Bishnu S. Atal
Speech coding innovator
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.
Atal was born in India, and received his BS degree in physics (1952) from the University of Lucknow, a diploma in… More on Wikipedia →
