Summary

Bishnu S. Atal is an Affiliate Professor in the Electrical Engineering Department at the University of Washington, Seattle, WA. He retired in March 2002 after working for more than 40 years at Bell Labs and AT&T Labs.

He joined Bell Laboratories, Murray Hill, New Jersey in 1961 and worked there until 1996. He was a Technology Director at the AT&T Shannon Laboratory, Florham Park, New Jersey, from 1997 to 2002. He was made a Bell Laboratories Fellow in 1994 and an AT&T Fellow in 1997.

He is a Fellow of the IEEE, and Member of the United States National Academies of Science and Engineering.

His past research centered in the fields of acoustics and speech processing covering a wide range of topics. He is internationally recognized for his many contributions to speech analysis, synthesis, and coding. His pioneering work in linear predictive coding of speech established linear prediction as one of the most important speech analysis technique leading to many applications in coding, recognition and synthesis of speech. He invented multipulse linear predictive coding and code-excited linear prediction (CELP) which have found widespread applications for efficient transmission of speech in telephone networks. His research work is documented in over 100 technical papers and he holds 17 U.S. and numerous international patents in speech processing.
