本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。(This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.)

k-means算法是模式识别十大算法之一 matlab仿真的k-means聚类算法(k-means algorithm for pattern recognition algorithm is one of the top ten k-means clustering algorithm)

数据归一化函数，有些matlab没有此函数，在此，上传一个函数让大家共享，谢谢(Data normalization function, some matlab does not have this function, in this, the upload function to share, thank you )

说明：  matlab的mapminmax函数（投影映射），在使用libsvm中没有它总是报错~~(The mapminmax matlab function (projection map), in the use of libsvm not it always error ~ ~)
