讓程式說話
1. ASUS X450J / Windows 10 /VS 2012
2. 文字轉語音，語音轉mp3

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//---
using System.Speech.Synthesis;
// 5. 加入 mp3 套件
// Install-Package NAudio.Lame
// 6. 使用命名空間
using NAudio.Wave;
using NAudio.Lame;
// 8.
using System.IO;

// 語音合成
// 1. 加入語音程式庫 System.Speech
// 2. 使用命名空間 using System.Speech.Synthesis;
// 3. 用語音合成類別(SpeechSynthesizer)建立 語音物件
SpeechSynthesizer 語音物件 = new SpeechSynthesizer();
// 4. 呼叫說(Speak)方法，輸出字串
語音物件.Speak("君不見黃河之水天上來，奔流到海不復回，君不見高堂明鏡悲白髮，朝如青絲暮成雪。");
// 7. 轉mp3
// Ref: http://stackoverflow.com/…/c-sharp-save-text-to-speech-to-m…

//do speaking
reader.Speak("君不見黃河之水天上來，奔流到海不復回，君不見高堂明鏡悲白髮，朝如青絲暮成雪。");
//now convert to mp3 using LameEncoder or shell out to audiograbber

}
}
