背景

使用Java实现：输入文本或指定播放文件路径，实现循环播放、停止、放入多个播放队列依次播放；这里我使用的是Springboot。

实现步骤：

1、Java要实现语音播报，需要引入文件jacob-1.18-x64.dll到jdk的安装目录>>bin目录，文件下载地址(下载后记得解压)：

2、创建一个Springboot项目，在pox.xml中引入jar包

<!-- /artifact/com.jacob/jacob 文字转语音 --><dependency><groupId>com.hynnet</groupId><artifactId>jacob</artifactId><version>1.18</version></dependency><!-- 播放MP3音乐 --><dependency><groupId>com.googlecode.soundlibs</groupId><artifactId>mp3spi</artifactId><version>1.9.5.4</version></dependency><!-- 如果需要解码播放flac文件则引入这个jar包 --><dependency><groupId>org.jflac</groupId><artifactId>jflac-codec</artifactId><version>1.5.2</version></dependency><!--播放音乐 使用第三方解决方案 (jaudiotagger.jar)--><dependency><groupId>org</groupId><artifactId>jaudiotagger</artifactId><version>2.0.3</version></dependency>

3、创建Music类，代码如下

package com.example.music;import com.jacob.activeX.ActiveXComponent;import .Dispatch;import .Variant;import org.jaudiotagger.audio.AudioFile;import org.jaudiotagger.audio.AudioFileIO;import org.ponent;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import sun.audio.AudioPlayer;import sun.audio.AudioStream;import java.io.File;import java.io.FileInputStream;import java.util.ArrayList;import java.util.List;@Component@RequestMapping("/music")public class Music extends Thread{//tts语音播报private static List<String> strList=new ArrayList<>();private static Thread tts = new Thread();//播放音乐private static AudioStream as=null;private static Thread t = new Thread();/*文字转语音播报开始*/@GetMapping("/ttsStart")public void ttsStart(String text) {ActiveXComponent activeXComponent = new ActiveXComponent("Sapi.SpVoice");//运行时输出语音内容Dispatch dispatch = activeXComponent.getObject();//文件名称long t1=System.currentTimeMillis();String strName= String.valueOf(t1);strList.add(strName);try{//生成语音文件activeXComponent = new ActiveXComponent("Sapi.SpFileStream");Dispatch fileStreamDispatch = activeXComponent.getObject();//音频activeXComponent = new ActiveXComponent("Sapi.SpAudioFormat");Dispatch audioDispatch = activeXComponent.getObject();//设置文件流格式Dispatch.putRef(fileStreamDispatch, "Format", audioDispatch);//设置音频流格式Dispatch.put(audioDispatch, "Type", new Variant(22));//调用输出文件流打开方法，创建一个.wav .mp3 .mp4 .wma文件Dispatch.call(fileStreamDispatch, "Open", new Variant("D:\\"+strName+".wav"),new Variant(3),new Variant(true));//设置声音对象的音频流输出流为输出文件对象Dispatch.putRef(dispatch, "AudioOutputStream", fileStreamDispatch);//设置音量0-100Dispatch.put(dispatch, "Volume", new Variant(100));//设置朗读速度Dispatch.put(dispatch, "Rate", new Variant(-2));//开始朗读Dispatch.call(dispatch, "Speak",new Variant(text));//关闭输出文件流Dispatch.call(fileStreamDispatch, "Close");Dispatch.putRef(dispatch, "AudioOutputStream", null);audioDispatch.safeRelease();fileStreamDispatch.safeRelease();dispatch.safeRelease();activeXComponent.safeRelease();//判断线程状态if(!tts.isAlive()){tts = new Thread(){public void run(){//是否正在播放音乐if(t.isAlive()){musicStop();}//播放音频ttsPlayer();}};tts.start();}}catch (Exception e) {e.printStackTrace();}}//播放音频public void ttsPlayer(){try {for(int i=0;i<strList.size();i++){//输出音频时长File file=new File("D:\\"+strList.get(i).toString()+".wav");AudioFile mp3= AudioFileIO.read(file);FileInputStream fileau=new FileInputStream("D:\\"+strList.get(i)+".wav");as=new AudioStream(fileau);//开始播放AudioPlayer.player.start(as);Thread.sleep(mp3.getAudioHeader().getTrackLength()*1000+500);}if(strList.size()>0){ttsPlayer();}}catch (Exception e){e.printStackTrace();}}/*文字转语音播报停止*/@GetMapping("/ttsStop")public void ttsStop(Integer index){try {//全部终止播放if(index==-1){//停止线程tts.interrupt();//停止播报AudioPlayer.player.stop(as);//清空列表所有元素strList.clear();}else if(index>-1){//将指定脚标删除strList.remove(strList.get(index));}}catch (Exception e) {e.printStackTrace();}}/*开始播放音乐*/@GetMapping("/playStart")public void musicStart(String path){//判断是否正在语音播报if(!tts.isAlive()){//停止线程t.interrupt();//停止播放AudioPlayer.player.stop(as);t = new Thread(){public void run(){try{//输出音频时长File file=new File(path);AudioFile mp3= AudioFileIO.read(file);//System.out.println(mp3.getAudioHeader().getTrackLength());//循环播放while (true){FileInputStream fileau=new FileInputStream(path);as=new AudioStream(fileau);//开始播放AudioPlayer.player.start(as);Thread.sleep(mp3.getAudioHeader().getTrackLength()*1000+500);}}catch (Exception e){e.printStackTrace();}}};//启动线程t.start();}}/*停止播放音乐*/@GetMapping("/playStop")public void musicStop(){try {//判断是否正在语音播报if(!tts.isAlive()) {//停止线程t.interrupt();//停止播放AudioPlayer.player.stop(as);}}catch (Exception e) {e.printStackTrace();}}}

4、启动项目后就可以使用了，接口信息如下

5、我本地是用的Postman测试如下：

我使用的线程控制的开始和停止，如有更好的方法欢迎留言讨论！
