Pitch Detection of Speech Based on Linear Prediction and Endpoint Detection
A kind of pitch detection algorithm based on linear prediction is proposed in this paper,Aiming at the problem of speech pitch detection is easily affected by additive background noise and resonance peak interference. The algorithm based on wiener filter,gets the predicted residual signal by using the technology of LPC,Then calculates the ACF and AMDF value of the residual signal to estimate the pitch. The results of comprehensive application with ACF and AMDF have obvious improvement than the single ACF and AMDF.
