Abstract A serial loading matrix training method is proposed in the factor analysis based speaker recognition. In the loading matrix training process, the eigenvoice matrix, the diagonal matrix(residual) and the channel matrix are calculated serially. In the speaker enrollment process, the above three matrixes are assembled, and then the factors are calculated through the joint factor analysis. Thus, the saturation problem in factor analysis is solved. On the NIST SRE 2006 core test corpus, the equal error rate of the proposed system is 3.65%.
