This paper presents a generic web-based dialogue game framework, Mercurial, for language learning. The system capabilities are demonstrated within a flight domain application. The system randomly generates a flight-booking scenario according to the current difficulty level. The student accomplishes the scenario by interacting with the system through speech. The system gives real-time feedback on the dialogue progress and scores, and summarizes the whole dialogue at the end of each scenario. The system uses generic language understanding, language generation, dialogue management, and user simulation modules to conduct the dialogue and give contextual help. Preliminary experiments yielded positive feedback from the subjects.
