I've yet to secure work as a voice actor, but I've trained with Taylor Korobow (director of the Voice Factory) and David Rosenthal (staff member of Kids on Camera).
I took many classes at the Voice Factory, each one focusing on a different aspect of performance, such as advertising, character, diction and accents. With David Rosenthal I also drilled repeatedly on various scripts from advertising and games.
My home setup involves a Studio Projects B1 microphone, Edirol UA-25 pre-amp, and Audacity. I'm able to provide scratch tracks, but have limited editing experience.
My greatest influences in terms of my sense of humor and where my voices come from are Looney Tunes, Firesign Theater, Monty Python, LOTS of sci-fi movies and REALLY BAD movies!
