Windows有文字转语音功能，C#提供了调用的类库Interop.SpeechLib.dll

使用方法很简单，在你的项目中添加Interop.SpeechLib.dll引用，在类中引用：

using SpeechLib;

这里提供一个CVoice类 帮助实现语音播报

 public class CVoice
 {
     private static Speach mysp = Speach.instance();
     private static SoundPlayer _voiceplayer = new SoundPlayer();
     private static Thread threadplay;
     private static string _sound;
     public static string SoundfileName
     {
         get { return _sound; }
     }

     private static string _soundtext;
     public static string SoundText
     {
         get { return CVoice._soundtext; }
     }

     public static void Playfile(string soundfile)
     {
         _sound = soundfile;
         threadplay = new Thread(mysoundplay);
         threadplay.Start();
     }

     public static void Play(string soundtext)
     {
         try
         {
             _soundtext = soundtext.Replace("重", "虫");  //解决都“zhong”的问题
             mysp.AnalyseSpeak(soundtext);
         }
         catch
         {
         }
     }

     public static void RePlay() //播放最后一次的语音
     {
         mysp.AnalyseSpeak(_soundtext);
     }

     public static void Pause() //播放最后一次的语音
     {
         mysp.Pause();
     }

     public static void Continue() //播放最后一次的语音
     {
         mysp.Continue();
     }

     public static void Stop()
     {
         //if (threadplay.ThreadState == ThreadState.Running)
         //{
         //    threadplay.Abort();
         //}
         mysp.Stop();
     }

     private static void mysoundplay()
     {
         try
         {
             _voiceplayer.SoundLocation = _sound;
             _voiceplayer.Play();
         }
         catch
         {
         }
     }

     public static Speach Speech
     {
         get
         {
             return mysp;
         }
     }
 }

 public class Speach
 {
     private static Speach _Instance = null;
     private SpeechLib.SpVoiceClass voice = null;

     private Speach()
     {
         BuildSpeach();
     }
     public static Speach instance()
     {
         if (_Instance == null)
             _Instance = new Speach();
         return _Instance;
     }

     public void SelectVoice(int index)
     {
         try
         {
             voice.Voice = voice.GetVoices("", "").Item(index);
         }
         catch
         {
         }
     }

     private void BuildSpeach()
     {
         if (voice == null) voice = new SpVoiceClass();
         SelectVoice(0);
     }
     public int Volume
     {
         get
         {
             return voice.Volume;
         }
         set
         {
             voice.SetVolume((ushort)(value));
         }
     }
     public int Rate
     {
         get
         {
             return voice.Rate;
         }
         set
         {
             voice.SetRate(value);
         }
     }
     private void Speak(string strSpeack)
     {
         try
         {
             int nn = voice.Speak(strSpeack.Replace("重", "虫"), SpeechLib.SpeechVoiceSpeakFlags.SVSFlagsAsync);
             Console.WriteLine(nn);
         }
         catch (Exception err)
         {
             throw (new Exception("发生一个错误：" + err.Message));
         }
     }

     public void AnalyseSpeak(string strSpeak)
     {
         Speak(strSpeak);
     }

     public void Stop()
     {
         voice.Speak(string.Empty, SpeechLib.SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak);
     }
     public void Pause()
     {
         voice.Pause();
     }
     public void Continue()
     {
         voice.Resume();
     }
 }

在需要的地方只需要CVoice.Play（“语音播报内容”）；
需要dll文件的私聊我！
