Streamers and youtubers these days can be a HUGE part of the popularity of a release and the thing is: they absolutely hate to read dialogues aloud when playing for their audience. I never tried to stream anything myself, but to be honest, I can't really blame them. I would hate doing it, too.
Ya, I know exactly one youtuber who has enough guts to read everything or almost everything. Others (nice ones) just scroll down so viewers can pause. Streamers are another world beings, hurry as much they can. Personally, I can read my part but companions and NPCs should be voiced.
