在.net中要实现语音合成可以利用微软的语音技术，利用微软的这一技术，需要安装Microsoft Speech SDK和语音库，安装之后，调用com中的Microsoft Speech Object Library，即可实现语音合成。

MicrosoftSpeech SDK 5.1的下载地址：

下面是调用语音合成的一个类

using System;using SpeechLib;namespace SpeechTest{    /// <summary>    /// TTS语音合成类    /// </summary>    public class TTSSpeech    {        //语音合成对象        SpVoice voice = null;        /// <summary>        /// 构造函数        /// </summary>        /// <param name="rate">发音频率（-10~10）</param>        /// <param name="volume">音量大小（0~100）</param>        /// <param name="voiceName">播音员名称</param>        public TTSSpeech(int rate,int volume,string voiceName)        {            voice = new SpVoice();            //设定音量大小            voice.Volume = volume;            //设定朗读频率            voice.Rate = rate;            //设定播音员            foreach (ISpeechObjectToken oneIOT in voice.GetVoices(string.Empty, string.Empty))            {                string[] pVoice = oneIOT.Id.Split(new char[] { '\\' });                int count = pVoice.Length;                string vName = pVoice[count - 1];                if (sVoice == voiceName)                {                    voice.Voice = (SpObjectToken)oneIOT;                }            }        }        /// <summary>        /// 根据文本生成音频文件        /// </summary>        /// <param name="txtSound">需要转化为声音的文本</param>        /// <param name="filePath">音频文件路径</param>        public void CreateSoundFile(string txtSound,string filePath)        {            //如果存在音频文件,则删除            if (File.Exists(filePath))            {                File.Delete(filePath);            }            SpeechStreamFileMode spFileMode = SpeechStreamFileMode.SSFMCreateForWrite;            SpFileStream spFileStream = new SpFileStream();            spFileStream.Open(filePath, spFileMode, false);            voice.AudioOutputStream = spFileStream;            SpeechVoiceSpeakFlags flag = SpeechVoiceSpeakFlags.SVSFlagsAsync;            int n = voice.Speak(txtSound, flag);            voice.WaitUntilDone(1000);            spFileStream.Close();        }        /// <summary>        /// 播放声音        /// </summary>        /// <param name="txtSound">需要转化为声音的文本</param>        public void PlaySound(string txtSound)        {            SpeechVoiceSpeakFlags flag = SpeechVoiceSpeakFlags.SVSFlagsAsync;            voice.Speak(txtSound, flag);        }    }}
