My work is on speech analysis, speech processing, and speech synthesis
to aid persons with speech and hearing-related disabilities. Our
ModelTalker project is directed toward the development of high quality
text to speech synthesis using natural speech (primarily diphone)
concatenation units. Our STAR (Speech Training, Assessment, and
Remediation) project aims to develop a video game like speech training
system which uses speech recognition to assess the speech of young
children and animated cartoon characters to provide feedback and keep
children involved in the game. Much of this work is heavily
application oriented and uses established speech processing methods in
new applications. However, basic research in areas like speech
disorders, speech perception, acoustic phonetics, and speech
processing remains an important component of our work in the Speech
Some of the projects that I and other people in my lab are working on right now are:
