About the voice, I wouldn’t obsess too much over it, especially when starting out. There’s enough other stuff for beginners to work on anyway, and since you’re not going to get it 100% right right away, you might as well focus on the more obvious things that need attention while allowing your voice to come about organically. You’re working on a version of yourself, not a caricature. As long as you don’t sound like Brad Garrett, you should be ok.
