可以实现的声音种类：萝莉、大叔、肥仔、搞怪、熊孩子、慢吞吞、网红女、困兽、重机械、感冒、空灵等。
本方法是通过github开源的项目 TarsosDSP
废话不多说，先上代码
这里从maven上找了一个fork TarsosDSP打包的jar包，源码一样。也可以直接从TarsosDSP项目上把jar包下载到本地

<artifactId>jave-core</artifactId>

public static void main(String[] args) throws Exception {
//这里返回的是pcm格式的音频
byte[] pcmBytes = speechPitchShiftMp3("/home/li/Music/silk2pcm/file.mp3", 0.6, 0.6);
//如果需要转成wav则需要给pcmBytes增加一个头部信息
//TarsosDSP中也有输出Wav格式音频的处理器，这里没有使用。
byte[] wavHeader = pcm2wav(bytes);
OutputStream wavOutPut = new FileOutputStream(tempFile);
wavOutPut.write(wavHeader);
wavOutPut.write(bytes);
wavOutPut.flush();
wavOutPut.close();
// 对于各种声音类型，以及所需添加的处理器，还有处理器参数代码，将在本文最后给出。
//如果需要转mp3格式的，也可以给我留言，我会加上。
