This corpus contains data from a laboratory experiment with 60 adults (30 pairs) playing an interactive word guessing game called Taboo. Two players switched roles, giving clues, or guessing, half the time. The game had four rounds of ten trials each, generating 40 trials per session. Clue-givers stood on a wobble board or the ground, with this manipulation influencing their postural stability. While the pairs were playing the game of Taboo, they were recorded using multiple camera angles (front and side), lapel microphones, and a gyroscope attached to the wobble board. Clue-giver and guesser speech was transcribed in detail at the trial-level and transcripts are part of the corpus.
