The system contains a generalised mechanism for generating utterances and dialogues, drawing on a sociolinguistics theory of politeness. It combines a Spoken Language Generator (using full NLG techniques) with an AI planner to model linguistic politeness in collaborative task oriented dialogue with the ultimate goal of providing a stimulating environment and a fun way for learning politeness in English as a Second Language (ESL).

Dialogues are demonstrated within Embodied Conversational Agents (ECA) capable of dialogues with human ESL learners, interacting with them using spoken language to practice politeness in role play situations.
