Auditory Prosthesis
Laboratory
Li Xu, M.D., Ph.D.
The goal of research in this laboratory is to understand the mechanisms of
hearing and speech perception under electrical stimulation and thus to find
ways to improve speech and music perception in patients with cochlear implants.
We study speech and music perception in patients with cochlear implants and in
normal-hearing subjects using acoustic simulations. Current research projects
include the following areas: (1) spectral and temporal features that contribute
to speech perception and lexical-tone perception, (2) lexical tone development
in children in real-world situations, and (3) nonlinear frequency compression
for Mandarin speech recognition. This laboratory is equipped with the clinical
cochlear-implant programming systems from Cochlear Corporation and Advanced
Bionics Corporation. It also has a sound-attenuating booth and a TDT System 3
for psychoacoustics and neurophysiology experiments. The research in this
laboratory is supported by both internal and external grants.
