//如果这个语音大于 2 个
if (listArr.size() >= 2){
   AudioInputStream audio1 = AudioSystem.getAudioInputStream(new File(dir+listArr.get(0)));
   AudioInputStream audio2 = AudioSystem.getAudioInputStream(new File(dir+listArr.get(1)));
   AudioInputStream audioBuild = new AudioInputStream(
         new SequenceInputStream(audio1, audio2),
         audio1.getFormat(),
         audio1.getFrameLength() +
               audio2.getFrameLength()
   );
   AudioInputStream audio3;
   //大于两个时继续合并
   for(int i = 2; i<listArr.size();i++){
      audio3 = AudioSystem.getAudioInputStream(new File(dir+listArr.get(i)));
      audioBuild = new AudioInputStream(
            new SequenceInputStream(audioBuild, audio3),
            audioBuild.getFormat(), audioBuild.getFrameLength() +
            audio3.getFrameLength()
      );
   }
   //生成语音
   AudioSystem.write(audioBuild, AudioFileFormat.Type.WAVE, fileOut );

} else {
   //TODO::否则只有一个,直接返回语音路径
 
}

注意 , 生成的语音要 比特率 一致,否则声音会很难听,如果要改为一直,则可以用百度音乐右上角工具来改变
