我正在尝试制作语音识别器应用程序。使用C#。我创建了基本的应用程序,它工作正常。如何设置语音识别器启动和停止
现在我的问题是。
我该如何使用按钮控件来启动和停止语音识别器。
我使用SpeechRecognitionEngine
类
这里是我的代码。
private bool Status = false;
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
Choices dic = new Choices(new String[] {
"word1",
"word2",
});
public Form1()
{
InitializeComponent();
Grammar gmr = new Grammar(new GrammarBuilder(dic));
gmr.Name = "myGMR";
// My Dic
sre.LoadGrammar(gmr);
sre.SpeechRecognized +=
new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);
sre.SetInputToDefaultAudioDevice();
sre.RecognizeAsync(RecognizeMode.Multiple);
}
private void button1_Click(object sender, EventArgs e)
{
if (Status)
{
button1.Text = "START";
Status = false;
stslable.Text = "Stopped";
}
else {
button1.Text = "STOP";
Status = true;
stslable.Text = "Started";
}
}
public void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs ev)
{
String theText = ev.Result.Text;
MessageBox.Show(theText);
}
