AAC Devices: What They Are and How They Can Help Your Child Communicate
Communication is a fundamental human need. But for many children with speech delays, autism, or apraxia, verbal speech may not come easily—or at all. This is where augmentative and alternative communication (AAC) devices come in.
AAC devices provide a way for non-verbal or minimally verbal children to express their needs, thoughts, and feelings. Many parents worry that introducing an AAC device will discourage verbal speech, but research shows the opposite: using AAC enhances a child’s ability to communicate and can even support speech development.
If you’re new to AAC, don’t worry. In this blog, we’ll break down what AAC devices are, how they work, and how to effectively use them to help your child communicate.
What Is an AAC Device?
AAC stands for Augmentative and Alternative Communication. These tools are designed to support or replace verbal communication. AAC devices come in many forms, from simple picture boards to high-tech speech-generating devices.
Types of AAC Systems
There are different types of AAC Systems: No-Tech, Low-Tech, Mid-Tech, and High Tech:
1. No-Tech
Gesture-based communication (e.g., pointing, nodding)
2. Low-Tech AAC
Core vocabulary boards
Communication books or charts
3. Mid-Tech AAC
Simple leveled speech generating devices
4. High-Tech AAC
Speech-generating devices (SGDs) like iPads or tablets with communication apps
Dedicated AAC devices with customizable buttons and voice output
Eye-tracking communication systems for children with motor difficulties
Regardless of whether a system is low-tech or high-tech, the goal is the same: to give children a way to communicate when verbal speech is not yet available.
Common Myths About AAC Devices
Many parents hesitate to use an AAC device due to misconceptions about how they impact speech development. Here are some of the most common myths—debunked.
Myth #1: “If my child uses an AAC device, they’ll never learn to speak.”
💡 Reality: Research shows that AAC actually encourages verbal speech. Many children begin speaking after using an AAC device because it reinforces language processing and gives them a way to practice communication before their speech muscles are fully developed.
Myth #2: “AAC is only for kids who will never talk.”
💡 Reality: AAC devices are beneficial for children with temporary speech delays as well as those who may remain non-verbal. Even children who eventually become verbal can use AAC devices as a stepping stone to full speech.
Myth #3: “My child is too young to use AAC.”
💡 Reality: Children can start using AAC devices as early as infancy. Just like verbal language development, communication with AAC follows a natural progression. The earlier you introduce it, the better.
Myth #4: “AAC is too complicated for parents to use.”
💡 Reality: Learning to use an AAC device takes practice, but it doesn’t have to be overwhelming. By starting with just a few words or pictures and gradually increasing vocabulary, both parents and children can become comfortable with the system.
How to Use an AAC Device Effectively
Simply handing your child an AAC device won’t automatically lead to communication. Just like learning verbal speech, children need consistent modeling and practice to use AAC successfully.
1. Model the Use of the Device
Your child will learn by watching you. Just as you naturally speak to them every day, you should also use their AAC device to model communication.
For example: If your child points to a toy, tap the “play” button on the device and say, “Play! You want to play!”
2. Start with Core Vocabulary
Focus on a small set of core words like “want,” “go,” “more,” and “help.” These are words that can be used in many different situations, making them a strong foundation for communication.
3. Encourage and Praise Communication Attempts
Every time your child makes an effort to use their AAC device, celebrate it! Even if they select the wrong word or don’t use the device as intended, the key is to reinforce the idea that communication is valuable.
4. Keep the Device Accessible
Make sure your child has access to their AAC device at all times. If it stays on a shelf, they won’t learn to use it naturally. Instead, treat it like an extension of their voice—keep it nearby during meals, playtime, and daily routines.
5. Work with an SLP Experienced in AAC
A speech-language pathologist (SLP) with AAC expertise can guide you in setting up the device, selecting the right vocabulary, and ensuring your child gets the most out of their communication system.
Why AAC Devices Are a Game-Changer for Kids
At Infinity Motor Development Center, we’ve seen firsthand how AAC can unlock a child’s ability to communicate. Some children arrive at our clinic unable to express their needs, leading to frustration and behavioral challenges. Once they begin using an AAC device, their world opens up. They can share their thoughts, ask for what they want, and engage more fully with family and friends.
AAC is more than just a piece of technology—it’s a bridge to connection and self-expression.
Is an AAC Device Right for Your Child?
If your child struggles with verbal speech, an AAC device may be a helpful tool. Every child is unique, and finding the right communication method takes time. But with the right support and consistency, AAC can help your child find their voice—whether through words, symbols, or gestures.
