4kb /s低速率话音编码是近年来话音信号处理研究的重要课题 ,也是ITU T下一步标准化的目标 ,本文讨论了由Comsat公司提出的采用谐波激励线性预测(HE LPC ,HarmonicExcitationLPC)技术实现 4kb /s速率低速声码器的原理。
4kb / s low-rate voice coding is an important issue in the research of speech signal processing in recent years. It is also the goal of next ITU-T standardization. This paper discusses the application of HE LPC (HarmonicExcitationLPC) technology proposed by Comsat Company to achieve 4kb / s rate low-speed vocoder principle.
