Noise Whitening-Based Pitch Detection for Speech Highly Corrupted by Colored Noise
Kyung Jin Byun, Sangbae Jeong, Hoi Rin Kim, Minsoo Hahn · ETRI Journal · 2003
Pitch estimation is important in various speech research areas, but when the speech is noisy, accurate pitch estimation with conventional pitch detectors is almost impossible. To solve this problem, we propose a new pitch detection algorithm for noisy speech using a noise whitening technique on the background noise and obtain successful results.
