Question

我有问题。我在c＃中创建了一个语音识别程序。我希望我的程序能够检测到错误的命令。

我尝试使用try和catch但我认为我弄错了。

void Default_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        string speech = e.Result.Text;

        switch (case)...     
        {
              //Commands
        }  

    }
try
{
    if (speech != e.result.Text)
    Bill.Speak("You have given an invalid command. Please try again.");
}
catch{}

我该如何正确地做到这一点？

Answer 1

只需在开关案例中添加默认值

  switch (speech)
  {
    case "1":
      Bill.Speak("Command 1");
      break;
    case "2":
      Bill.Speak("Command 2");
      break;
    default:
      Bill.Speak("You have given an invalid command. Please try again.");
      break;
   }

Answer 2

我认为您想要的是您的交换机的默认设置。所以

    switch (case)...     
    {
          //Commands
          default: // not recognized
            Bill.Speak("You have given an invalid command. Please try again.");
    }

Answer 3

添加默认： Bill.Speak（“我不理解命令”）;
