TREATMENT METHOD FOR MEASURING autocorrelation function of the pitch of the speech signal

摘要

1. A method of processing the autocorrelation function to measure the pitch of the speech signal, characterized in that produce underline the main peak of the autocorrelation function of the signal period, the autocorrelation function is subtracted from the received signal segment, a lower amplitude of the autocorrelation function signal for the module on the same segment and nullify the negative raznosti.2. A method according to claim 1, characterized in that perform additional smoothing of the autocorrelation function obtained for a signal module.
