Creating dialogue for new races?

Hello all! I'm in the middle of creating the Ur-Quan (from Star Control 2) for Dark Avatar. I've gotten all the music, pictures, and animations packaged together, but now the only problem is that they don't have that distinct Ur-Quan personality. Instead of saying stuff like "Boy, you sure suck at war!" They should instead say things like "Submit or Die!" Is there any way I can create a unique set of dialogue for these guys? Any help would be greatly appreciated.
