Davinadroid

The Davinadroid was a robotic voice that controlled the Big Brother house aboard the Game Station. It welcomed the Ninth Doctor to the Diary Room, informing him he was on live television Channel 44000 and asking him to refrain from swearing. (TV: Bad Wolf)

Behind the scenes
The droid's name is a pun on that of Davina McCall, the host of the show at the time of Bad Wolf's broadcast. McCall voiced the Davinadroid in Bad Wolf.
