A Wizard-of-Oz game for collecting emotional audio data in a children-robot interaction

Abstract

In this paper, we focus on the recording protocol for gathering emotional audio data during interactions between the Nao robot and children. The robot is operated by a Wizard-of-Oz, according to strategies meant to elicit vocal expressions of emotions in children. These recordings will provide data to develop a real-time emotion detection module for the robot, and will be a starting point for a study on emotional models of exchanges in the interaction with a robot. This work is carried out in the context of the French ROMEO project meant to design a robot which will be able to interact with people (children, elder people), taking into account the behavior of the person. Two kinds of application are studied in this project: the robot acts as a game companion or as an assistant to disabled persons.
