Augmentative and Alternative Communication (AAC) refers to strategies and techniques used by individuals who experience difficulties with communication because they have little or no functional speech. AAC devices can be used for a whole range of difficulties. These could stem from poor hearing, cerebral palsy, or autism, for example. AAC devices can augment speech or provide a replacement for spoken communication. They can also support the development of language and natural speech. We have an international reputation in the development of AAC devices. You will learn to develop technological systems to meet the needs and aspirations of a variety of people, including those with severe speech and physical impairments, and adults with acquired aphasia. Throughout the course you will be interacting with users of AAC devices to get their feedback about what works best for them. We also have links with local speech and language therapists to help you find suitable situations for carrying out your research.
