C#調用科大訊飛離線語音合成TTS

1、窗體頂端窗體底端C#調用科大訊飛離線語音合成TTSc#調用科大訊飛的離線語音合成，需要在科大訊飛開放平臺: 注冊、創(chuàng)建應用(獲取APPID)、開通離線語音服務、下載SDK。SDK中目錄如下:關于目錄結構，訊飛平臺的資料庫中有介紹。bin目錄下有msc.dll動態(tài)庫。c#調用科大訊飛的語音合成，需要引用該文件。該文件是C語言生成的dll，C#沒辦法直接引用。所有需要用C#重新封裝一個TTS.dll，然后再在C#項目中引用封裝的TTS.dll。步驟:1.在VS中新建一個類庫項目(TTS)，新建一個類文件(TTS.cs)2.TTS.cs中的內容如下:using System;using System
