概述如果用传送、记录从话音中析出的特征参数的方法来代替传送、记录原始波形的方法,那末就能比PCM等系统压缩数倍甚至数十倍的信息容量。“PARCOR”型声音分析合成方式作为话音的特征参量就是使用部分自相关系数的新方式。除在声音应答装置中的高效率记录声音等方面得 Overview If the method of transmitting and recording the characteristic parameters extracted from the voice instead of transmitting and recording the original waveform can be compressed several times or even tens of times more than PCM systems, The “PARCOR” sound analysis and synthesis method as a voice feature parameter is a new way to use partial autocorrelation coefficients. In addition to the audio response device in the high-efficiency recording sound and so on
