Sound Command that can intercept the Thread

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 theSpeechRecognized 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.
