I'll be totally honest in confessing that when I graduated from drama school, I thought I knew most of the basics for voice over acting. Though the actual amount of tuition we received probably amounted to around a week, we got to work with industry professionals on a number of different scripts. On reflection however, we'd only scratched the surface.
A lot of that tuition was based in radio drama, which is the most obvious bridge to 'normal' acting. Conversations still needed to be believable, but a lot of time was (necessarily) spent learning the basics of mic proximity and getting used to talking to it rather than the person next to you. Our work with sales and narration copy - typically the bread and butter of many VO's careers - was very brief... brief enough, anyway, that I'm struggling to remember more than one or two classes on it. Beyond a basic understanding of technical requirements, there wasn't a lot of room to discuss how me might be able to apply our 'toolbox' of acting techniques to this new medium.
This is a subject I have continued to explore as I've returned to training for voice over. A lot of what's said in those classes are linked heavily with various approaches to acting, but it's been invaluable for me at this stage of my career to build those connections in my mind.
I has fortunate enough to be interviewed by Joe Murphy, another voice over who recently started full-time as well, about how my acting experience may inform my voice over product. He regularly posts interviews with people (far more experienced, interesting and concise than me) already in the industry as he tracks the progress of his career. I'd definitely recommend checking out his YouTube channel here. My interview, for what it's worth, is below.
