Well, I'd hate to have to repeat myself to a voice esystem in combat where split seconds matter. It would be the like the real life equivalent of LAG.
Except the equivalent of flipping the table would be ripping out your "Siri" system before you eject. . .
"I'm sure you said Tornado Fist. I's that what you meant?"
*Explosion in background*
"SIRI YOU SON OF A-"
This also makes me wonder what happens when an enemy sabotages it. It might end up singing "Daisy, Daisy" while your trying to survive.
Not trying to be a douche but this brings up a lot of interesting combat scenarios that make me laugh
It could be useful for things such as scanning and communication though.
