The Unnamed Female Announcer was the DJ for Crash FM in Burnout Revenge, Burnout Dominator and partially Burnout Paradise. Her role is pretty much the same for all the games, as she is only appearing on the first movie of Revenge/Dominator, pointing out tactics and tricks, gives advises and new features. She is not heard during gameplay at all.
In Burnout Paradise she is narrating the opening introduction when the player starts a new game from the beggining. After that DJ Atomica replaces her, never to be heard again. This could mean she either left the radio station, or she is a co-host.
In all of the games she was voiced by Jules de Jongh.
