新建两个基础类

现在新建执行类和方法，先在d盘放一个1.mp3的文件。以下代码就是把1.mp3转换成变声后的2.mp3
byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.73, 0.73); 后面的0.73就是变声参数。最后会给出各种变声参数

各种参数类
LUOLI(0.6, 0.6, "萝莉", 1, dispatcher -> {})
byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.73, 0.73);改为
byte[] pcmBytes = speechPitchShiftMp3("d://1.mp3", 0.6, 0.6);就可以了
