"What Do You Want to Do Next?" Providing the User with More Freedom in Adaptive Spoken Dialogue Systems

Spoken dialogue is a suitable form for user interaction in intelligent environments because of its low demands to presentation hardware (e.g. microphone and speaker set) and its low cognitive demand. That means that the user can still do something else while communicating with a spoken dialogue system (SDS). In this paper, we investigate the demands to modern SDSs in intelligent environments and how to provide the user with more freedom by using constraint programming techniques for dialogue management. For this we present an architecture which allows for adaptivity and freedom in SDSs.
