VOICE CONVERSATION DEVICE, CONVERSATION CONTROL METHOD, AND CONVERSATION CONTROL PROGRAM

摘要

A voice conversation device, a conversation control method, and a conversation control program which are not affected by an accidental conversational behavior made only once by a user but accurately determines the learning level of the user's conversational behaviors, thereby appropriately controlling the conversation according to the learning level determined accurately. An input means (1) inputs a voice let out by the user. An extraction means (3) extracts the determination factors of the learning level on the basis of the result of the voice input by the input means (1). A history accumulation means (4) accumulates as histories the determination factors of the learning level extracted by the extraction means (3). A learning level determination means (5) determines the convergence state of the determination factors of the learning level on the basis of the histories accumulated by the history accumulation means (4), determining the learning level of the user's conversational behaviors on the basis of the determined convergence state. A conversation control means (6) varies the conversation control according to the user's learning level determined by the learning level determination means (5).
