Introduction to AAC Devices
If your child has difficulty speaking or expressing themselves with words, you are not alone—and there are effective ways to support communication. AAC, which stands for Augmentative and Alternative Communication, refers to tools and strategies that help children communicate when speech is hard, inconsistent, or still developing.
AAC can include simple options, like picture boards or communication books, as well as high-tech devices, such as tablets or speech-generating apps that “talk” when a child selects words or symbols. Some children use AAC temporarily while speech is developing, while others use it long-term as their primary way to communicate.
Importantly, AAC does not prevent speech. Research shows that AAC often supports language development, reduces frustration, and helps children feel understood. When a child can communicate their needs, thoughts, and feelings, behavior often improves because they no longer have to rely on guessing, gestures, or meltdowns to be heard.
AAC is not about replacing your child’s voice—it’s about giving them access to communication right now. Every child deserves a way to say “I want,” “I feel,” “I don’t like,” and “I need help.” AAC provides that bridge, helping children connect, participate, and grow with confidence.
AAC: Low-Tech and High-Tech Communication Options
AAC (Augmentative and Alternative Communication) includes a wide range of tools that help children communicate when speech is difficult or unreliable. These tools generally fall into two categories: low-tech AAC and high-tech AAC. Both are valuable, and many children benefit from using a combination of both.
Low-Tech AAC
Low-tech AAC does not require batteries, electricity, or complex technology. These options are often easy to use, portable, and available at all times.
Examples include:
- picture boards or picture cards
- communication books
- PECS (Picture Exchange Communication System)
- choice boards
- visual schedules
- written words or symbols
- gestures or sign language used as part of AAC
Low-tech AAC is especially helpful for:
- younger children or beginners
- situations where devices are unavailable or overwhelming
- quick communication during transitions or emotional moments
- building early understanding of cause-and-effect (“I communicate → someone responds”)
Low-tech tools are simple, but not limited. They can support meaningful communication, reduce frustration, and help children participate more fully in daily routines.
High-Tech AAC
High-tech AAC includes electronic devices that produce speech or text when a child selects words, pictures, or symbols. These can range from tablets with communication apps to dedicated speech-generating devices.
Examples include:
- tablets with AAC apps
- speech-generating devices
- eye-gaze or switch-activated devices
- devices with voice output
High-tech AAC can:
- allow for more complex language over time
- support sentence building and vocabulary growth
- give children an audible “voice” that others can hear
- be customized to a child’s language level and motor abilities
For many children, high-tech AAC increases independence and social participation, especially in school and community settings.
Using Both Together
Low-tech and high-tech AAC are not an either-or choice. Low-tech tools serve as an essential backup when devices are charging, unavailable, or overwhelming. High-tech devices can expand language and support more detailed communication. Together, they create a reliable communication system across environments.
Most importantly, AAC—whether low-tech or high-tech—does not stop speech. It supports language development, reduces frustration, and helps children feel understood.
AAC is about access. The right tools help ensure your child always has a way to communicate—anytime, anywhere.
