Our laboratory is working on the topic of speech perception by normal and hearing-impaired listeners. This work also involves basic psychophysical capabilities of normal and impaired listeners. In addition to the theoretical contributions of this work, we also see applications in the design of a new generation of hearing aids and cochlear implants as well as improved speech recognition by machines. Our goals are to identify the types of speech cues that are (mis) perceived by hearing-impaired listeners, as well as to design digital signal processing algorithms to assist their communication abilities.

We have also participated in studies of the human auditory cortex.
