Didn't they used to teach diction in school? I could have used some of that training, but was instead a victim of the upstate New York accent for many years. I know I have to talk slower in order to not slur too many words when I talk, and speaking with a confident tone doesn't come natural to me (avoiding that rising inflection thing). I also struggle to not sound monotone and dry. And, furthermore, when I've heard recordings of myself I feel like I sound like I'm always ready to say something smart or sarcastic.
