Abstract
This paper proposes a practical robotic interface that has tolerant behaviors of voice recognition error. Recently, a robotic interface attracts people's attention as an intermediary between complicated information home appliance and its user. The user wants to operate the appliances by voice. The problem of robot the voice recognition is difficult especially at home and by inexperienced users. We think if the robot acts like an infant, the user will accept recognition error by the robot. Based on this idea, we innovate infant's familiar behaviors to the robotic interface. This paper reports the effects of the familiar behaviors installed in two kinds of robots in the different shapes.
