Dialogue robot, dialogue system, and dialogue program

Abstract

The invention is to provide a dialogue robot, a dialogue system and a dialogue program with which natural dialogue with a user can be achieved. This dialogue robot i) receives answer sentence information generated by a server and including a name question for asking the name of a user if the server identifies, on the basis of facial information of the user, that the user is unregistered, and ii) receives answer sentence information generated by the server and including the name of the user if the server identifies, on the basis of the facial information, that the user is registered, and a voice production unit performs, with respect to the user, a start utterance including the name question or the name of the user according to whether the user has already been registered or not. Moreover,this dialogue robot is able to arbitrarily change the level of conversation with the user, and further may execute preprocessing such as various inquiries before changing the set level.

Description

technical field [0001] The present invention relates to technologies using interactive robots, and more specifically relates to interactive robots, interactive systems, and interactive programs that can actively communicate with various modes of voice while watching the user's facial expressions. Background technique [0002] Due to the advancement of information means, opportunities to communicate with foreigners in foreign languages ​​are increasing. In addition, due to the advancement of transportation means, it has become an era where it is easy to travel abroad, and opportunities to understand and speak the language of the destination country are also increasing. Therefore, the learning of foreign languages ​​including English, especially the learning of conversational skills, is very important no matter what age. [0003] In recent years, with the development of communication technologies such as the Internet, various technologies for performing simulation sessions vi...

Problems solved by technology

In this regard, for example, if the conversational robot proposed in Patent Document 2 is improved to have a huge amount of information, although a more human-like dialogue can be realized, the processing operation may be delayed, and the price of the robot itself will be very expensive.

[0015] In this way, in the prior art including the above-mentioned patent documents, it is impossible to realize the level of natural conversation with the user (as if human beings are talking to each other) without increasing the cost, and there is still a lot of room for improvement.
