PROBLEM TO BE SOLVED: To easily terminate interaction, even when there are many hierarchy layers in voice interaction. SOLUTION: In a scenario of a loop form, a user is asked whether the user desires escaping from a loop at a break point of the loop, or continuing the loop. When escaping from a lower layer, escaping to a layer higher by a plurality of layers is performed by one time of "No", and interaction is terminated by two times of "No". By this invention, escaping from the loop of voice interaction is easy, and interaction is easily terminated, even when there are many hierarchy layers. COPYRIGHT: (C)2008,JPO&INPIT
