代码说明：

为了满足数字通信及其它商业应用的需求，语音压缩编码技术得到了迅速发展。介绍了目前语音压缩编码技术的研究进展，主要包括连续可变斜率增量调制(CVSD)、小波分析、多脉冲激励线性预测编码、散布脉冲码激励线性预测(DP-CELP)、多重脉冲散布非均匀代数码本激励线性预测(MPD-USACELP)、波形内插(Ⅷ)、线谱对(频率)(LSP)的量化(In order to satisfy deman凼of the digital communication and other commercial applicatiOils， the speech compression technology has been developed rapidly．The present research progress in speech compression technology is introduced in this paper including CVSD， wavelet analysis and its application to speech coding，MPLPC，DP-CELP，MPD-USACELP，Ⅷand quantification of LSF．These algorithins)
