The disembodied voice telling you to "step back, doors closing," belongs to Virginia resident Randi Miller.
It's pretty safe to say you wouldn't recognize Randi Miller if you saw her on the street. But if she opened her mouth, you might hear something familiar in her voice, like perhaps you've heard it before.
In all likelihood, you've heard it hundreds of times, maybe thousands.
Yes, she is the "Voice of Metro." Take a couple minutes to listen to Miller explain the "perks" of being a D.C. celeb:
Miller has been the voice of Metro since 2006, after winning a WMATA talent search. Her "warm yet authoritative" tone warns riders of the closing doors and encourages them to move to the center of the car upon boarding. Miller beat out 1,258 other entrants for the gig, including her late father, Charlie, who had always wanted to be a voiceover artist.
Ironically, Miller doesn't ride Metro, since there isn't a line near her home in Woodbridge, Virginia, but she made an exception for us.
