C# windows语音识别与朗读示例，供大家参考，具体内容如下
本示例通过windows语音识别功能进行语音识别和文本朗读。
打开windows麦克风，点击start按键，大声朗读 “中国”、“美国”、“英国”，识别成功将发出“嘟”的提示音并朗读对应结果。
用到的语音识别模块包括：
using System.Speech.Recognition;
using System.Speech.Synthesis;动态连接库文件在我的资源中下载.System.Speach.dll
示例界面如下：
程序源码如下：
using System;
using System.Runtime.InteropServices;
using System.Speech.Recognition;
using System.Speech.Synthesis;
using System.Threading;
using System.Windows.Forms;
namespace Test
{
public partial class FormVoiceControl : Form
{
static SpeechSynthesizer SS = new SpeechSynthesizer();
private SpeechRecognitionEngine SRE = new SpeechRecognitionEngine(); //语音识别模块
private bool SRE_listening = false;
private int wordid;
private string shibie;
[DllImport("kernel32.dll")]
public static extern bool Beep(int freq, int duration);
public FormVoiceControl()
{
InitializeComponent();
}
public void InitVoice() //语音识别初始化
{
//SS.SelectVoice("lily");
SRE.SetInputToDefaultAudioDevice(); // 默认的语音输入设备，也可以设定为去识别一个WAV文
GrammarBuilder GB = new GrammarBuilder();
GB.Append(new Choices(new string[] { "中国", "美国", "英国"}));
DictationGrammar DG = new DictationGrammar();
Grammar G = new Grammar(GB);
G.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(G_SpeechRecognized); //注册语音识别事件
SRE.EndSilenceTimeout = TimeSpan.FromSeconds(2);
SRE.LoadGrammar(G);
}
void G_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Beep(500, 500);//已识别提示音
string result = e.Result.Text;
switch (result)
{
case "中国":
shibie = "中国：五星红旗";
choice(0);
break;

t2.Start();
}
void ShowAnswer() //线程
{

this.BeginInvoke(mi);
}

case 0:
SS.Speak("五星红旗");
break;
case 1:

break;
case 2:

break;
}
}
private void FormVoiceControl_Load(object sender, EventArgs e)
{
InitVoice();
}
