Raj Reddy’s work on efficient algorithms gave rise to modern speech recognition systems, demonstrating speaker independence and a capability of handling a large vocabulary. Dr. Reddy, currently Mozah Bint Nasser University Professor of Computer Science and Robotics in the School of Computer Science, Carnegie Mellon University, Pittsburgh, Pa., has been a member of the faculty since 1969. The Sphinx recognition system, which serves as the basis of commercial speech recognition systems found today in automated phone centers, and computers and robots that respond to a user's voice, was developed under Dr. Reddy’s guidance. An IEEE Fellow, he holds ten honorary doctorates and is the recipient of the 1994 Association for Computing Machinery Turing Award. Dr. Reddy is former president of the American Association for Artificial Intelligence.
