I know it is possible to get the sound files from the pre-mission briefings from both the regular and Secret Order missions. I also know where to get the after-mission briefings as well - the same location.
Is there a way to get the voice files that appear in the cutscenes and/or the voice files that are in the actual missions themselves? I haven't been able to locate either.
As of 23JUN13: I released a new small texture mod! Check it out here
