LVQ算法( Learning Vector Quantization,学习矢量量化网络)是一种基于模型(神经网络)的方法,本实验要实现的是对LVQ改进的聚类方法——MLVQ(闫德勤等人提出)。该方法克服了LVQ算法对初值敏感的问题和广义学习矢量量化(GLVQ)网络算法性能不稳定的缺点。(附文章)-LVQ algorithm (Learning Vector Quantization. learning vector quantization network) is a model-based

说话人识别是语音识别的一种特殊方式,其目的不是识别语音内容,而是识别说话人是谁,即从语音信号中提取个人特征。采用矢量量化(VQ)可避免困难的语音分段问题和时间归整问题,且作为一种数据压缩手段可大大减少系统所需的数据存储量。本文提出了识别特征选取采用复倒谱特征参数和对应用VQ的说话人识别系统改进的一种方法。当用于训练的数据量较小时,复倒谱特征可以得到比较稳定的识别性能。VQ的改进方法避免了说话人识别系统的训练时间与使用时间相差过长从而导致系统的性能明显下降以及若利用自相关函数带来的大量运算。-Sp
