Patent ID: 11922927
Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 3:
4. A learning data generation device for generating learning data for learning an end-of talk prediction model, the learning data generation device comprising:
a computer configured to:
acquire utterance information on a first utterance in a dialog;
predict whether the first utterance of the dialog is an end-of-talk utterance of the speaker using a machine learning model;
detect, after acquiring the first utterance, occurrence of an interruption utterance, wherein the interruption utterance is uttered by a first speaker of the first utterance, and the interruption utterance is emitted during a second utterance by a second speaker other than the first speaker of the first utterance;
automatically generate, when detecting the occurrence of the interruption utterance within a prescribed time from the start of the second utterance, learning data for machine learning to which training data indicating that the first utterance is not an end-of-talk utterance is appended, wherein the end-of-talk prediction model, based on the learning data, recognizes an end of the utterance when the first prediction of the utterance indicates not an end-of-talk utterance and the second prediction of the utterance indicates an end-of-talk utterance.
