摘要： A communication skill evaluation system including: an audio input device; a measurement device; an utterance period detection unit that, based on the audio information input by the audio input device, detects an utterance period and a participant who spoke in each utterance period; a participatory role assignment unit that assigns a participatory role to each participant in accordance with whether or not each participant spoke in each utterance pair composed of two utterances obtained in chronological order from each utterance period; a feature quantity extraction unit that, based on the measurement results by the measurement device, extracts a non-verbal feature quantity for each participant, relating to the non-verbal action at the end of the utterance in each utterance period; and an estimation unit that estimates communication skill for each participant based on a combination, in each utterance period, of the participatory role and the non-verbal feature quantity.

摘要： In communication performed among multiple participants, at least one of a participant who will start speaking next and a timing thereof is estimated.
An estimation apparatus includes a head motion information generation unit that acquires head motion information representing head motions of communication participants in a time segment corresponding to an end time of an utterance segment and synchronization information for head motions between the communication participants, and an estimation unit that estimates at least one of the speaker of the next utterance segment following the utterance segment and the next utterance start timing following the utterance segment based on the head motion information and the synchronization information for the head motions between the communication participants.

摘要： A nonverbal information generation apparatus includes a nonverbal information generation unit that generates time-information-stamped nonverbal information that corresponds to time-information-stamped text feature quantities on the basis of the time-information-stamped text feature quantities and a learned nonverbal information generation model. The time-information-stamped text feature quantities are configured to include feature quantities that have been extracted from text and time information representing times assigned to predetermined units of the text. The nonverbal information is information for controlling an expression unit that expresses behavior that corresponds to the text.
