Found this on the internet 4-5 years ago, and it seems folks are still looking for it.
Can't remember where I downloaded this, or who made it either ( sorry ).
Basic DOS executable, throw it and either citalog.res(logs) or citbark.res(ingame utterances and such) into a directory, and run the executable. it'll direct you from there. Produces standard .WAV files.
Works for english, not sure about the french or  german voice files though.

... ( Reads the absolute last line at the bottom of the linked page ) ...
... Nice going.
:-P

Just kidding! Thanks for the info though, I actually had forgotten where it was from.
