Dee Bradley Baker is one of the best voiceover actors working today…as proven by the fact that the two times I tried to hire him, he was busy working for someone else and unavailable. If you are interested in this occupation either as an onlooker or as someone who wants into the profession, you should read his list of Dos and Don'ts for auditions. For that matter, you should read his entire site. There are coaches out there who will try and charge you a fortune to learn the things Dee is giving away for free there.
