Pitch frequency is the fundamental frequency of a speech signal. It is one of the most important parameters for speech signal processing. The simulated results on Keele pitch reference database show that the performance of the proposed wavelet transform based pitch detection algorithm is obviously better than the original AMDF and its improvements based algorithms.
