The Pitch Extraction of Voiced Speech by the Comparison Between the Original and the Repeated Segmental Waveform.

원 파형과 임의 반복시킨 파형의 비교에 의한 유성음의 피치검출

In speech signal processing, it is necessary to estimate exactly the pitch. We propose a new algorithm which uses the correlation coefficient between the original and the repeated segmental waveform in the frame as a parameter in the pitch extraction. The correlation coefficient in the frame reflects the periodic component and the transient ratio of the waveform.
