Spoken dialogue systems are classified into three types from the viewpoint of turn taking. Dialogue can be led by the system (system initiative), the user (user initiative), and their mixture (mixed initiative). In this paper, EUROPA, a framework for developing spoken dialogue systems, is introduced. EUROPA is applied to prototyping a car navigation system called MINOS-II. MINOS-II deals with a car navigation task of mixed initiative dialogue. First, the system takes the initiative to lead the user to set a route for the destination. Next, while driving along the route, the user takes the initiative and retrieves information about the route freely. MINOS-II is built on a portable PC, can process over 2 million sentence patterns, and is able to respond to a user's question within a few seconds.
