c# 百度语音合成

前段时间做了语音转文字的功能，索性就把文字转语音一起做了，参考了下这位朋友的帖子。这里把得到的语音文件直接保存了，mp3格式，需要wav需要转换，百度返回的直接是压缩后的mp3。原文在这：http://blog.csdn.net/u012395622/article/details/46909653#comments，参考

开始代码：

首先是stringtoaudio类

这里使用的是我的百度语音识别appkey，可以自己去申请，很简单，请参考之前关于语音转文字的帖子或者上面的传送门

}
 
  
 
  
外部调用：
 
  
StringToAudio sta = new StringToAudio();
string audioFileName=sta.stringToAudio("测试文本",Application.StartupPath+"\\"+DateTime.Now.ToString("yyyyMMddhhmmssffff")+".mp3");
System.Diagnostics.Process.Start(audioFileName);
