Thanks Pfeil
I got it to work on a cockpit button when running FSX standalone , just to get the hang of it. Because I normally use oculus rift with FSX , I then set up the button x,y coordinates when viewed thru the rift. When I gave the correct voice command , I could see that the mouse arrow was not exactly over the button even if I was looking directly at it, and therefore the mouse click could not activate it. For the button to activate , I would have to have my head in the exact same position every time I said the command, which of course is impossible. I'm sure someone has figured out a fix . I will put a post in vrsimulations forum and flyinside forum to look for other voice attack users.
