NPR's All Things Considered interviewed Reed Summers
, winner of a "Mouth Sounds" competition in Belleville, Illinois.
Summers explained that "mouth sounders" use their mouth, tongue, teeth, lips, and vocal chords to create a variety of sounds, such as the sound of an angry cockatoo, a goose, a train, and Bach's Toccata — all of which he demonstrated in the studio.
As the interview with Summers progressed, the sounds he made grew increasingly elaborate and realistic, causing host Robert Siegel eventually to declare, "If I hadn't seen you doing that in front of me just now, I would have assumed that was a recording."
Summers attributed his mouth-sounding skill to the fact that he didn't speak until he reached the age of 10, but instead spent his childhood listening to the sounds around him.
