voisTUTOR: Virtual Operator for Interactive Spoken English TUTORing

Chiranjeevi Yarra, Prasanta Kumar Ghosh


Second language (L2) learners of English could improve their pronunciation using automatic tutoring apps that provide detailed feedback. However, the availability of such apps are very few and, at most, the feedback from those apps are limited in the sense that they provide a minimal feedback for improving correct usage of phonemes. But, to achieve better pronunciation quality, the L2 learners are required to correctly place stress, intonation and pauses in their spoken utterances. In this demo, we present a self learning app called voisTUTOR that provide more detailed feedback on correct usage of phonemes as well as stress, intonation and pauses. In this app, the feedback is provided specific to each of these four categories by showing a score representing learner's quality as well as their mismatches with respect to expert's pronunciation. We believe that this app could be useful to the learners who do not have easy access to effective spoken English training.
