I made a couple of replies to some comments, but i thought i would do a little post of details about something like this. I worked on a similar system for star citizen, using the inbuilt windows voice recog system. At it's core, systems like this are primarily voice activated macro's. They are a lot more useful for twitch/combat based games (specifically flight simulators). I would listen to microphone input, do a comparison for a specific string and emulate a keyboard press(or a combination of them for x amount of time) based on what was said. (Mouse too some times - although i spoke to tech support for star citizen, and had to be careful of how complex some commands could be, to ensure i did not break the eula). Side note: I have stopped production of mine until star citizen gets a little further along (and i am also working on a natural speaking system, to detect what you mean for the system to do, instead of specific strings - eg if i said show shields, show me the shields, lets see the shields it would differentiate between that and say putting the shield power forward).
