摘要：
A new cepstrum model of. segmented speech is presented. Depending on the cepstrum characteristics of the new model, a new speech pitch detection algorithm (LP-CEP), which uses the cepstrum of the LPC predictive residual, is proposed. The method of removing high frequency components is also used for the cepstrum calculation in this algorithm. Simulations showed the pitch extracting results of the LP-CEP are better than that of the Conventional Cepstrum Algorithm (CEP) both for different clean speeches and for different noisy speeches.
