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.

Claims

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.
