.net4.0

using System.Speech;
using System.Speech.Synthesis;
using System.Windows.Forms;

1、输出语音

Type type = Type.GetTypeFromProgID("SAPI.SpVoice");
dynamic spVoice = Activator.CreateInstance(type);
spVoice.Speak("孙悟空，白骨精，唐僧！哈哈哈哈");

2、输出WAV 文件

SaveFileDialog file = new SaveFileDialog();
file.Title = "保存音频文件";
file.InitialDirectory = ".\\";//对话框的初始目录
file.Filter = "音频文件|*.wav";// 要在对话框中显示的文件筛选器
file.RestoreDirectory = true;//控制对话框在关闭之前是否恢复当前目录
file.FilterIndex = 1;//在对话框中选择的文件筛选器的索引，如果选第一项就设为1
file.AddExtension = true;
if (file.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{

int cnVoice, enVoice;
Type type = Type.GetTypeFromProgID("SAPI.SpVoice");
dynamic spVoice = Activator.CreateInstance(type);
dynamic colVoice = spVoice.GetVoices();//‘获得语音引擎集合
spVoice.Volume = 100;// ‘设置音量，0到100，数字越大音量越大
spVoice.Rate = 0;//
string langCN = "MSSimplifiedChineseVoice";// ‘简体中文
string langEN = "MSSam";// ‘如果安装了TTS Engines 5.1，还可以选择MSMike,MSMary
for (int i = 0; i < colVoice.Count; i++)
{
if (colVoice[i].Id == langCN)
cnVoice = i;
if (colVoice[i].Id == langEN)
enVoice = i;
}
int SSFMCreateForWrite = 3;
int SAFT22kHz16BitMono = 22;
int SVSFlagsAsync = 1;
string strText = "测试TTS";
Type type2 = Type.GetTypeFromProgID("SAPI.SpFileStream");
dynamic objFileStream = Activator.CreateInstance(type2);
objFileStream.Format.Type = SAFT22kHz16BitMono;
objFileStream.Open(file.FileName, SSFMCreateForWrite, false);
spVoice.AudioOutputStream = objFileStream;
spVoice.Speak(strText, SVSFlagsAsync);
spVoice.WaitUntilDone(-1);
objFileStream.Close();
