The voice actors are going to be the ones providing voices to the series, both in the way of the stories that will be read, and the original story that will accompany it.  Slate your audition. This means say your name and the story you're reading. Keep your audition between one to three minutes long. Also, show that you can do multiple unique character voices. A lot of voice actors will be brought on, so if you audition, there's a pretty high chance you'll get casted.
