Research interests

Speech perception by hearing-impaired listeners, especially cochlear implant users; perception of talker-specific properties of speech by cochlear implant users, perception of suprasegmental speech characteristics and its relation to learning words; psychoacoustic abilities of cochlear implant users and of persons with unilateral hearing loss.

Dr. Uchanski collaborates closely with Drs. Lisa S. Davidson and Jill B. Firszt.
