As we start 2015 we know anything can happen. This includes you having a voiceover career. I get a lot of emails, a lot of inquiries on Twitter @masteringVO regarding starting a VO career. Most of the questions have to do with how competitive it is and how difficult the training might be.
EVERYTHING is competitive and everything requires lots of training. Any career takes time to learn and has professional standards that have to be met. If it didn't take a high level of vocal skill, no one would work at Sears. Control over tone of voice, breathing, nuance, and an ability to vary cadences to solve problems of meaning and/or articulation, take time and practice. If you wanted to be a lawyer, a teacher, a dentist, a plumber or a sales person, you would have to commit your time and money to have a career. The real question isn't how competitive or difficult it is, the real question is do you want to be a voiceover artist? You can do it if you feel it's the path for you. If your friends tell you it's impossible get new friends:) It is wonderful fun to do things that others think can't be done.
