- Fellow, Acoustical Society of America, 1993
Awards
Edward Sapir Award from the New York Academy of Sciences for the best dissertation in Linguistics, 1981
Research Interests
- Psychophysical studies of speech and complex, non-speech
sounds with normal and impaired listeners
- Auditory models of speech processing
- Computer-based speech training aids for improving disordered speech and for
reducing foreign accent
- Microcomputer applications of voice input/output for communication disorders
Facilities
The Speech Acoustics Laboratory has a network of five
experimental PC systems equipped with TDT hardware for
psychophysical research. Software includes speech analysis
and synthesis programs as well as data analysis packages.
Additional facilities for digital recording and workstations
for digital signal processing are available.
