【 摘 要 】

In view of the characteristics of speech signals, dullness in speech has obvious periodicity characteristics, and dullness is only quasi periodic. So we use short time averaging to estimate pitch period. In view of these characteristics, the speech signal processed in this paper is grouped according to the frequency, and then the pitch period is extracted after grouping, which reduces the complexity and accuracy of the processing.
