Li-Ming Zhao · Control Engineering of China · 2004
Detection of voiced regions in speech is an important process in many applications. A new algorithm based on wavelet transform and Teager energy operator (TEO) is presented to detect voiced regions. Experiments are performed to evaluate the accuracy and robustness of the proposed algorithm by using the clean speech and speech contaminated with white Gaussian noise. The results show that the proposed algorithm can accurately detect voiced regions and possess the robustness to white Gaussian noise.
