How much is accent influenced by the successful individuals within a language group?

This is going to sound conceited, so brace yourself, it is not meant to be so. I am effective. Let’s just put it that way.

As an effective person, I know that others around me have changed their voices to sound more like mine.

I am flattered. But, I think that this might not only work in my microcosm, but in a dialect at large.

As a testament to the opposite of what I am saying: If one’s voice makes one sound weak, I believe that others would not emulate you.

What do you think?

When we speak are we hearing the voice of the successful individual?
