| Abstract(in English) | This paper presents the experimental comparison of a speaker recognition system based on Gaussian Mixtures Model (GMM) by reinforcing and enhancing the feature vector characteristics. The baseline system proposed use a GMM with 8 gaussian mixtures with diagonal covariance matrix and for feature vector the LPC-cepstrum coefficients are used. One system is developed to improve the recognition rate by using only voiced part to extract the LPC-cepstrum coefficients. Other system is made reinforcing the feature vector LPC-cepstrum with pitch information. The system is compared with the system enhanced by the feature vector LPC-cepstrum with Cepstral Mean Normalization (CMN). The experimental comparisons of those systems are evaluated in closed and open test using speech data with time difference. |
