A Temp VA, or Temporary Voice Actor, is someone who steps in to voice a character temporarily, usually because the main VA isn’t available for the time being. While they’re not guaranteed a original role, Temp VAs are still encouraged to audition for other characters. If they audition for a character that hasn’t been cast yet, and are chosen, they will officially become part of the main cast essentially getting promoted from a temporary role to a full one with an original character.
