It wouldn't surprise me if the different voices end up being the tells for mechanics on Savage because it's unusual for a first fight in a raid tier to be voice-acted.
That could make sense.

I might have just dreamt this up but I feel like there was an interview or a live letter translation where Yoshi-P mentioned that they would like to have the last part of the Pandemonium raid to be voiced, or at least alluded to the fact that Elidibus/Themis would have a cutscene (or several) voiced in it, but I can't say for sure.
