[Speech/Voice recognition/combine] sunday

Description: 当把m个信号叠加在一起时，经倒谱分析是能检测出其基频。但倒谱分析主要是用在同态滤波中，可用于某些信号的解褶积。例如提供的语音信号，就能通过倒谱把频谱中的包络和基频频谱分离，-When the m signal superimposed together, by the cepstrum analysis is able to detect its fundamental frequency. However, cepstral analysis is mainly used in homomorphic filtering can be used for the solution of certain signal deconvolution. Such as the provision of the speech signal, we can through the spectrum of cepstral envelope and baseband frequency spectrum separation
