| 摘 要： | 该文针对LBG算法可能有空胞腔产生及有些码字利用率低的问题,提出了一种改进的矢量量化算法,并将其应用到与文本无关的说话人识别研究,得到了一种新的说话人识别方法.实验表明,这种方法对说话人的识别性能好于基于LBG算法的说话人识别方法.

| Abstract: | The traditional LBG algorithm is an important VQ method, but it has two disadvantages. First, empty cells may be produced, and secondly, some code vectors may be used only by very few training vectors in the LBG algorithm. In this paper, a modified LBG algorithm is proposed, and the design of a text-independent speaker recognition system based on the modified VQ algorithm is presented. Experiments show that the system has better performance than that based on the traditional LBG algorithm. |
