System of interjection reactions to maintain communication by a companion robot

The article presents a classification of interjections developed to describe a wide range of interjection reactions in a multimodal corpus, as well as aimed to be applied by companion robots that communicate through speech and gestures.As part of the study, an experiment was conducted to test part of the developed classification.In the experiment, the F-2 robot used interjections (and accompanying gestures) from the developed classification, as well as, for comparison, automatically synthesized interjections.The accuracy of human recognition of the illocutionary force of interjections was assessed.The conducted experiment showed that the level of understanding of the interjection reactions developed within this work is higher than the level of understanding of automated reactions.The results of the experiment confirmed the effectiveness of the developed classification of interjections in the framework of communication between a robot and a user.
