Yes, just put the correct path to the vox in your config. There are 3 different vox sets, so you have to add the right directory in the speak config lines. There's a post from mervaka on how exactly it should look somewhere.. If you just look in the game directory where the vox is, you should be able to figure it out. Otherwise search by posts he's made. =D
*edit bah did it myself :P*
