Audio Puzzler: piecing together time-stamped speech transcripts with a puzzle game.

We have developed an audio-based casual puzzle game which produces a time-stamped transcription of spoken audio as a by-product of play. Our evaluation of the game indicates that it is both fun and challenging. The transcripts generated using the game are more accurate than those produced using a standard automatic transcription system and the time-stamps of words are within several hundred milliseconds of ground truth.
