- Abstract
- This paper introduces a way of enhancing automatic speech recognition
systems in processing non-native speakers utterances. The key procedure is to
design and provide an English pronunciation dictionary which includes frequent
error pronunciations by Korean learners as if they were regular pronunciation
variations. First, knowledge-based rules are collected to generate as many nonnative
variants as possible. Then the relative frequency of each variant is
measured to select more frequent error-variants while discarding rare ones. In
automatic recognition experiments with this dictionary, it is found that the word
recognition performance increases considerably for Korean learners incorrect
pronunciation. Although utterances by Korean learners of English are the main
target data of the current study, the proposed method is expected to be further
available in other language environments.
