Abstract: An information processing terminal according to the present disclosure includes a control unit (100) that performs a process of transmitting inquiry information on a specific device to a server on the basis of a spoken content of a user or a state of the specific device that is voluntarily collected, a process of outputting answer information when receiving, from the server, the answer information based on an answer database in which answer information prepared in advance is registered, and a process of making an inquiry to an operator with respect to the inquiry information if the answer information is not detected in the server.

Abstract: A control section performs control to give notification of information regarding a previous dialogue on the basis of each status of participants in dialogue. For example, the information regarding the previous dialogue includes information regarding a significant word extracted from a speech of the previous dialogue. In this case, the information regarding the previous dialogue further includes, for example, additional information related to the significant word. For example, when one of utterers currently in dialogue makes an utterance indicative of intention to call up information, the control section perform control to give notification of the information regarding a previous dialogue in which all utterers currently in dialogue participated.
