| Abstract(in English) | Speech rate conversion that slows utterances is one of the promising techniques for supporting impaired hearers such as the elderly and non-native language learners. When speech rate conversion systems are applied to real-time conversations, speakers have to wait until hearers finish listening to speakers’ whole utterances. This waiting time for speaker causes degradations of conversations, specifically at turn-takings. In order to solve these problems, we developed a novel speech rate conversation system that inserts speaker’s prolonged voice to that waiting pauses and lets the speaker to hear her/his feedback voice. Then, we apply the system to three-party video-mediated conversations and evaluate speakers’ gaze behaviors during the waiting time quantitatively. The results show that the number of averted gazes is decreased for inserted voice condition compared to without voice insertion condition. Case studies also show that the speaker who addresses next speaker gives fixed gaze to the person during the waiting time for inserted voice condition, while averted gazes are observed for without voice insertion condition. Thus, we can suggest that the system solves the troubles of turn-takings. |
