Assistive Technologies at the Edge of Language and Speech Science for Children with Communication Disorders

Abstract

About two million individuals in the United States use augmentative and alternative communication (AAC) devices with text-to-speech (TTS) synthesis to speak on their behalf. In this chapter, two specific systems are introduced and evaluated as potentially significant emerging tools for children with communication disorders. The VocalIDTM project was developed to provide unique voices for children who otherwise speak through standard adult voices. Free SpeechTM is an image-based system designed to address grammatical concepts perceived as abstract by children with language disorders. This chapter also reviews the latest developments in electropalatography (EPG): biofeedback technology, which enables the visualization of tongue to palate contact during speech production. SmartPalateTM has developed cutting-edge hardware and software technology to make EPG more intuitive and more accessible in the therapy room and at home.
