| Research Abstract |
The first half of the three-year research project was devoted for the derivation of new research data from the Corpus of Spontaneous Japanese (CSJ), including,
1) Prosodic and morphological information of the CSJ-Core (about 44 hours) is reorganized for the study of prosodic variations. The new data is encoded as an XML document whose hierarchical structure reflects those of Japanese prosody. The most basic node of the new XML document corresponds to so-called 'accentual phrase' of the Japanese language. (Done by Kikuchi)
2) The word-origin information (i.e., Native, Sino-Japanese, Borrowing, and mixture of these) is given to the total of forty thousand short-unit-word recorded in the CSJ (by Ogura).
3) Phonetic database for the study of the variation of the velar nasal in Tokyo Japanese (by Maekawa and Hibiya).
4) RDB containing the whole word-from variations observed in the whole CSJ (7.52 million SUW.) (by Maekawa).
Based upon these data, we analyzed language variations recorded in the CSJ including,
1) Devoicing of vowels (by Maekawa ＆ Kikuchi)
2) Non-lexical lengthening of vowels (by Den)
3) Moraic nasalization of particles (by Koiso)
4) Variation of velar nasal (by Hibiya)
5) Word-form variation of the whole CSJ (by Maekawa)
6) Variation in the accentual-phrase-final rising intonation (by Maekawa ＆ Kikuchi)
7) Variation of morphological features at the end of sentence (by Ogura)
The results of these studies were presented in international and domestic conferences, and reprinted in the 252-page final report of the project.
