So I'm making a mod for someone and they asked me if I could replace the battle chatter of the republic to some voice lines from the clone wars TV show.

Is that possible?

If so, how do I do it?

I'm not very familiar with sounds regarding BF2 so I don't know how to add customs sounds at all.

I could learn from one of the other tutorials, but none of them mention how to replace NPC speech.

What should I do?
