This study examines automatic prediction of the words that will be unintelligible if they are spoken by Japanese speakers of English. In our previous study [1], 800 English utterances spoken by Japanese speakers, which contained 6,063 words, were presented to 173 American listeners and correct perception rate was obtained for each spoken word. By using the results, in this study, we define the words that are very unintelligible through Japanese accented English pronunciation and also define the words that are rather unintelligible. Then, by using Classification And Regression Tree (CART) with linguistic features and lexical features only, we examine automatic detection of these words. After that, we introduce an additional feature derived by considering phonological and phonotactic differences between Japanese and English, and another feature derived by calculating the phonetic pronunciation distance observed from manually-annotated IPA transcriptions of Japanese English and American English. This additional features are found to be very effective and our proposed method can detect very unintelligible words and rather unintelligible words automatically with F1-scores of 69.56 and 78.36 [%], respectively, if phonetic transcriptions are given. |
