My wife jokes that she married me so she can hear me talk :) When she asked me to narrate for the Christmas cantata she did with her church choir a few years ago, many people came up afterwards and asked if I do it for a living. In 2007 I was working for a community medical facility and would occasionally have to page someone. Soon people were commenting that they loved hearing my voice on the PA, and rather than page people themselves, they started calling me to do the page for them. Once again, there were comments that I should work at an airport, as a radio announcer or something more professional like that.
So while I have no professional voice over experience, people like to hear my voice. That is why I'm venturing into the voice over arena looking to gain some experience and see where it goes.
My wife and I run a monthly church program where I am often the main speaker. So I have extensive public speaking experience, and do 15-20 minute presentations on a regular basis.
