Augmentative and Alternative Communication

Communication is fundamental to being human. Augmentative and Alternative Communication (AAC) systems and devices assist people with little or no functional speech to communicate. Dundee research on pragmatics and conversational modelling to improve communication rates and support conversational flow has led to widespread use in AAC of re-usable phatic conversation (e.g. greetings, responses, farewells) and visual scenes (rapid access to conversational items). More recently, the application of natural language generation and sensor-based data-to-text technology has resulted in the automated generation of jokes and narratives to assist non-speaking people to engage in lively conversation. Symbolic and phonetic interfaces have been developed for children and adults with congenital and language impairments. AAC research at Dundee is user-led with strong connections with clinical practitioners, end-users and industry, identifying ways in which innovative technologies can support extra-ordinary communication.
