Java使用Jacob调用SAPI合成语音



Java使用Jacob调用SAPI合成语音：
1.配置Jacob:我这里使用的jacob为jacob-1.18-M2，jacob-1.18-M2下载下来之后，解压缩文件，
里面的文件为docs、jacob.jar、jacob-1.18-M2-x64.dll、jacob-1.18-M2-x86.dll、LICENSE.TXT、README.txt；
把jacob.jar复制到项目的lib目录下面，jacob-1.18-M2-x64.dll和jacob-1.18-M2-x86.dll是两个动态库文件，
它们指JDK的安装版本，如果JDK是64位的，那么需要把jacob-1.18-M2-x64.dll复制到JRE BIN目录下面，因为
我装的JDK是32位的，所以我把jacob-1.18-M2-x86.dll复制到JRE BIN目录下面，
我的JRE路径为G:\Program Files (x86)\Java\jre7\bin。
2.代码如下

3.把wav语音文件转换为pcm，其中用的Jar包为sound.jar，代码如下：

package com.jacob;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;/** * 与声音有关的工具类 * @author suyunlong * */public class SoundUtil{/** * 将WAV格式的音频文件转换为PCM格式的文件 * @param wavFilePath WAV文件路径 * @throws UnsupportedAudioFileException * @throws IOException */public static void wavToPcm(String wavFilePath){try{File wavFile=new File(wavFilePath);AudioInputStream sourceAudioInputStream=AudioSystem.getAudioInputStream(wavFile);// 此处的转换必需是16bit的音频文件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();}}/** * 获取音频文件的编码格式  * @param wavFilePath 音频文件格式 * @return String */public static String getWavFormat(String wavFilePath){File wavFile=new File(wavFilePath);AudioInputStream ais;String result="";try{ais=AudioSystem.getAudioInputStream(wavFile);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");}}
