This is not pertinent given that you have the option of choosing which languages you're familiar with before you queue for a dungeon. If you can't follow instructions given in a particular language, don't queue with that language enabled.

The problem is the combination of PC and PS not being able to communicate effectively (save for a few scenarios like the PS player having a keyboard or a computer with voice chat) and the inherent slow response given the nature of controllers - the latter of which is obviously not PS specific, but still a very apparent obstacle.
