| Abstract(in English) | CALL systems that can support Japanese students to study foreign languages have been developed in recent years. We have been developing an English pronunciation training system that enables learners to evaluate their pronunciation at an articulation level by using an articulatory-feature (AF) extractor. In this paper, firstly, an English pronunciation training system that can plots articulatory manner/place of a learner's English pronunciation on an International Phonetic Alphabet (IPA) vowel-chart in real time is described. The system converts an input utterance into an AF-sequence by using multi-layer neural networks (MLNs) of the AF extractor, then the AF-sequence is converted to the coordinate on an X-Y dimensional surface and plotted on an IPA vowel-chart that can shows the correctness of his/her articulation. In the experiments of native speakers on a TIMIT corpus, satisfactory accuracy of plotting was achieved. |
