Why the difference in approach? Lots of my e‑learning and corporate jobs are done for production houses that will be adding other voices to the mix. Ironically, if I record my voice via a great mic and preamp, and add some nice processing, it can end up standing out from the other voices, drawing attention to itself. The production house will see this as me causing them a problem, even though my recording sounds better than the others!
No place is totally silent, so find the best place you can — even if that means thinking outside the box. I have a friend who regularly records his podcast in his car. He lives in a small house with dogs and kids, so there really isn’t anywhere else quiet enough. He takes his laptop and mic out to his driveway, shuts himself in the car and records. The results are surprisingly good!
One of my favorite things about being a voice-over actor is the incredibly supportive community. Use your community to communicate with other voice-over actors regarding rates and best business practices. I have rarely found anyone who is secretive or not willing to share their past experiences. By being a generous and communicative community, we are stronger as voice actors and can advocate for ourselves to get paid appropriately. If you are operating from a home studio and all communication is between yourself and the client (versus an agent as the intermediary) it’s usually your responsibility to invoice after sending your VO files. I always include a polite 30-day payment term at the bottom of my invoice. In certain states (for example, New York) there is a “Freelancing isn’t Free Act”, in which you can politely mention to be paid in a timely manner.
A demo recording of you doing voice-over work is your CV and your business card combined. If you're applying for a voice-over job, you can send the potential customer your demo via the Internet. Ideally you have multiple demos for different types of gigs. For commercials, clients want to hear 60 to 90 seconds of voice work. If you're auditioning as an audiobook reader, five minutes of demo proves that you can stay in character over a longer stretch of time.
