Abstract: This study proposes a Verification-Mode voice recognition system which uses in IC card. Improvements have been made both in the two periods of voice recognition: on the one hand, a new method of endpoint detection is used in voice pretreatment and doing cepstrum filtering for coefficients in the MFCC extraction; on the other hand, use UBM-GMM algorithm in the process of template matching and make it better to the verification mode. Experiment with putting the user’s voice data into IC card to do the user verification and the result shows that this mode eliminates the dependence of voice text and improve the speed and precision of the identification.
