C#调用科大讯飞离线语音合成TTS
c#调用科大讯飞的离线语音合成，需要在科大讯飞开放平
台:http://www.xfyun.cn 注册、创建应用(获取APPID)、开通离线语音服务、下载SDK。 SDK中目录如下:
关于目录结构，讯飞平台的资料库中有介绍。
bin目录下有msc.dll动态库。c#调用科大讯飞的语音合成，需要引用该文件。该文件是C语言生成的dll，C#没办法直接引用。所有需要用C#重新封装一个TTS.dll，然后再在C#项目中引用封装的TTS.dll。 步骤:
1.在VS中新建一个类库项目(TTS)，新建一个类文件(TTS.cs) 2.TTS.cs中的内容如下:

using System.Collections.Generic; using System.Linq; using System.Text;
using System.Runtime.InteropServices; namespace TTS {
