My vision for this was a button on the quest mission text box that triggers the tts. Perhaps it could be done via an overlay, even, that could be used in multiple games? I guess it might have benefits, too, for partially sighted people in other respects (reading documents and such) but I guess those solutions already exist.
Hearing chatter from people on the streets of Paragon seems more complex, but not impossible. I'd certainly opt in, given that option.

Here comes realistic voice synthesis. Thanks, Voice Actors, your work was appreciated - and now kindly stand aside. The robots are here to take the creative jobs and leave the boring repetitive stuff to the humans. This isn't how it was supposed to be!!!1111 Curse you and your alternate reality, Cole!
