In this paper, we propose an approach for designing the confirmation strategies in a Railway Information system for Spanish, based on confidence measures obtained from recognition. We also present several error recover and user modelling techniques incorporated in this system. In the field evaluation, it is shown that more than 60% of the confirmations were implicit ones. This kind of confirmations, in combination with fast error recover and user modelling techniques, makes the dialogue faster, obtaining a mean call duration of 204 seconds.
