(1) 分别采集一段浊音和清音语音信号(是你自己说的),采样率为8KHZ,量化精度为16比特线性码;
(2) 分析帧长取为30ms(或10ms~50ms);
(3) 根据语音信号倒谱分析和LPC谱分析的编程流程图(图2.1、图2.2)编制浊音语音信号谱分析的matlab程序,上机调试给出相应波形,并根据图形,观察共振峰情况;
(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。
(5) 在LPC谱分析中,改变阶数p (p分别等于4、8、12、40)时,观察对谱包络的影响,并与信号谱(DFT谱)进行比较。

libsvm-mat-2.89-3
SVM的多分类问题MATLAB工具包。传统的SVM只支持二分类问题,MATLAB自带的工具包也存在同样的问题。可以在setpath中导入此包,便可轻松将SVM问题扩展到多分类的层面。(A matlab toolkit to solving multi-classification problems based on svm. Traditional svm and the matlab toolkit svmtrain can only support for bi-classification problems which could hardly satisfy users requirments. U can import this toolkit by click setpath and can easily do what you like.)
