I'm downloading the macro addon for it now, it lets you make your own speech commands. For example I can make a command that goes like this:
Tell me about Julius Ceaser
And then the computer automatically opens the internet, goes to wikipedia, and pulls up the Ceaser article for me to read.
I have not tried any games with it yet, so I am not sure it works with them, but I will give it a try on Spore and post my results later.

:edit:
Oh and of course I gotta make the command from Supertroopers where he is saying "Enhance, enhance, enhance" to zoom into a picture lol.
