k-means
K-means算法是最为经典的基于划分的聚类方法,是十大经典数据挖掘算法之一。K-means算法的基本思想是:以空间中k个点为中心进行聚类,对最靠近他们的对象归类。通过迭代的方法,逐次更新各聚类中心的值,直至得到最好的聚类结果。(K-means algorithm is based on the division of the classic clustering method, is ten classic one of data mining algorithm. K-means the basic idea of the algorithm is: to the space K point as the center of the cluster analysis, near their object classification. Through the iterative method, each successive update clustering center value, until get the best clustering results.

Matlab函数 采集一段浊音和清音语音信号
(1) 使用录音软件或者Matlab函数,分别采集一段浊音和清音语音信号(是你自己说的,如:a,o,s等),采样率为8KHz,量化精度为16比特线性码,存在自己指定的目录下,例如D盘根目录下叫sound的文件夹中,录音文件名为yourfilename_a.wav,yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。
(2) 根据语音信号的短时平稳特性,分析帧长取30ms(或10ms~50ms);
(3) 利用上述基音提取的三种方法(任选两种方法)的编程流程图(图1、图2和图3)编制浊音语音基音提取的matlab程序,上机调试给出相应波形,并根据图形,分析计算出基音周期。所用公式为:
(1.5)
其中 是基音脉冲处所对应的位置, 是抽样频率, 是基音周期。
(4) 将语音信号换为清音语音,运行程序,与浊音语音的运行结果进行比较,并得出结论。
