Abstract: Provided is a technique for generating an utterance based on data indicating the context of a dialogue.

Abstract: An object is to give the user the impression that the system has sufficient dialogue capabilities. A humanoid robot (50) presents a first system speech to elicit information regarding a user's experience in a subject contained in a dialogue. A microphone (11) accepts a first user speech spoken by a user (101) after the first system speech has been spoken. When the first user speech is a speech that contains information regarding the user's experience, the humanoid robot (50) presents a second system speech to elicit information regarding the user's evaluation of the user's experience. The microphone (11) accepts a second user speech spoken by the user (101) after the second system speech has been spoken. When the second user speech is a speech that contains the user's positive or negative evaluation, the humanoid robot (50) presents a third system speech to sympathizes with the positive or negative evaluation.

Abstract: An object is to give the user the impression that the system has sufficient dialogue capabilities. A dialogue system (100) has a personality virtually set thereto. A microphone (11) collects a spoken voice of a user (101) and converts it into a voice signal. A voice recognition unit (20) performs voice recognition on the voice signal of the spoken voice of the user (101) to convert the voice signal into a text that represents the content of the user's speech. A speech determination unit (30) determines a text representing the content of a system speech that is based at least on information contained in the most recently input user speech and information set to the personality of the dialogue system. The voice synthesis unit (40) converts the text representing the content of the system speech into a voice signal representing the content of the system speech. A speaker (51) outputs the voice signal representing the content of the system speech.

Abstract: It is an object of the present invention to prevent inattentive listening to a dialogue of an agent without taking it seriously and to make it easier to understand the dialogue with the agent. A dialogue system 100 conducts a dialogue with a user 101. A humanoid robot 50-1 presents a leap-in-logic utterance, which is an utterance, of which a logical structure is partially missing. The user 101 expresses a confirmation action which is an action confirming the missing information in the leap-in-logic utterance. The humanoid robot 50-1 presents a supplementary utterance which is an utterance describing the missing information.

Abstract: The present invention keeps a dialogue continuing for a long time without causing uncomfortable feeling to a user. A dialogue system 10 includes at least an input part 1 that receives a user utterance, which is an utterance from a user and a presentation part 5 that presents the utterance. The input part 1 receives a user utterance performed by the user. A presentation part 5-1 presents a dialogue-establishing utterance which does not include any content words. A presentation part 5-2 presents a second utterance associated with a generation target utterance, which is one or more utterances performed before user utterance that includes at least the user utterance, after the dialogue-establishing utterance.

Abstract: It is an object of the present invention to induce a dialogue to a topic that a dialogue system tries to present. A dialogue system 100 presents a first utterance which is a certain utterance and a target utterance related to the first utterance to a user 101. A humanoid robot 50-1 presents the first utterance. A microphone 11-1 receives a user utterance of the user 101 after the first utterance. A humanoid robot 50-2 presents at least one topic-inducing utterance for inducing the topic to the target utterance based on a recognition result of the user utterance and an utterance sentence of the target utterance after the user utterance. The humanoid robot 50-1 presents the target utterance after the topic-inducing utterance.

Abstract: It is an object of the present invention to provide a dialog technique that can reduce a user's uncomfortable feeling. A dialog system 100 is a dialog system that conducts a dialog with the user, the dialog system including a presentation part 50 that presents an action to fill a gap between a user utterance and a response utterance of the dialog system, after it is estimated or determined that the user utterance has ended or after a predicted time at which the user utterance ends, and before the dialog system makes a response utterance to the user utterance.
