Well, thanks for the heads up, but there's already a good version available on these forums. It's set up for the game. It comes in English and German versions, and .. the best part: It's FREE!

I have been using it for years. It can be edited for your own voice phrases as well. Good mod. Actually, make that ... Great mod!
Enjoy ..
