Pitch estimation based on harmonic salience

The comb structure formed by the fundamental frequency and its harmonic partials in the spectrum is the important distinction between the pitch and the white noise or other coloured noises. A pitch estimation method based on harmonic salience is proposed which utilises the characteristic mentioned above to enhance the noise immunity and suppress the half-frequency errors and multi-frequency errors effectively. Experiments on various noised data of the TIMIT database demonstrate the robustness compared with other state-of-the art pitch estimation approaches.
