MINOS-II: a prototype car navigation system with mixed initiative turn taking dialogue
نویسندگان
چکیده
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.

The transition from system-directed to mixed-initiative human-machine dialogue has been a focus of several research institutes and industries during the past several years [4,5]. The term “mixedinitiative” was introduced in the artificial intelligence literature by Jaime Carbonell, who described a prototype that “is capable of maintaining a mixed initiative dialogue with the student, with quest...

Voice interfaces are not popular since they are neither useful nor user-friendly for non-specialist users. In this paper, EUROPA, a new framework for developing spoken dialogue systems, is introduced. In developing EUROPA, the authors focused on three points : (1) acceptance of spoken language, (2) portability in terms of domain and task, and (3) practical performance of the applied system. The...

In this paper, we outline a data driven approach to mixed initiative dialogue in acoustic user interfaces to databases. We present the knowledge sources that our dialogue planning algorithm needs: the dialogue model, the dialogue history, and the application description. Further, we discuss how the notions of taking, keeping, giving, and relinquishing the turn are reflected in our approach and ...

This paper discusses how to build a system that can engage in a mixed-initiative human-machine spoken dialogue in which system utterances sometimes overlap with user utterances and vice versa. In the method, a module that incrementally understands user utterances and another module that incrementally generates system utterances work in parallel, and the timing of taking and releasing the dialog...
متن کاملDevelopment of the HRL Route Navigation Dialogue System
In this paper we report on our work on a prototype route navigation dialogue system for use in a vehicle. The system delivers spoken turn-by-turn directions, and has been developed to accept naturally phrased navigation queries, as part of our overall effort to create an in-vehicle information system which delivers information as requested while placing minimal cognitive load on the driver.
