Where to find sounds and/or commands for repeating background NPC chatter?

[teresatiger]

Hi, I'm attempting to remove all of the random spitting, coughing, etc. (bodily functions, basically) from the game, most of which seem to be in the soundbanks. However, there are a few that don't seem to be (like the soldier who farts and then laughs like an idiot), which means that they are probably included as "dialogue." I've just learned how to unpack and re-encode the sounds contained in the soundbanks but dialogue is a whole other story. Is there a relatively simple way of locating individual tracks (repeating NPC background dialogue) and removing them, or editing the scripts to disable them altogether? Any suggestions for scripts to look at or how to access and edit those particular sound tracks would be much appreciated!
