| Outline of Final Research Achievements |
The following research was conducted as planned in the research proposal. As for Japanese, 1) Systematic difference of voice quality was found between the vowels in filled pauses and ordinary lexical items. As for English, 2) factors affecting the probability of filled pauses in clause-initial position were extracted, and 3) differences of filled-pause usage between the English native speakers and Japanese learners of English were extracted, and analyzed with respect to proficiency levels of the learners. As for Chinese, 4) the same analysis as in 1) above revealed basically the same results as in Japanese, but language-dependent differences were also found with respect to the change in the vowel color, for example. Lastly, 5) a new computational algorithm that can enable reliable extraction of the speech fundamental frequency (F0) information from the vowels having strongly creaky and/or breathy voice qualities.
