>>8184276That's what I would do. I like to practice diction and it feels like a natural element to read dialogue like I think they would say it.
Maybe a better way would be to use some kind of media that has audio in it, a movie is probably best, and mimic emotional monologues. I find that an emotional register can "click" for me if I do this. It's important to remember that you should only try this with... good actors doing good acting. There are a lot of movies where it's pretty clear the actor is playing a role that makes their motivations really confusing or one dimensional.
I'm not suggesting you talk like that all the time, but if I mimic something well enough I physically feel an emotion and that helps me hone in on it later. It's all about reps, and you gotta get a diet with a wide variety of feels if you want to express them (in a measured and controlled fashion while also accounting for quality control).
