A RESEARCH ON THE VARIATION OF VOICED VELAR STOPS AND VELAR NASALS IN LOOCHOO, KYUSHU AND SHIKOKU DIALCTS

1999年，在高知市的奥托约进行了实地研究。作为研究的结果，明确了以下事实。/g/是发声的韵母，停在单词的起始位置，并在声间位置预鼻化。这在老一辈人中比在年轻一代中更常见。YIG告密者发音为不含鼻音成分的浊膜停顿。还在宫古群岛的一个岛屿--伊拉武岛进行了实地研究。在伊拉布方言和中内方言中，声门塞音对应于东京方言的浊音和无声塞音。2000年，DAT在伊拉布和中内地区进行了视频拍摄和记录。在与那国岛也进行了实地工作。Yonaguni方言是已知的唯一一种在发音间位置有膜鼻辅音的方言。由于鼻音的时长不稳定，有可能将其理解为非音节辅音或音节鼻辅音，因此必须了解其音节结构，才能对其进行音素解读。基开方言中存在声间膜鼻，而在据报道有声间膜鼻的Makurazaki方言中，大多数浊膜辅音是停顿的。2002年，制作了Irabu和Nakachi音的CD。

In 1999, field research was carried out in Otoyo, Kochi. As a result of the research, the following facts were made clear. The / g / is voiced velar stop at word initial position, and is pre-nasalized at the inter-vocalic positions. This is more common in the older generation than in the younger generation. Youg informants pronounce voiced velar stop without nasal element. A field research was made also in Irabu island, one of the islands of Miyako archipelago. In Irabu and Nakachi dialect, glottal stop coresponds to voiced and voiceless velar stops of Tokyo dialect.In 2000, video shooting and recording by DAT was done in Irabu and Nakachi area. And field work was carried out also in Yonaguni island. Yonaguni dialect is known as only dialct to have velar nasal consonant in inter-vocalic position. It is necessary to know the syllable structure to make phonemic interpretation of the velar nasal because the duration of velar nasal is not stable and it is possible to interpret it either as a non-syllabic consonant or a syllabic nasal consonant.In 2001, field work was made in Kikai dialect and Makurazaki dialect. It was confirmed that there is inter-vocalic velar nasal in Kikai dialect, while in Makurazaki, which was reported as a dialect to have inter-vocalic velar nasal, most of the voiced velar consonants are stops.In 2002, CD of the Irabu and Nakachi sounds was made.
