An Approach to Accent Visualisation for the Reduction of Vowel Pronunciation Errors

Abstract

In this paper, we introduce a novel mechanism for pronunciation evaluation for use in a computer-based application for the reduction of vowel errors. Unlike modern pronunciation feedback, which relies on the charts used by linguists or simply highlighting of incorrect segments, our two-dimensional maps situate the utterances produced by the learner in the context of the phonemes of the target accent.
