In this paper, we present the interpretation and generation processes of a spoken dialogue interface for ambient intelligence. The interface is automatically created for each specific environment and the interpretation and generation vary depending on the environment and its context. These processes rely on a dialogue tree structure. Several modules process the tree structure and the context information to produce specific dialogues for the current environment state. The interface has been implemented and evaluated in an ambient intelligence environment. Satisfactory objective and subjective evaluation results are shown at the end of the paper.

2. Dialogue Interfaces In Ambient Intelligence Environments

Although the presence of sound is not an essential characteristic for an ambient intelligence environment, we consider that a spoken dialogue interface is an important aspect in the development of these environments. Speech is a common, spontaneous and simple mean of communication (Clark & Brennan, 1991). This way, although it cannot always be the best input mechanism, it is a powerful method for the development of person-computer communication environments (Karat et al., 1999). This kind of interaction provides ambient intelligence environments with a more natural and intuitive way of communication. A continuous interaction in a daily occupied highly interactive environment without the possibility of using the voice could be a considerable effort and decrease significantly the capabilities of its occupants.
