Abstract

In this paper, we describe the steps carried out for developing a Railway Information Service for Spanish. This work introduces a methodology for designing dialogue managers in spoken dialogue systems for restricted domains. In this methodology several sources of information are combined: intuition, observation and simulation for defining several dialogue strategies, evaluating them and choosing the best. Users in a final evaluation gave the system a 3.9 score in a 5-point scale with an average call duration of 204 s.
