  • Abstract
    This paper describes multi-pulse speech coding with pitch prediction. Two realization approaches to the coding, which differ in regard to pitch predictor, are described. Coding performances for the two approaches are evaluated objectively and subjectively. The introduction of pitch prediction to a multipulse coder shows 2-3 dB SNR (Signal to Noise Ratio) improvement, and perceptually annoying noise is reduced over a conventional coder without pitch prediction, at bit rates above 8 kbps.
