In this paper we present Saybot Player, an application of speech technologies to help Chinese learners of English. It is a dialogue system based on a speech recognizer and a pronunciation scoring engine. We compare our approach with existing similar systems, propose metrics to evaluate such systems and give evaluation results obtained with our users in real learning situations.
