Conversation analysis device and conversation analysis method

A conversation analysis method performed by at least one computer, the method comprising:

• detecting a plurality of predetermined transition patterns of an emotional state on a basis of data related to a voice in a target conversation, with respect to each of a plurality of conversation participants;
• identifying a start point combination and an end point combination on a basis of the plurality of predetermined transition patterns detected, the start point combination and the end point combination each being a predetermined combination of the predetermined transition patterns of the plurality of conversation participants that satisfy a predetermined positional condition;
• and
• determining a start time and an end time of a specific emotion section representing a specific emotion of the participant of the target conversation, on a basis of a temporal position of the start point combination and the end point combination identified in the target conversation.

A conversation analysis device comprising:

• a transition detection means for detecting a plurality of predetermined transition patterns of an emotional state on a basis of data related to a voice in a target conversation, with respect to each of a plurality of conversation participants;
• an identification means for identifying a start point combination and an end point combination on a basis of the plurality of predetermined transition patterns detected by the transition detection means, the start point combination and the end point combination each being a predetermined combination of the predetermined transition patterns of the plurality of conversation participants that satisfy a predetermined positional condition;
• and
• a section determination means for determining a start time and an end time on a basis of a temporal position of the start point combination and the end point combination identified by the identification means in the target conversation, to thereby determine a specific emotion section defined by the start time and the end time and representing a specific emotion of the participant of the target conversation.
