中文说明：%基于VQ的说话人识别系统，矢量量化起着双重作用。在训练阶段，把每一个说话者所提取的特征参数进行分类，产生不同码字所组成的码本。在识别(匹配)阶段，我们用VQ方法计算平均失真测度(本系统在计算距离d时，采用欧氏距离测度)，从而判断说话人是谁。本段代码是对音频进行训练，也就是提取特征参数
English Description：
%In VQ based speaker recognition system, vector quantization plays a dual role. In the training phase, the feature parameters extracted by each speaker are classified to generate codebooks composed of different codewords. In the recognition (matching) stage, we use VQ method to calculate the average distortion measure (the system uses Euclidean distance measure when calculating the distance d), so as to judge who the speaker is. This code is to train the audio, that is to extract feature parameters
