In this paper,A new pitch detection method is proposed by combining mathematics morphology filter and wavelet multiresolution analysis;and pitch period is used as a feature for voiceprint recognition.Combining wavelet multi-resolution analysis and linear prediction cestrum analysis to extract track feature for voiceprint recognition,track feature is an important feature for voiceprint recognition.Based on the research of the feature extraction,a voiceprint recognition system for police scout and judicatory judge is designed.
