Different mixing levels sometimes reveal small dialogue details–this happened in the mono mix of Empire a lot, where the words at the beginning of sentences were buried in the stereo mix, but completely audible in the mono mix. I’ve only seen one case like that in Jedi, and it’s not very exciting:

When Jerjerrod says “I tell you, this station will be operational as planned.”, the mono mix reveals what’s either a stutter or a partially-enunciated “that” so that it sounds more like “I tell you, th-this station will be operational as planned.”

Not enough to even bother changing subtitles for, sadly.
