Speaker
Description
Public-speaking skills comprise a set of interrelatedabilities, including vocal delivery, linguistic appropri-ateness, and audience-oriented communication. How-ever, this multidimensionality makes it challenging toprovide individualized, high-quality feedback, particu-larly within time-constrained curricula and in contextswhere instructors lack specialized training in oral com-munication pedagogy.To address this problem, the Audience Reactor wasdeveloped. The Audience Reactor is a humanoid-likerobot that gives feedback during the user’s speech,allowing them to actively improve and see their per-formance based on the robot’s reaction. The reactionsinclude facial expressions, body colour changes, mo-tion, and sound cues and icons indicating the speechparameters most important to improving the over-all speech quality. The robot is designed to give theimpression of actively listening to the user, with thefeedback being playful to encourage its use. The algo-rithm from which the feedback is derived is a speechanalysis algorithm provided by the company AllGo-odSpeakers. A web application allows the user to seetheir progress and a more detailed speech analysisthrough the saved results from previous sessions.
