Simulations showing the audiovisual speech performed by Furhat during the second language tutoring experiment. Each video consists of the Furhat saying a Dutch word, followed by saying the Japanese translation twice. Videos M1-M10 correspond to the Matched condition, M11-M20 to Mismatched, and M21-M30 to the Computer-generated lip movement. In the experiment, participants interacted with a physical Furhat, but as it is difficult to make video recordings of the Furhat, simulations are shown here to allow for high-fidelity comparison between conditions.
