdowns reduce. The nervous system has bandwidth to learn other things, including sounds.
• The child experiences their words producing effects in the world (they tap "more" and they get more juice). This is the foundation of language motivation.
• Many children begin to vocalize alongside the device — saying the word as they tap it. This is exactly how speech often emerges.

Children who use AAC and also go on to develop spoken language are common. Children who are denied AAC because parents are waiting for speech to "come on its own" sometimes lose years of communication development that doesn't come back.

Start AAC. It will not stop speech. It might be how speech starts.

Myth 2: "My child isn't ready"

Readiness is much lower than people think. Children as young as 18 months — including those with no spoken words — can use AAC successfully when adults around them model it consistently.

Signs your child is ready (you almost certainly have these):

• Wants things they can't ask for (any pointing, leading, crying for items)
• Recognizes some pictures or symbols
• Tolerates a tablet or paper materials in their hands

If they have any of these, they can start.

The AAC spectrum — from no-tech to high-tech

You don't have to start at the top. Many families work through several levels.

Level 1 — Picture exchange (PECS)

Real, paper picture cards. The child hands the card to you to request the item.

• Cheap. Print at home, laminate, velcro to a binder.
• Slow but very concrete — child physically gives you a picture, you give them the item.
• Common starting point for children new to AAC.
• Some children outgrow it within months; others stay here for years.

Free printable PECS resources: search Teachers Pay Teachers for "PECS communication" — many free downloads. Autism Little Learners has free printable boards.

Level 2 — Communication boards

A laminated page or wall-mounted board with multiple pictures organized by category. Child points to what they want.

• More vocabulary than PECS without needing a device.
• Useful in specific environments — by the kitchen, in the bathroom, in the car.
• "Core word" boards (yes, no, more, stop, help, all done, want) cover most early communication needs.

Level 3 — Single-purpose talking devices

Buttons or recordable cards with a few pre-recorded messages.

• Less common now that tablets are cheap.
• Still useful for very young children or specific situations.

Level 4 — Tablet-based AAC apps

This is where most modern AAC lives. The tablet is loaded with an app that generates speech when the child taps icons.

Proloquo2Go is the most-recommended app in the autism community:

• Apple-only (iPad).
• Tied to your Apple ID — once purchased, works across all iPads on the same ID.
• Goes on sale during the AssistiveWare AAC sale (typically October).
• Highly customizable — you can build vocabulary that matches your child's life.

Other apps used by some families:

• TouchChat — Apple-only, similar to Proloquo2Go.
• LAMP Words for Life — different organizational approach (motor planning), preferred by some SLPs.
• CoughDrop — cross-platform (Apple, Android, web).

If you have an iPad, Proloquo2Go is the safest first choice. If you're starting from scratch, an iPad + Proloquo2Go is what most families converge on.

Level 5 — Dedicated speech-generating devices

Purpose-built devices (Tobii Dynavox, NovaChat, etc.) — not tablets, no other apps.

• Required by some school boards for in-class use because they can't be locked down to "AAC only" the way a generic tablet sometimes needs to be.
• Often funded by OAP or Assistive Devices Program (ADP) once an SLP recommends one.

For most families, an iPad with Proloquo2Go is sufficient and more flexible.

Funding an AAC device through OAP

If your child is registered with OAP and has been recommended an AAC device by an SLP:

1. Get the SLP's written recommendation. This is typically the trigger.
2. The SLP submits the recommendation to your OAP coordinator.
3. Approval covers the device (or app, in the case of Proloquo2Go) and sometimes a case/mount.
4. You purchase, submit the receipt, get reimbursed.

Without OAP funding, the cost of starting:

• iPad (used or refurbished): $200–400
• Proloquo2Go: ~$250 USD (often less on sale)
• Sturdy case with handle/strap: $30–80
• Optional: kid-friendly stand, screen protector

Total under $700 for a setup that can carry a non-verbal child for years.

Modeling — the part everyone gets wrong

The single most important practice in AAC: the adults model the device too.

Modeling means: when you say something to your child, you also tap the words on the device.

• "Time for snack" — you tap "snack" on the device as you say it.
• "Want more?" — you tap "more" as you ask.
• "All done with bath" — you tap "all done" as you say it.

Why this works:

• The child hears the word and sees the symbol simultaneously, repeatedly.
• They learn the device by watching, just like typical kids learn speech by watching.
• They see that the device is for communication, not just for asking for things.

How much modeling:

• Aim for at least 50% of your child's interactions in early stages. Yes, that's a lot.
• It's exhausting at first. It becomes habitual within weeks.
• Adults who model heavily see vocabulary growth in their child within 2–3 months.

Adults who don't model — who hand the child a device and expect them to use it spontaneously — typically don't see much progress. The device doesn't teach itself.

What to load on the device first

A common mistake is starting with hundreds of pictures and overwhelming the child.

A reasonable starter set (most apps come pre-loaded with similar vocabulary):

Wants:

• More
• All done / finished
• Help
• Want
• Yes / no

Activities:

• Eat / drink
• Play
• Watch (TV, iPad)
• Bath
• Sleep
• Outside

Specific items (customized to your child):

• 5–10 favourite foods
• 3–5 favourite toys/shows
• Family members (Mom, Dad, sibling names)
• Familiar places (school, park, grandma's)

Feelings:

• Happy, sad, mad, scared, tired

Add vocabulary as your child uses what they have. Don't pre-load everything — the larger the vocabulary, the harder it is to find what you need.

Functional Communication Training (FCT)

A specific technique used by behaviour analysts: replacing meltdowns or aggression with a communicative response.

If your child melts down to escape a task, they're communicating "I want to stop." FCT teaches them to instead tap "all done" on the device. The same need is met with a non-disruptive behaviour.

This is one of the highest-leverage uses of AAC and one of the fastest ways to reduce challenging behaviours. Ask your BCBA / RBA about it specifically.

Sign language as a complement

Sign language and AAC aren't either/or. Many families use both:

• Sign for fast, hands-free communication (ASL or Makaton-style simplified signs).
• Device for fuller sentences, less common requests, communication with people who don't know sign.

Common starting signs (most autistic children learn these within weeks if modeled): more, all done, eat, drink, help, please, yes, no, stop, mom, dad. YouTube has free tutorials in any sign system.

At school

Once your child has a device, school cooperation is the next mountain.

• Bring it every day. Send it back and forth in the backpack. The device only works if it's where the child needs it.
• Train the team. Provide a one-page cheat sheet for the EA and teacher: how to model, what core words to use, what your child uses the device for.
• Insist it stay with the child. Some schools will store the device in a cabinet "for safety." That's an enormous mistake — communication tools must be available at all times.
• Get the SLP involved. School SLPs can support AAC implementation. Ask the SERT to engage them.

If your school resists ("we don't have time to learn the app"), escalate. Communication is a fundamental right and the school is required to support your child's accommodations.

Realistic expectations

• The first month is awkward. The child may ignore the device. Adults may forget to model. Push through.
• Months 2–3 usually show first independent use — a child taps "more" without prompting.
• Months 4–6 show vocabulary expansion and combining words.
• 6–12 months in, the device becomes part of how the family communicates.

Children who are using AAC at one year typically retain that skill for life and continue building. There's no upper limit; AAC users have gone on to write essays, give speeches, attend university.

What every AAC family eventually learns

• Don't wait for "ready." Start.
• Model more than you think you need to.
• Make the device available at all times — meals, bath, bed, car, school.
• Don't use it as a reward or take it away as punishment. It's their voice.
• Their first independent word on the device will make you cry. That's normal.

You're giving your child a voice. There is almost nothing more important in autism parenting than this.
