Hey, just DL'ed VAC ysterday for use in Battlefield 2. It has a lot of weapons and in-game functions that will be nice to tie to voice-activation. . .I'm going to test it thoroughly for a couple days, but I'm guessing you'll have my $9.99 before long.
One thing I've noticed already: I like the Push-to-Talk key, as I use Teamspeak while I game. However, in BF2, there is already a VoIP function in-game that lets you speak with up to five other squad members.
Some folks have taken to using the in-game chat for squad orders and in-game tactics, and their Teamspeak for joking/chatting with their clan members (especially in situations where clan members sometimes end up on opposing sides, and you don't want to discuss tactics in public chat)
So in this game, I (and others) use TWO push-to-talk keys. Any way you could integrate a LIST of keys that would make VAC ignore voice?
LOVE your program, and will be showing it off to my clan-members.
