Rosetta Code is a revolutionary AI-powered multilingual improv comedy show.Performed in nine languages, with live translation, by an international troupe with actors present both on stage and connecting remotely, our comedy of speech-recognition errors premiered at the Rich Mix in 2019 as part of the Voil! Europe festival and developed as a tele-immersive show for the Online Paris Fringe 2020.Our company, Improbotics, includes professional actors and an artificial intelligence-based robot. Our show is an arts-meet-science interdisciplinary exploration of how actors can bridge physical and linguistic borders, communicate in multiple languages and seamlessly perform while controlled by a machine. Our impossible challenge relies on absurdism, resourcefulness and human connection.
