Dr. Rudnicky has been performing research in the area of speech
since 1975, and has been involved in speech recognition since 1981.
He has done work on the perception of phonetic distinctions, on the
linguistic base of speech perception and on the interaction of speech
perception and reading.  In addition, he has investigated the
acquisition of perceptual skills in reading.

In the area of speech recognition, Dr. Rudnicky has worked on the
problem of lexical access in a knowledge-based speech recognition
system, for which he has developed techniques, both rule-based and
automatic, for modeling phonological phenomena relevant to lexical
access.  He has investigated the use of prosodic phenomena to
supplement phonological modeling in lexical access and has developed
techniques for the automatic detection of contrastive stress in
continuous speech.  Dr. Rudnicky has studied the differences in
human-computer interaction by voice and by keyboard, and is currently
investigating the design of voice-driven interfaces for complex
problem-solving tasks.

Dr. Rudnicky received a B.Sc. in Psychology from McGill University in
1975, a M.S. in Psychology from Carnegie-Mellon University, and a
Ph.D. from the same institution in 1980.  After a year at the
University of Toronto, Dr. Rudnicky joined the faculty at Carnegie
Mellon University, where he is currently a Systems Scientist in the
School of Computer Science and a member of its Speech Group.
