| 摘 要： | 提出一种基于主成分分析（PCA）和多约简支持向量机（SVM）的多级说话人辨识方法。首先用PCA对注册说话人进行快速粗判决，再用多约简SVM进行最后决策。此多约简SVM有两个约简步骤，即用PCA和样本选择算法分别减少训练数据的维数和个数。理论分析和实验结果表明：该方法可以大大减少系统的存储量和计算量，提高训练和识别时间，并具有较好的鲁棒性。

| Abstract: | This paper proposed a new hierarchical speaker identification system based on Multi-Reduced Support Vector Machine (MRSVM) and Principal Component Analysis (PCA) classifier to reduce the recognition time of speaker identification. First get a coarse judge by a fast scan of all registered speaker using PCA classifier, and then get a final decision-making by the proposed MRSVM. And the MRSVM has two reduction steps: PCA and kernel-based fuzzy clustering are used to reduce the dimensions and amounts of trainin... |
