system in which a terminal and a voice conversation generation device that is a control device communicate with each other via a network, the voice conversation generation device 16 includes a voice conversation AI that is executed using a predetermined
scenario program 50 and an interactive-type generation function
execution unit 52 that assists the progress of the
scenario program, and receives an answer from a user by providing the user with a question for extracting information related to a specific theme that prompts the user to recall a personal history, and a recall information and
summary information storage unit 62 that accumulates a plurality of pieces of recall information of the user acquired by repeating the voice conversation function. The
scenario program instructs the interactive-type generating AI executing unit to execute a free conversation that includes at least simple response, sympathy, and synchronization for increasing the amount of speech from the user, and that follows the user who is the conversation partner.SELECTED DRAWING: Figure 3
