Dialog supporting device

Abstract

A dialog supporting device supporting improved dialog by reducing the number of utterances resulting from misunderstandings and hasty conclusions. The dialog supporting device includes: an example database which holds examples used in the dialog; an utterance receiving unit which receives utterances of a user and outputs the utterances as utterance information; an example selecting unit which sequentially selects examples most similar to the utterance information from the example database, and obtains translated examples corresponding to the examples; an utterance difference calculating unit which calculates a difference between the utterance information and the example selected by said example selecting unit and obtains difference information representing the difference; a sending unit which sends, to a dialog supporting device of a dialog partner, the example obtained by the example selecting unit and the difference information; a receiving unit operable to receive the example and the difference information from the dialog supporting device of the dialog partner; and an utterance outputting unit operable to output the example and the difference information received by the receiving unit.
