| 摘 要： | 为了改善在矢量量化说话人识别中，采用模板(码书)表征说话人，模板的质量对识别系统的性能。采用遗传算法改进模板的生成方式，构建了一种GA／VQ说话人辨认系统，给出了一种GA／VQ识别算法，通过遗传操作获得全局优化的说话人模板。实验证明，GA／VQ方法提高了码书的质量，比经典矢量量化识别系统识别率高。

| Abstract: | In speech signal processing, the vector qua ntization(VQ) is an important method. The speaker recognition method based on VQ is researched in this paper. In VQ speaker recognition, codebook was adopted t o represent the speaker, and the performance of system is mainly influenced by the qua lity of codebook. Genetic algorithm was adopted in this paper to get global opti m ized speaker codebook and a GA/VQ speaker identification algorithm was proposed. E xperiment results show that this method improves the quality of codebook, the sy s tem based on GA/VQ performs higher correct identification rates compared with th at based on conventional VQ method. |
