Stephanie has written some thoughtful comments at the Vox Daily voiceover blog about studying with a voiceover coach. There are several good voiceover coaches. If you’ve been reading here for a few weeks, you know that my first and highest recommendation for a voiceover coach is Nancy Wolfson. She works with folks in Southern California in person and with people like me who live in other parts of the world over the phone.
In the interests of full disclosure, if you decide to study with Nancy and you mention that you are doing so because of what you read here, she’s going to give me a free lesson.
(Update: If you are or know a voiceover coach based in Canada, Stephanie is looking for contact information. Check out her post here.)
