Abstract

See full text

A dialog apparatus and the like are provided which achieve a natural dialog in which topics minutely connect, starting from a user utterance, by making, after a robot's response to the user utterance, robots exchange additional questions and answers, which reflect the contents of the response, between them. A plurality of sets of four utterances, each set being made up of four sentences: an assumed user utterance sentence, a response sentence for user utterance, a subsequent utterance sentence for these sentences, and a subsequent response sentence as a unit, are stored, and, in response to input of text data corresponding to a user utterance, the dialog apparatus performs control such that any one of a plurality of agents utters, of a set of four utterances that begins with an assumed user utterance sentence which is similar to the text data corresponding to the user utterance, each of a response sentence for user utterance, a subsequent utterance sentence for these sentences, and a subsequent response sentence, different agents utter the response sentence for user utterance and the subsequent utterance sentence, and different agents utter the subsequent utterance sentence and the subsequent response sentence.
