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

Claim 7:
8. A learning data generation method generating learning data for learning an end-of-talk prediction model, the method comprising:
acquiring utterance information on an utterance in a dialog;
automatically performing:
a first prediction in which it is predicted, based on the utterance information, using the end-of-talk prediction model, whether the utterance is an end-of-talk utterance of the speaker, and
a second prediction in which it is predicted, based on one or more prescribed rules, whether the utterance is an end-of-talk utterance, wherein the one or more prescribed rules are rules regarding a silent interval;

automatically generating, when, in the first prediction it is predicted that the utterance is not an end-of-talk utterance and in the second prediction it is predicted that the utterance is an end-of-talk utterance, for the utterance information on the utterance, learning data for machine learning of the end-of-talk prediction model to which training data indicating that the utterance is an end-of-talk utterance is appended, wherein the learning data is used to improve the prediction error of the end-of-talk model based on the prediction result of the second prediction.
