Augmentative and Alternative Communication (AAC) gives children a reliable way to communicate when speech alone does not meet their needs. AAC can include gestures, signs, pictures, communication boards or speech-generating devices, and it can be used alongside spoken language. For a child who struggles to communicate what they want, feel or think, having another way to express themselves can change everyday interactions at home, school and with friends.
What Is AAC and Why Does It Matter?
Communication is much more than asking for food, toys or help. Children need to say “no”, make choices, ask questions, share experiences, express emotions and join conversations.
When spoken communication is difficult, these ordinary interactions can become frustrating. A child may point, pull an adult towards something, repeat sounds or become upset because the message is not getting through.
AAC provides another route. Importantly, there is no single AAC system that works for every child. Some children use signs or pictures, while others may benefit from a communication book or speech-generating device. The right approach depends on the child’s communication abilities, motor skills, sensory needs and everyday environments.
1. AAC Gives Children More Control Over What They Communicate
One of the biggest benefits of AAC is that it gives children more opportunities to express themselves independently.
A child can communicate that they want another turn, do not like something, need help or have finished an activity. These may seem like small messages, but being able to communicate them without relying on an adult to guess can make a significant difference.
AAC should therefore provide vocabulary for more than requesting. Children need words and symbols for refusing, commenting, asking, describing, greeting and sharing information as well.
2. AAC Can Reduce the Frustration of Being Misunderstood
Repeated communication breakdowns can be exhausting for a child.
Imagine knowing what you want but having no reliable way to explain it. When an adult guesses incorrectly several times, frustration can quickly build.
AAC gives children a way to repair these situations. Being able to communicate “help”, “stop”, “different”, “finished” or “I don’t know” can give adults information that might otherwise be difficult to understand.
3. AAC Can Support Language Development
Many parents worry that introducing AAC will stop their child from learning to speak. Current professional guidance does not support this concern, and AAC can be used alongside spoken language to support communication and language development.
For example, an adult might say “more” while pointing to the symbol for more. The child hears the spoken word, sees what it represents and has a way to communicate the same idea.
This gives children more opportunities to understand and use language throughout the day.
4. AAC Helps Children Participate Socially
Being able to communicate a need is only one part of communication. Children also need ways to join in.
They want to greet their friends, answer questions, tell someone about their interests, choose a game and make comments during play. Without an effective communication system, a child may understand what is happening but have limited opportunities to contribute.
AAC can expand those opportunities at home, school and in the community.
For example, a child might use AAC to tell a friend which game they want to play or tell a teacher they need help. Professional guidance recommends that AAC be available across the environments where children communicate, rather than being restricted to therapy sessions.
5. AAC Builds Independence Through Choice
Communication and independence are closely connected.
When adults have to interpret a child’s needs, they inevitably make many decisions for them. A reliable communication system allows children to make choices themselves.
That could mean choosing what to wear, rejecting an activity, asking for a break or telling someone what they want to do next.
These everyday decisions give children opportunities to practise autonomy. Over time, being able to communicate preferences and make choices can support greater participation in family routines, school activities and social situations.
The AAC system itself also needs to be accessible. A child may understand exactly what they want to communicate but struggle to physically select a symbol because of motor or positioning difficulties. This is one area where a children’s occupational therapist may contribute to a wider multidisciplinary approach by considering access, movement, positioning and functional participation.
Giving Children More Ways to Be Heard
AAC is not about replacing speech or choosing the most advanced device. It is about giving a child a communication method they can access and use meaningfully to express themselves, participate with others and make choices. When communication becomes more accessible, children have more opportunities to show what they know, build relationships and become increasingly independent.
Supporting Your Child
If your child has difficulties with communication alongside motor, sensory or functional challenges, an occupational therapist can contribute to understanding the barriers affecting participation.

FAQ
What are the benefits of using an AAC device for children?
AAC can help children express needs, feelings, ideas and choices while reducing communication breakdowns and supporting social participation. It can also complement spoken language rather than preventing speech development.
What should be the primary goal of AAC?
The primary goal is functional communication that allows a child to express themselves, interact with others and participate in everyday activities. The focus should be on what the child needs to communicate rather than on using a particular device.
What is the best age to start AAC?
There is no minimum age for introducing AAC and children do not need to meet specific cognitive, language or developmental prerequisites. It can be considered whenever a child’s existing communication does not adequately meet their needs.
