Abstract
This paper describes the principle of MFCC voiceprint feature extraction,MFCC feature extraction mode,and implementation based on MFCC voiceprint recognition.The extraction mode includes the MFCC extraction process,short-time Fourier transform(STFT),the construction of Mel filter banks,discrete cosine transform(DCT),and the extraction of MFCC feature values.Propose an improvement plan to address the shortcomings of separability and robustness in the fusion feature extraction scheme.
