| 摘 要： | 在基于因子分析的说话人识别中,提出串行训练载荷矩阵的方法.在载荷矩阵训练中,采用串行的方式训练得到说话人因子矩阵、对角阵(残差矩阵)和信道空间矩阵.在说话人注册中,将以上3个载荷矩阵拼接,采用联合估计的方法得到每个说话人的因子.采用这种策略可有效解决因子分析中的饱和问题.在NIST SRE 2006年核心测试数据库上等错误率能达到3.65%.

| 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 propose... |
