所以我使用Kinect编写了以下代码作为我的PC的基本语音控制代码，它一直运行良好！但是当我尝试添加一种“静音”代码时，它就停止了工作。我弄清楚为什么它停止工作，但我无法弄清楚如何让它与某种静音代码一起使用它会导致鼻子出血！我觉得答案很简单，我只是忘了怎么做，或者我还没有想到它......那就是杀了我的。
无论如何，正如您所看到的那样，问题是代码中稍后初始化的变量“listen”需要一个起始值才能在if和switch语句中使用它。我的起始值为0，因此在listen设置为1之前不会运行任何内容，只有在我说“Hey Jarvis”（当然是由钢铁侠启发）时才会发生。但是，当代码通过一个新的循环时，它会将变量“listen”重置为零，因为它是初始化的值！我无法想出一种方法，使变量值对我的命令灵活，而与代码的循环次数无关。真是太棒了！如果你们中的任何人能够阐明这一点，我将是一个非常幸福的人。如果有帮助，请随意取笑你看到的任何菜鸟代码......请告诉我我的诺布眼睛看不到的东西！

答案 0 :(得分：0)
为什么不将switch声明包含在另一个switch内。
例如：
switch (listen)
{
case 0:
switch (e.Result.Text)
{
case "Hey Jarvis":
Console.Write(" Yes Gary?");
listen=1;
break;
case default:
Console.Write(" Muted");
break;
}
break;
case 1:
// All your normal code
}
Haven之前没有使用过kinect-sdk，但我认为逻辑应该仍然存在。我认为你所写的内容非常棒，我一定会考虑将其用于某些事情。
您也可以从SreSpeechRecognized方法返回listen的值，而不是使用您可以将其作为参数的方法初始化它。
