INTERACTION SYSTEM, INTERACTION METHOD, AND PROGRAM

The present disclosure provides an interaction system, an interaction method, and a program capable of making a user form an attachment to a particular interaction model. A first interaction model (100) is configured so that a communication function expressed to a user is improved from an initial state through communication with the user. A second interaction model (200) is configured to interactwith the user by a communication function better than the initial state of the first interaction model (100), and to make a speech for the user, the speech being made so as to support the improvementof the communication function of the first interaction model (100). 本发明提供一种能够使用户对特定对话模型形成依恋的对话系统、对话方法及程序。第一对话模型(100)构成为，通过与用户的沟通，向用户表现出的沟通功能从初始状态不断提高。第二对话模型(200)构成为，利用比第一对话模型(100)的初始状态更为良好的沟通功能与用户进行对话，而向用户进行辅助第一对话模型(100)的沟通功能的提高的发话。
