The BBC's Perceptive Radio uses local data and onboard sensors to adjust itself and even alter the script of a radio play in real time.

All radio scripts call for a small ensemble to play numerous characters by changing their voices, and this quintet — playing the fictitious radio performers — is expert at doing just that.

Items from Texas Rangers radio play-by-play voice Eric Nadel, including the handwritten script of his World Series-winning call, sold at auction for $13,500.
