使用opensmile提取音频的特征，得到特征向量，并扔进libsvm中进行分类训练测试
我们做的是从语音中识别出情感，我们先从网上下载许多视频，电影、电视剧、综艺访谈节目等等，截取其中带有表情的视频片断，再从每个视频中提取出语音单独进行识别情感。怎么从视频中提取出语音，具体见我上一篇博客从视频提取出音频
一、首先使用opensmile对音频进行处理，注意处理的音频格式必须为wav格式（其他格式并不识别），看书时候看到了下，wav格式的音频基本是属于无损音质吧，微软出的。
1、首先在网上下载opensmile，我使用的是openSMILE-2.1.0这个版本，可以去网上下载，点击打开链接
opensmile是一个在windows命令行下操作的指令，操作如下：
先切换到处理文件的目录下，cd D:\openSMILE-2.1.0\bin\Win32
再使用此命令进行处理SMILExtract_Release -C D:\openSMILE-2.1.0\config\IS09_emotion.conf -I "要处理的音频目录"如（d:/a.wav） -O "要保存特征向量的路径如（d:/a.txt）"，我的命令行操作如下：SMILExtract_Release -C D:\openSMILE-2.1.0\config\IS09_emotion.conf -I d:\6.wav -O d:\6.txt
最后得到的txt格式如下

前面的都不用管，都是一些属性值，只要提取出最后一行的数据保存下来就好了。
二、使用libsvm进行特征训练并测试
首先要将得到的向量化成libsvm能处理的格式，我使用的libsvm是libsvm-3.17，附上下载路径点击打开链接
格式如下：

格式如下：libsvm的处理很简单，代码如下：
package pkg;
import java.io.IOException;
import src.*;
public class SVM {
public static void main(String[] args) throws IOException {
//进行特征缩放
// String[] train={"-l","0", "-u","1","-s","training_result","training"};
// svm_scale.main(train);
// String[] test={"test_result","test"};
// svm_scale.main(test);
String[] trainArgs = {"training33"};//directory of training file
String modelFile = svm_train.main(trainArgs);
System.out.println("......."+modelFile);
String[] testArgs = {"test33", modelFile, "result"};//directory of test file, model file, result file
Double accuracy = svm_predict.main(testArgs);
System.out.println("SVM Classification is done! The accuracy is " + accuracy);
}
}
其中training33是一个存放测试集的文件，modeFile是训练之后得到的模型，test33是测试集，result是存放测试结果的
最后测试结果如下：
optimization finished, #iter = 435
nu = 0.6190058618762699
obj = -264.8696954342523, rho = -0.3560931956419671
nSV = 376, nBSV = 279
*
optimization finished, #iter = 382
nu = 0.7197531820350304
obj = -292.1362097337123, rho = 0.48854453043532936
nSV = 397, nBSV = 318
Total nSV = 1718
.......training33.model
Accuracy = 37.362637362637365% (68/182) (classification)
SVM Classification is done! The accuracy is 0.37362637362637363准确率为37%，好低啊。
被老师一顿狠批，接下来就是要提高正确率了，调整惩罚系数C和核函数G，得到最优的结果。
