Addressee identification for human-human-agent multiparty conversations in different proxemics
Naoya Baba, Hung‐Hsuan Huang, Yukiko Nakano · 2012
This paper proposes a method for identifying the addressee based on speech and gaze information, and shows that the proposed method can be applicable to human-human-agent multiparty conversations in different proxemics. First, we collected human-human-agent interaction in different proxemics, and by analyzing the data, we found that people spoke with a higher tone of voice and more loudly and slowly when they talked to the agent. We also confirmed that this speech style was consistent regardless of the proxemics. Then, by employing SVM, we proposed a general addressee estimation model that can be used in different proxemics, and the model achieved over 80% accuracy in 10-fold cross-validation.
