摘要：

An effective pitch period detection method combining Teager energy operator (TEO) with spatial correlation function is proposed. A voiced regions detection (VRD) algorithm based on lifting wavelet transform and Teager energy operator is proposed firstly. Then, an algorithm based on spatial correlation function for estimating pitch frequency only in voiced regions is presented. Experiments show that the proposed algorithm has a better robustness and more precision compared with the classical wavelet-based methods and auto-correlated function (ACF).
