Alternative and Augmentative Communication (AAC) refers to different ways people can communicate when they have difficulty speaking or understanding spoken language. It includes methods like using gestures, sign language, communication boards, or special devices called AAC devices. AAC helps individuals who have conditions like autism, speech disorders, or physical limitations to express themselves and understand others. It provides alternative methods to spoken words, augmenting or adding to their communication abilities. AAC can be personalized to fit each person’s unique needs and helps them participate in conversations, share their thoughts, and be understood by others.
A speech-generating device is a special tool that helps people who have difficulty speaking. The person uses buttons, a keyboard, or sometimes even their eyes to pick words or symbols on the device. Once they choose what they want to say, the device turns these choices into spoken words. It’s like having a computer talk for you, making it easier for others to understand what you want to say!
Some devices are “dedicated” – meaning that they cannot be used for any other purpose than AAC. However, common tablets such as iPads or computers can sometimes have the same software as a dedicated device. This is often a much more affordable option.
Most robust AAC devices share some common features. They use synthesized speech. They can be customized. Some use symbols to support communication and others use writing (text to speech). Most are folder-based. They include folders for a variety of things, like food, entertainment, hygiene, and sports.
