RESEARCH
Augmentative and alternative communication (AAC), neurogenic communication disorders, and cognitive disabilities. My research spans the following areas: perception of synthetic speech; effects of voice output communication aids on acquisition and use of graphic symbols by individuals with severe cognitive disabilities; AAC intervention in individuals with aphasia and speech recognition by individuals with dysarthria.
