Abstract

A conversation analysis device includes an utterance data acquisition unit that acquires utterance data representing a voice of each speaker and an utterance of the speaker, a speech state analysis unit that analyzes a speech state of each speaker on the basis of the voice, and a degree-of-contribution calculation unit that calculates a degree of contribution to the conversation of each speaker on the basis of the speech state.

First claim

What is claimed is:

1 . A conversation analysis device comprising:
an utterance data acquisition unit that acquires utterance data representing a voice of each speaker and an utterance of the speaker; a speech state analysis unit that analyzes a speech state of each speaker on the basis of the voice; and a degree-of-contribution calculation unit that calculates a degree of contribution to the conversation of each speaker on the basis of the speech state.

2 . The conversation analysis device according to claim 1 ,
wherein the speech state analysis unit includes a degree-of-activity calculation unit that calculates a degree of activity in the conversation on the basis of an utterance time as the speech state.

3 . The conversation analysis device according to claim 1 ,
wherein the speech state analysis unit includes an interruption determination unit that determines interruption of an utterance of another speaker as the speech state.

4 . The conversation analysis device according to claim 1 ,
wherein the speech state analysis unit includes a conclusion mention determination unit that determines an utterance mentioning an element of a conclusion of the conversation as the speech state.

5 . The conversation analysis device according to claim 1 , comprising:
a conversation evaluation unit that calculates an evaluation value indicating a contribution state between speakers in the conversation on the basis of the degree of contribution of each speaker.

6 . The conversation analysis device according to claim 1 , comprising:
an utterance data analysis unit that specifies an utterance including a section in which activity of the utterance is higher than a predetermined threshold of the activity in the utterance data.

7 . A conversation analysis method in a conversation analysis device, comprising:
an utterance data acquisition step of acquiring utterance data representing a voice of each speaker and an utterance of the speaker; a speech state analysis step of analyzing a speech state of each speaker on the basis of the voice; and a degree-of-contribution calculation step of calculating a degree of contribution to the conversation of each speaker on the basis of the speech state.

8 . A computer-readable non-transitory recording medium including a program for causing a computer of a conversation analysis device to execute:
an utterance data acquisition process of acquiring utterance data representing a voice of each speaker and an utterance of the speaker; a speech state analysis process of analyzing a speech state of each speaker on the basis of the voice; and a degree-of-contribution calculation process of calculating a degree of contribution to the conversation of each speaker on the basis of the speech state.
