'''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 [[India]], and received his BS degree in [[physics]] (1952) from the [[University of Lucknow]], a diploma in electrical communication engineering (1955) from the [[Indian Institute of Science]], [[Bangalore]] and a PhD in electrical engineering (1968) from [[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 [[National Academy of Engineering]] and [[United States National Academy of Sciences|National Academy of Sciences]], and a fellow of the [[Acoustical Society of America]] and of the [[Institute of Electrical and Electronics Engineers]]. He received the 1986 [[IEEE Morris N. Liebmann Memorial Award]] "for pioneering contributions to linear predictive coding for speech processing", and the 1993 IEEE ASSP Society Award for contributions to linear prediction of speech, multipulse, and code-excited source coding. He is the [[Franklin Institute]]'s [[The Franklin Institute Awards|2003 Benjamin Franklin Medal]] Laureate in Engineering.
