If you want to break out of a rut, one thing you have to do is find a different point of view. When I’m stuck while I’m writing, I’ll get up and just walk around for a few minutes. If I’m having a hard time nailing a voiceover, I’ll ask for further direction or a different characterization of who I am.
So, if you’ve been wondering why your auditions at Voices.com (formerly InteractiveVoices.com) or similar sites haven’t been producing the results you’d hoped for, you’ll find a very interesting post at VoxDaily, which includes extensive notes from a producer who had just been through the process of listening to a number of auditions. It’s right here.
There are also a bunch of comments, so it will take you a while to read through everything; but I think you’ll find the time will have been well spent.
