Years ago there was a product called Game Commander....I used it...worked great. You would train it to your voice, saying the command, like "gear" then map the appropriate key stroke(s)...worked good off line. I used it mostly for comms to base, wingman, flight, etc. For instance I'd say "home" and assign the Tab X X comm(not sure what they are) same as hitting the multiple keys...nice, or rejoin, attack, cover me, permisson to land, takeoff,etc....Now I have them programmed to my HOTAS. So when the wife comes into the room an makes a comment, I don't bail out...LOL
