The NPC voices are stored in the .bifs and indexed in the .key. Simplest way to get at them would be the NearInfinity program, although you will need a javaVM isntalled for that to work, which modern windows lacks, so get one from Sun. IF you get NI working, it should be able to use acm2wav and export to standard format directly. I havent set this up in a while, but I think all you have to do is make sure the .exe is in the right folder.

Or, theres the winBIFF program from teambg which will also let you extract files from the .bifs, but it dosent integrate with acm2wav.
