The influence of fundamental frequency to performance of speaker recognition using MFCC
Wei Lu, Beiqian Dai, Hui Li, Qingsong Liu · 2009
Fundamental frequency can affect the accurate description of MFCC and degrade the performance of speaker recognition system,so a new parameter called SMFCC(smoothing MFCC) was proposed.The parameter mainly employs the method of smoothing amplitude spectral to reduce the effect of fundamental frequency.Experiments in YOHO speech database show that SMFCC is more effective and robust than the conventional MFCC,especially in the female speaker recognition system.
