And you should check at torment.warparadise.com, because they just upladed the corrected version of the .tlk files. EDIT : Actually, it wasn't uploaded, yet. It should be soon as DarkXan as finished working on them.
I have tested voice.bif, and was able to hear the french version by replacing the english voice.bif with the french one. I didn't need to extract the wavs in the override folder. But, I tried it also, and was able to extract the wavs/acm using the english chitin.key. I got no problem, and it works.
So, it's up to you. I can send you the .bif, or the wavs in a zip file. You can also try voice.bif, and if it doesn't work, you'll extract the wavs/acm using winbiff or I'll send them to you.
There's this nice website we can use to send the file(s) : http://www.yousendit.com
Simpler than ftp or icq
