Enunciate: An internet-accessible computer-aided pronunciation training system and related user evaluations

This paper presents our group's latest progress in developing Enunciate — an online computer-aided pronunciation training (CAPT) system for Chinese learners of English. Presently, the system targets segmental pronunciation errors. It consists of an audio-enabled web interface, a speech recognizer for mispronunciation detection and diagnosis, a speech synthesizer and a viseme animator. We present a summary of the system's architecture and major interactive features. We also present statistics from evaluations by English teachers and university students who participate in pilot trials. We are also extending the system to cover suprasegmental training and mobile access.
