Addressing Confusions in Spoken Language in ESL Pronunciation Tutors

چکیده
This paper presents a new approach for developing pronunciation tutors in Second Language (L2) learning. Applying the Basic Identification of Confusable Contexts (BICC) procedure we automatically generate curriculum that is rich in possible confusion contexts which can be practiced by L2 students in read-aloud tasks. This is the basis of a new pronunciation tutor where the student interacts orally in a scripted conversation with a virtual avatar. The student’s utterances are automatically evaluated to detect mispronunciations and the tutor provides feedback on the errors which produce a confusion in the message. An assessment was carried out with a group of English as Second Language (ESL) speakers to evaluate the tutor interface as well as to determine their motivation and engagement in practicing English with it.

متن کاملAugmenting Translation Models with Simulated Acoustic Confusions for Improved Spoken Language Translation
We propose a novel technique for adapting text-based statistical machine translation to deal with input from automatic speech recognition in spoken language translation tasks. We simulate likely misrecognition errors using only a source language pronunciation dictionary and language model (i.e., without an acoustic model), and use these to augment the phrase table of a standard MT system. The a...
