| 摘 要： | 给出了一种基于广义线性区分核支持向量机方法的VolP说话人确认算法，给出了直接从G．729，G．723．1（6.3Kb／s）和G．723．1（5．3Kb／s）压缩语音的码流中提取识别参数，采用广义线性区分核的支持向量机进行确认的方法。实验结果表明，该方法可有效地进行VoIP说话人确认。

| Abstract: | A speaker verification method is proposed for compressing speech of VoIP. In this method, identification parameters are extracted directly from the bit streams of G.729 or G.723.1 (5.3/6.3 Kb/s), and then SVM(Support Vector Machine) using GLDS(Generalized Linear Discriminate Score) is adopted. Experiment shows that it is an effective method for VoIP speaker verification. |
