A low cost personalised robot language tutor with perceptual and interaction capabilities

Robotics has impacted many domains and industries. Robotics in education has been of particular interest to researchers and educationalists through the past decade. Various studies have confirmed that robots have had a positive impact on teaching skills in various subjects. In this paper, we develop and discuss a prototype for a robot language tutor. We use various vision techniques for behavior analysis as well as speech recognition and synthesis tools to emulate a human - human interaction. Furthermore, we have conducted experiments in which participants were asked to answer several questions based on their experience with the robot. The results of the user survey have been tabulated and analysed. Subsequently, in this paper, we discuss possible future avenues of research for a robot language tutor.
