The Darkness (Ripped dialog)

I’ve been trying to rip the audio from the game, and keep running into roadblocks. I like the music from the game, but what I really want is the voice of the Darkness itself. I’ve tried many times with many tools, but none of the tools I’ve found seem to be able to extract any oggs or anything else from the xwc files. I have an iso that I transferred to USB from the digital download of the game, but after I extract the ISO, then I can’t get any further. I did try to make an ISO on my PC from the game cd, but no luck.
