| Abstract(in English) | For the purpose of automating the prosodic evaluation of English words spoken by Japanese learners, we have been focusing upon the automatic detection of stressed syllables in English words by using HMMs. In this study, we compared HMMs, DP matching, and human eyes, not ears, in terms of their performance of judging whether two utterances of a single word have the same stress pattern or not. The latter two methods of the judgment were examined because they are conventional methods or have been used in the commercial software for language learning. In the judgment experiment, two kinds of word pair utterances were prepared. One was those which should be judged to have an identical stress patternand the other was those which should not. And the number of the word pairs were the same between the two. Results showed that the performance was the highest in HMMs though the other two methods utilized additional schemes for the performance improvement. Considering that the judgment by using HMMs give us additional information on the location of the stressed syllables, this study showed the high validity of using HMMs in developing the techniques for prosodically evaluating English words and sentences spoken by non-native speakers. |
