AAC, Gestures, and Signs: Supporting Communication Before Speech

For many parents, one of the biggest concerns is when their child isn’t speaking yet. It can bring up questions, worries, and often a lot of conflicting advice. One common myth that continues to come up is the idea that using gestures, signs, or AAC (Augmentative and Alternative Communication) will delay a child’s speech.

The reality is quite the opposite.

Supporting communication in different ways doesn’t replace speech, it gives children a way to communicate while they continue developing language skills. Research consistently shows that AAC does not prevent speech development, and for many children, it supports language learning alongside spoken language.

What Is AAC and Alternative Communication?

Communication is much more than spoken words. It includes gestures, facial expressions, pointing, signs, pictures, and communication devices.

AAC (Augmentative and Alternative Communication) refers to any method that supplements or provides an alternative to spoken language. AAC can include:

• Simple gestures like pointing, reaching, or waving

• Sign language

• Picture boards or communication books

• Speech-generating devices

  
  

These tools give children a way to express their needs, thoughts, feelings, and ideas, even if spoken language is still developing.

Myth: “If My Child Uses Signs or AAC, They Won’t Talk”

This is one of the most common concerns parents have.

Research consistently shows that using AAC, gestures, or signs does not prevent speech development. Many children develop spoken language alongside AAC, and some use more spoken language after AAC is introduced.

Having a reliable way to communicate allows children to participate in conversations, hear language models, and experience successful communication. These everyday interactions help build language skills and encourage communication in all forms, including speech when a child is ready.

When children have a way to communicate:

• They experience less frustration.

• They engage more with others.

• They learn that communication has meaning and power.

This often leads to more frequent communication attempts and richer interactions with the people around them.

Why Early Communication Matters

Before children can speak, they first learn that communication is a two-way interaction. They discover that:

• Their actions can get a response.

• They can express wants, needs, and ideas.

• They can share interests and experiences with others.

• Communication helps them connect with the people around them.

Gestures, signs, and AAC tools help build these early communication skills. They allow children to participate in meaningful interactions while their verbal skills continue to develop.

For some children, AAC serves as a bridge while spoken language develops. For others, it becomes their primary way of communicating. In both cases, the goal is effective communication and meaningful connection.

How to Support Communication at Home

You don’t need to wait for words to begin supporting communication. Here are a few simple ways to help:

Model gestures and signs Use simple gestures like waving, pointing, or signing “more” and “all done” during daily routines.

Pair words with actions When you say a word, show it. For example, say “drink” while pointing to a cup or offering it.

Respond to all communication attempts Whether it’s a look, a sound, or a gesture, or pointing to a picture, respond as if your child is communicating something meaningful. This helps them learn that their communication has an impact.

Create opportunities to communicate Pause during routines, hold items slightly out of reach, or offer choices to encourage your child to express what they want or need.

Remember that communication isn't just about requesting. Children also communicate to greet others, protest, comment, share excitement, ask questions, and connect with the people around them. Encourage and celebrate all of these communication attempts.

When Additional Support Can Help

If your child is not yet using words, gestures, or other forms of communication consistently, it may be helpful to seek guidance.

Speech therapy can support children in building both verbal and non-verbal communication skills. For some children, introducing AAC or other communication supports early can reduce frustration, increase participation and create more opportunities for language learning.

Families exploring speech therapy in Toronto or the GTA often wonder if a referral is needed or how to get started. Private speech therapy services do not require a referral, and many options are available in-clinic, in-home, or virtually to fit your family’s needs.

Communication Comes First

Spoken language is just one way people communicate. The goal is not just talking, it’s being able to express thoughts, needs, feelings and ideas while connecting with others.

When children feel understood and have a reliable way to communicate, they build confidence, reduce frustration, and become more engaged with the world around them. Every successful communication interaction helps support their overall language development.
