SPEAKall! was developed by the Purdue University EPICS Department as an application designed to help children with special needs learn the process of constructing sentences. This app specifically targets children with severe communication disorders who need intervention in the area of augmentative and alternative communication (AAC). It can be used within an exchanged-based communication approach. The app is fully customizable to each child’s specific needs by allowing the instructor to use recorded audio and custom images from any library. When working with the application use graphic symbol sets and systems designed for AAC users to obtain the best results.
