	Research Interests Basic research interests focus on the perception of speech and complex, non-speech sounds. Recently the psychophysical thresholds for vowels have been investigated for both normal-hearing and hearing-impaired populations. Auditory models of speech processing have been reasonably successful in explaining the results of these experiments. A second area of research has invesitigated the principles and techniques for developing computer-based speech training aids. Facilities The Speech Psychophysics Laboratory has a network of 10 experimental PC systems, 5equipped with TDT hardware for psychophysical research. Software includes speech analysis and synthesis programs as well as data analysis packages and MATLAB. Additional facilities for digital recording and workstations for digital signal processing are available.  Teaching Responsibilites/Interests At the undergraduate level I teach speech acoustics including speech perception and speech production, a mathematics course for speech and hearing students, and a new speech technology course.. In the graduate program I teach courses in digital signal processing as well as one core and one advanced seminar on the acoustics of speech in developing and disordered populations.
