The Speech Research Laboratory

The primary focus of the Speech Research Lab is auditory-visual speech perception (speechreading) in various populations, including adults with normal hearing, adults with hearing loss, and adults with aphasia. Other areas of interest include the acoustics of speech, auditory speech perception by adults with hearing loss, and the development of computer-based training programs for adults with communication disorders.
