java jacob语音合成_Java使用Jacob调用SAPI合成语音
基于語音測試需要，需要將文字數據轉換成語音數據，文章未經原作者允許轉載，只用于記錄。
1.Jar包
版本號：1.18
maven地址：https://mvnrepository.com/artifact/com.hynnet/jacob
2.環境設置
JDK版本：1.8(原來采用1.7設置與1.8一致，一直報錯，還不知道是不是版本的原因，原作者使用1.7沒問題)
具體設置：解壓后，將x86或x64的dll文件放入c:\windows\system32或syswow64目錄下；同時也放入jdk和jre的bin、lib目錄里；

把wav語音文件轉換為pcm，其中用的Jar包為sound.jar，該jar包自帶于jdk里，不用到處找了。

import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioFileFormat;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.UnsupportedAudioFileException;

*/
public class SoundUtil
{
/**
* 將WAV格式的音頻文件轉換為PCM格式的文件
* @param wavFilePath WAV文件路徑
* @throws UnsupportedAudioFileException
* @throws IOException
*/
public static void wavToPcm(String wavFilePath)
{
try
{
File wavFile=new File(wavFilePath);
AudioInputStream sourceAudioInputStream=AudioSystem.getAudioInputStream(wavFile);
// 此處的轉換必需是16bit的音頻文件
AudioInputStream targetAudioInputStream=AudioSystem.getAudioInputStream(AudioFormat.Encoding.ULAW,
sourceAudioInputStream);
String newFilePath=wavFilePath.substring(0,wavFilePath.lastIndexOf(".")+1)+"pcm";
AudioSystem.write(targetAudioInputStream,AudioFileFormat.Type.WAVE,new File(newFilePath));
}
catch(UnsupportedAudioFileException e)
{
System.out.println(e.getMessage());
e.printStackTrace();
}
catch(IOException e)
{
System.out.println(e.getMessage());
e.printStackTrace();
}
}
/**

* @param wavFilePath 音頻文件格式
* @return String
*/
public static String getWavFormat(String wavFilePath)
{
File wavFile=new File(wavFilePath);
AudioInputStream ais;
String result="";
try
{

AudioFormat af=ais.getFormat();
result=af.toString();
}
catch(UnsupportedAudioFileException e)
{
System.out.println(e.getMessage());
e.printStackTrace();
}
catch(IOException e)
{
System.out.println(e.getMessage());
e.printStackTrace();
}
return result;
}
public static void main(String[] args)
{
System.out.println(SoundUtil.getWavFormat("E://syl//C//test.wav"));
SoundUtil.wavToPcm("E://syl//C//test.wav");
}
}
5.測試報錯問題
問題：java.lang.UnsatisfiedLinkError: no jacob in java.library.path
解決：x86或x64的dll文件放入c:\windows\system32或syswow64目錄下；同時也放入jdk和jre的bin、lib目錄里；
問題：Could not initialize class com.jacob.com.ComThread
解決：更換JDK版本，我在本機上測試1.7會報錯，1.8通過，請自行嘗試；
