Did amateur home recordings with friends when younger, creating stories, spoofs of commercials, and "news" announcements.
Have done a considerable amount of public speaking, and am often told I have a great speaking voice.
On the telephone, people (usually women) who don't even know me often compliment me on my voice.
I have not had professional voice over training or education, but again, I have done a large amount of public speaking, and also narration. I have sung in the choir and also done readings at my church, and have often been complimented on my voice.
My father was a journalism and communications professor at a California university, and often counseled me that I should practice with my voice to be a radio announcer or something similar.
I am also a creative writer, and have practiced narrating some of the stories I have written. These have largely been fictional, some science fiction, some drama.
I have an intense interest in astronomy, and have often contemplated what it would be like to narrate astronomy- and space-themed stories or shows, such as was done by Carl Sagan. Providing narration or other voice over for a project with an astronomy/space theme would be very exciting.
