|発明の名称||VOICE INTERACTION DEVICE AND AUTOMATIC INTERACTION METHOD EMPLOYING VOICE INTERACTION DEVICE|
PROBLEM TO BE SOLVED: To solve the problem that, it may not be clearly determined from a rhythm analyzed from a speech production of a user whether a next speed production should be performed by a robot or a speed production of the user should be awaited and, in such a case, silence may be continued between both the robot and the user or speech productions of both the robot and the user are overlapped, thereby preventing the user from enjoying a smooth conversation.
SOLUTION: A voice interaction device comprises: an estimation unit for estimating whether a next user speech production should be awaited or a speech production from the device itself should be executed based on a user speech production inputted by an input unit; and a response control unit for making a response by executing at least either filler output that causes an output unit to output a filler of a filler speech production non-associated with an interaction content or a nodding action that moves a dummy head forwards and backwards in a case where the estimation unit can estimate neither that the user speech production should be awaited nor that the speech production from the device itself should be executed.
