Of the 30 plus jobs I have booked as a voice over artist or voice over talent, 2/3rd of them have been announcer roles, but have varied, of course, depending on the needs of the client. I pride myself on making good adjustments in the booth and being able to change the timbre, tone and depth of my voice accordingly.
My vocal range goes from deep "announcery" to light and uptone and tempo to quiet, everyday conversational. I list those three by way of example, as I have recorded, in the past six months alone, jobs requiring each.
Additionally, I do the promo's for Bloomberg TV (cited below) and have a recurring character in the animated Teenage Mutant Ninja Turtles. I have also booked more "regular guy" scripts with more character reads in the past year.
