近期项目中出现在离线情况下文字转语音的需求
进过尝试返现jacob还不错
一下为开发记录：
1.pom.xml中引入jacob.jar
<dependency><groupId>com.hynnet</groupId><artifactId>jacob</artifactId><version>1.18</version></dependency>
2.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）
百度网盘地址：jacob-1.18-M2
提取码：ktdn
3.java代码如下：
package com.whzc.test;import com.jacob.activeX.ActiveXComponent;import .Dispatch;import .Variant;/*** 文字转语音测试* jdk bin文件中需要导入jacob-1.17-M2-x64.dll* @author zk*@date: 6月25日 上午10:05:21*/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 0-100ax.setProperty("Volume", new Variant(100));// 语音朗读速度 -10 到 +10ax.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100Dispatch.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
