This paper presents a dialogue system in the form of an ECA that acts as a sociable and emotionally intelligent companion for the user. The system dialogue is not task-driven but is social conversation in which the user talks about his/her day at the office. During conversations the system monitors the emotional state of the user and uses that information to inform its dialogue turns. The system is able to respond to spoken interruptions by the user, for example, the user can interrupt to correct the system. The system is already fully implemented and aspects of actual output will be used to illustrate.
