Description
This paper reviews several cepstral analysis techniques for speech signals. These techniques are classified in three classes: the original cepstral method and homomorphic processing techniques; model-based log spectral estimation techniques; and other techniques. First, fundamentals of the cepstral analysis technique is described. Then several model-based techniques which provide unbiased estimators of log spectrum are discussed. They include generalized cepstral analysis and mel-cepstral analysis techniques. Realization of speech synthesis filters for the generalized cepstral and mel-cepstral models are also shown. Finally, LPC derived cepstrum and mel-frequency cepstrum coefficients(MFCC) are briefly explained. Some illustrative analysis examples are shown in the paper.
