چکیده

This report describes the conversational system designed at the University of Trento for the Evalita 2009 Spoken Dialogue Systems (SDS) Evaluation task. The main features supporting the UNITN SDS are the mixed initiative control, which allows the caller to get partly in control of the dialog strategy, and the descriptive specification of dialog strategies. The application is based on a complex, high-recall grammar and a user goal planning script. The latter is tightly bound to the grammar and provides functionalities of error checking and recovery from missing or misinterpreted concepts (Automatic Speech Recognition and Spoken Language Understanding errors).
