Getting started

When Should a Nonverbal Child Start Using AAC?

VOIS Team · 10 August 2026

Parents often ask when a child is "ready" for AAC.

Sometimes the question comes up in a therapist's office. Sometimes it happens later that evening, when a parent searches online because they are still wondering whether starting AAC too early could somehow do more harm than good.

The good news is that a child does not have to pass a test before they can start using AAC.

There is no perfect age to start AAC

In the past, some children were expected to show certain skills before AAC was considered. They might have been asked to recognise pictures, understand cause and effect or demonstrate a certain level of attention first.

Current AAC practice has moved away from that approach.

A child does not need to prove that they can communicate before being given more ways to communicate.

AAC can be introduced alongside developing speech, and it can include much more than an app or device. Pictures, photographs, gestures, communication boards and speech-generating systems can all form part of AAC.

The right starting point depends on the child.

Signs it may be worth exploring AAC

There is no single sign that automatically means a child needs AAC, but it may be worth speaking to a speech-language therapist if:

• your child has difficulty communicating what they want, need or feel;
• people outside the immediate family regularly struggle to understand them;
• communication breakdowns often lead to frustration;
• your child relies heavily on pulling an adult towards something, crying or behaviour to get a message across;
• spoken communication is limited or unreliable across different situations.

These signs are not a diagnosis. Children develop differently, and communication difficulties can have many causes.

They are simply reasons to look more closely rather than waiting indefinitely for speech to develop on its own.

AAC does not have to be a last resort

One of the biggest misconceptions about AAC is that it should only be introduced after speech has "failed."

In reality, AAC can support communication while speech and language are still developing.

Imagine a child needs help opening a snack. Without an easier way to communicate, they may cry, push the container towards someone or become frustrated. With AAC, they may be able to indicate help.

That small interaction matters. The child has communicated an idea, someone has understood it, and their message has produced a response. They are learning something very important: communication works.

AAC does not have to replace speech. It can support speech, supplement it or remain part of a person's communication long term.

The goal is not to choose between AAC and speech. The goal is communication.

What starting AAC can look like

Starting does not have to mean placing hundreds of unfamiliar words in front of a child. It can begin with words and images that make sense in everyday life.

That might include:

• more
• help
• stop
• go
• finished
• mum
• dad
• a favourite toy
• a favourite food

Children also need opportunities to communicate for reasons other than requesting things. They may want to say no, ask for help, comment on something, make a choice or get someone's attention.

For some children, photographs are a useful place to begin because they connect directly to the people, objects and routines they already know. A photograph of their own cup or favourite toy may be easier to understand than an unfamiliar symbol.

Show your child how AAC works

Giving a child an AAC system is only one part of the process.

They also need to see other people using it.

Instead of repeatedly asking, "What do you want?" or "Show me," parents and communication partners can model words naturally during the day. You might say, "Let's go," while pointing to or selecting go. If something will not open, you might model help. When an activity ends, you might model finished.

There does not need to be pressure for the child to copy you straight away. The aim is simply to show that the words, pictures or buttons have meaning.

Where VOIS fits in

VOIS was designed to make this kind of everyday communication easier to build at home, in therapy and at school.

Families can create communication cards using their own photographs and record words using a familiar human voice and the language spoken in their home.

That means Gran can actually be a photograph of Gran, a favourite snack can be the one the child recognises from the kitchen, and the voice they hear can be one they already know.

VOIS is not a replacement for a speech-language therapist, and families do not need an app before they can begin supporting communication. It is simply a tool designed to help make AAC more personal, familiar and practical.

Should you still see a speech-language therapist?

Yes, where possible.

A speech-language therapist can assess how your child currently communicates, what they understand, their motor and sensory needs, and which type of AAC may suit them best.

Starting some communication support at home and getting professional advice do not have to be separate things. You can do both.

You do not have to wait for the perfect moment

Parents can spend a long time worrying about whether they are introducing AAC too early.

A more useful question may be: does my child have a reliable way to tell other people what they want, need, think and feel?

If the answer is no, or only sometimes, it may be worth exploring additional communication support.

AAC does not mean giving up on speech. It does not predict how your child will communicate in the future. It simply gives them another way to be heard.
