I am trying to find a role model as I improve my voice tone and delivery. I wonder if anybody focused on vocal tone and delivery for a while and who were you role models?

The reason I ask is that I know what my voice sounds like. It has a little bit of nasal sound, and is a bit brassy. It sounds good to me, but I am not sure where other people consider it good. It seems to me that voice tone is like fashion, your voice tone is judged by how others perceive it, not necessarily how you perceive it.
