ACIMET* (ACcés a Informació Meteorològica per Telèfon) is a real service that gives access to automatically gathered meteorological information by using the human language technology available in TALP center for the Catalan language. The service is addressed to Catalan tourists, for leisure purposes and professionals with a need for immediate, and accurate meteo data (i.e. civil defense). Users request data by establishing a natural, oral dialogue by means of a phone call. The system also provides a warning and alarm service: the user will be informed through a phone call or an SMS whenever certain meteorological conditions take place. The oral dialogue system is evaluated with the PARADISE framework.
