5th International Conference on Spoken Language Processing
In this paper we report on the development of a spoken dialogue system for computer aided language learning (CALL), and explore some of the issues involved in the incorporation of a corrective feedback module. We initially developed a small prototype system, and tested it for usability with visiting students of English as a foreign language. In the light of the positive results we obtained for this, we began to develop a more advanced system, with the aim of investigating how spoken dialogue systems might best be tailored to help language learning. The issue we focussed on was the kind of feedback on errors which might be most useful to the learner. We show the types of feedback we have considered, and highlight some of the problems associated with providing different types of feedback.
