1.下载jacob,将 jacob-1.18-x64.dll 或者 jacob-1.18-x86.dll 复制到 “JAVA_HOME”\bin 下(注意版本:根据JDK的安装版本选择)
2.百度网盘地址:jacob.jar
3.java代码如下:
package com.whzc.test;
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
/**
* 文字转语音测试
* jdk bin文件中需要导入jacob-1.17-M2-x64.dll

public class jacobtest {
public static void main(String[] args) { ActiveXComponent ax = null;
String str="请A001号到3号窗口";
// String str="华为 new bee";
try { ax = new ActiveXComponent("Sapi.SpVoice");
//运行时输出语音内容
Dispatch spVoice = ax.getObject();
// 音量 0-100
ax.setProperty("Volume", new Variant(100));
// 语音朗读速度 -10 到 +10
ax.setProperty("Rate", new Variant(-2));
// 执行朗读
Dispatch.call(spVoice, "Speak", new Variant(str));
//下面是构建文件流把生成语音文件
ax = new ActiveXComponent("Sapi.SpFileStream");
Dispatch spFileStream = ax.getObject();
ax = new ActiveXComponent("Sapi.SpAudioFormat");
Dispatch spAudioFormat = ax.getObject();
//设置音频流格式
Dispatch.put(spAudioFormat, "Type", new Variant(22));
//设置文件输出流格式
Dispatch.putRef(spFileStream, "Format", spAudioFormat);
//调用输出 文件流打开方法,创建一个.wav文件
Dispatch.call(spFileStream, "Open", new Variant("E:\\test.wav"), new Variant(3), new Variant(true));
//设置声音对象的音频输出流为输出文件对象
Dispatch.putRef(spVoice, "AudioOutputStream", spFileStream);
//设置音量 0到100
Dispatch.put(spVoice, "Volume", new Variant(100));
//设置朗读速度
Dispatch.put(spVoice, "Rate", new Variant(-2));
//开始朗读
Dispatch.call(spVoice, "Speak", new Variant(str));
//关闭输出文件
Dispatch.call(spFileStream, "Close");
Dispatch.putRef(spVoice, "AudioOutputStream", null);
spAudioFormat.safeRelease();
spFileStream.safeRelease();
spVoice.safeRelease();
ax.safeRelease();
} catch (Exception e) { e.printStackTrace();
}
}
}
4,运行即可,声音为系统默认语音
常见报错有:
1、找不到jacob.dll,配置路径问题(确认jacob.dll配置正确)
java.lang.UnsatisfiedLinkError: no jacob in java.library.path
2、找不到资源文件,资源文件路径问题(查看程序中资源文件路径的设置,并检查资源文件的存放路径)
com.jacob.com.ComFailException: Invoke of: Open
3、jacob.dll或jacob.jar对应版本错误
com.jacob.com.ComFailException: A COM exception has been encountered:
