语音播报（播报本地音频文件）实现收款金额的播报
最近项目需要实现语音播报收款金额，本来要使用百度AL开发平台的语音合成进行语音播报，虽然这个是可以完美实现，但是这个在免费的情况下有这播放条数的限制，所以最终决定使用播放本地语音的方式进行实现。不多说，直接贴代码，代码也都进行了注释：
一、FileUtils文件读取工具类
public class FileUtils {
public static AssetFileDescriptor getAssetFileDescription(String filename) throws IOException {
AssetManager manager = CardDoctorApplication.getContext().getAssets();
return manager.openFd(filename);
}
}CardDoctorApplication是自己的application类，就不贴出来了。

} 四、新建assets文件夹，把音频文件放在assets目录下
此demo可支持到千亿播放，对播放的语序也进行了一些处理，但是可能还有些许情况没有考虑到，需要使用的朋友可以按自己的需求自行添加
新添加内容：
最近接到反馈，说语音播报的速度太慢，跟一个老大爷一样，所以在处方面做了优化。此处没有使用Android自带的播放器，而是使用Google支持的第三方的播放器ExoPlayer ，需要了解ExoPlayer 可到这个网址了解，https://google.github.io/ExoPlayer/
ExoPlayer gitgub地址https://github.com/google/ExoPlayer
下面直接贴出代码，新的代码只是一个方法，替换之前的播报方法即可，或者根据需求使用两者中的其中一个即可。
