QuestionSound Command that can intercept the Active Thread Pin

Good Day all

i am working on a Kinect Sensor Program, but i think this question can best be answered by the WPF forum.

In my Kinect Project , the User can use Kinect Gestures or Voice Commands. THe Gestures work nicely its like one is using a mouse. i have a challenge with the Voice Commands which follow a certain Process. Please note that this functionality works well when one is not using voice commands.

Let me make a simple example.

i have a 3 Buttons

Button 1 = "System Ok "

Button 2 = " View Error"

Button 3 = "System Reboot"


Step 1: Now the logic say , if a user enter a wrong command , the System must play a sound for Error and the button for " View Error" must Animate.

Step 2: The Rule goes on and say if the User has not click the " View Error" within 5 seconds , Stop the Animation on the " View Error"

Step 3: and Animate the "System Reboot" and play the Sound for "System Reboot"

Now on a normal button click with a Mouse , this would work. But now i am not clicking the Button Physically, i am using Voice Commands and i have trapped the SpeechRecognized event which is defined like this
private void SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            // Speech utterance confidence below which we treat speech as if it hadn't been heard
            const double ConfidenceThreshold = 0.3;

            // Number of degrees in a right angle.
            const int DegreesInRightAngle = 90;

            // Number of pixels turtle should move forwards or backwards each time.
            const int DisplacementAmount = 60;

            this.ClearRecognitionHighlights();

            if (e.Result.Confidence >= ConfidenceThreshold)
            {
                switch (e.Result.Semantics.Value.ToString())
                { 

                    case "VIEWERROR":
                        Error_Escaped = true;
                        btnViewError_Click(null, null); 
                        break;
                    case "SYSTEMREBOOT":
                        btnSystemReboot_Click(null, null);
                        break;
                    case "SYSTEMSTATUS":
                        SystemStatus_Click(null, null); 
                        break; 
                }
            }
            else
            {
                // set the status text
                this.Status.Content = Properties.Resources.GrammarConfidenceLow;
                Logger.NormalLog("The Confidence is low , the Grammar is not Recognised as a Command", Generics.Generics.ActivePage) ;
            }
        }

as you can see i am clicking the Buttons programmatically. So if i don't click the "View Error" button within 5 seconds , the System Reboot will start playing another sound.

That was about the Process. Now my challenge is that. After i used a wrong option according to my Process, the "View Error" button will give a sound and i will give a Voice Command to Stop the Sound , the next in the Process will still be fired. So i debugged the code and i realised that the Program , runs all the code that was running and when its done, it hit the "SpeechRecognized" event later, i want to intercept and give the Voice Command the same ability as a button click done with a mouse can do.

This is a function that runs , when there is an Error
private void ViewError()
{

    Error_Escaped = false;
    ResetBlinking(this.btnViewError);
    AnimateButton(this.btnViewError);
     Generics.Generics.WaitNSeconds(5);
     if (Error_Escaped == false)
     {
         SystemReboot();
     }
}

This will set the Flag for "Error_Escape = false " Which means no one has clicked the button. and it will Animate the Button and wait for 5 second which is my custom interval calculator. Now while its waiting i would keep saying some Voice Command to Stop it. it will still continue while i wait , it will jump to System Reboot which will have its sound. i want the

SpeechRecognized(object sender, SpeechRecognizedEventArgs e)

event to fire when i need it not after the other event of buttons are fired.
