WANG Du-sheng, TIE Man-xia, FAN Chang-xin. A Real Time Pitch Detection Algorithm for Speech Signal[J]. Acta Electronica Sinica, 2000, 28(10): 9-11.DOI:
A real time pitch detection scheme is proposed in this paper in order to reduce the delay of the existent pitch detection algorithms. The experimental results show that the new scheme can obtain exact pitch level within the current frame and reduce the delay of the existent auto-correlation pitch detection algorithms using smooth processing.
