Pitch detection of nosy speech signal based on Bark wavelet transform
Zhao Heming, Zhu Qi, YU Yi-biao, Chen Xueqin · 2003
On the basis of psychological acoustic theories and experiments, this paper introduces the concept of Bark wavelet, and applies it to pitch detection of noisy speech signals. Experimental results obtained indicate this method is more suitable for noisy speech signals than the classical pure autocorrelation method.
