Bishnu S. Atal (born 1933) is an Indian physicist and engineer. He is a noted researcher in acoustics, and is best known for developments in speech coding. He advanced linear predictive coding (LPC) during the late 1960s to 1970s, and developed code-excited linear prediction (CELP) with Manfred R. Schroeder in 1985.

In 1987, Atal was elected as a member into the National Academy of Engineering for innovative research in the area of linear predictive coding of speech.

Biography

Atal was born in

Brooklyn Polytechnic Institute

.

From 1957 to 1960, he was a lecturer in acoustics at the Department of Electrical Communication Engineering, Indian Institute of Science, Bangalore.

In 1961 Atal joined

Bell Laboratories, where his subsequent research focused on acoustics and speech, making major contributions in the field of speech analysis, synthesis, and coding, including low bit-rate speech coding and automatic speech recognition. He advanced and promoted linear predictive coding (1967), and developed code-excited linear prediction (1985) with Manfred R. Schroeder

.

He retired in 2002 to become affiliate professor of Electrical Engineering at the University of Washington.

Atal holds more than 16 U.S. patents, and is a member of the

2003 Benjamin Franklin Medal

Laureate in Engineering.
