Question

当我说＆＃34; space＆＃34;它应该继续插入空间，直到我说＆＃34;停止＆＃34;。所以这是我的代码：

    private void button1_Click(object sender, EventArgs e)
    {

        button2.Enabled = true;
      button1.Enabled = false;
        Choices sList = new Choices();
        sList.Add(new string[] { "space", "stop" });
        Grammar gr = new Grammar(new GrammarBuilder(sList));

        try
        {
            sRecognize.RequestRecognizerUpdate();
            sRecognize.LoadGrammar(gr);
            sRecognize.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sRecognize_SpeechRecognized);
            sRecognize.SetInputToDefaultAudioDevice();
            sRecognize.RecognizeAsync(RecognizeMode.Multiple);

        }
        catch { return; }

     }


    void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {

       textBox1.Text = e.Result.Text.ToString(); 
        //throw new NotImplementedException();
        if (textBox1.Text == "space")
            //while (!e.Result.Text.ToString().Equals("stop"))
            {
                SendKeys.Send(" ");

            }
    }

由于我只是初学者，所以如果可能的话请帮助我理解您的代码和评论。

创建一个调用Sendkeys.Send(" ")的计时器事件，然后在识别'空格'时启动计时器，并在识别'停止'时停止计时器。

using System.Threading;
Timer thetimer;
void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    if (e.Result.Text.ToString() == "space")
    {
        theTimer = new Timer(TimerCallback(timeExpired), 500); // 500 ms
    }
    else // if is stop
    {
        theTimer.Change(Timeout.Infinite, Timeout.Infinite); // stop the timer
    }
}

void timeExpired(Object stateInfo)
{
    SendKeys.Send(" ");
}

您也可以使用其他计时器机制，但这非常简单。
