The “Actors Challenge” Project. Collecting data on intonation profiles via a web game

This paper describes ”Actors Challenge”, a soon-to-go-public web game where the players alternate in the double role of actors and judges of other players’ acted-out utterances, and in the process create an oral dataset of prosodic contours that can disambiguate textually identical utterances in different contexts. The game is undergoing alpha testing and should be deployed within a few months. We discuss the need, the core mechanism and the challenges ahead.
