It is not clear, however, what the criterion for such classification was, and also whether the classification accounts for both, word-mid and word-final vowel devoicing. Thus an acoustic study was conducted to investigate the occurrence of high vowel devoicing in the above two positions and to define factors affecting it. Material was taken from the speech database collected throughout Japan between 1986 and 1989, and involves 608 respondents (304 high school students and 304 their grandparents) from 41 regions (prefectures). The data were acoustically analyzed and devoicing rates were discussed through the surrounding sounds, regional variation, and generational variation. Results revealed that the devoicing rate in dialects belonging to the so-called prominent regions of vowel devoicing rises above 60%. By observing the consonants and vowels of the following syllable, it was found out that devoicing rates differ statistically significantly in almost all regions, following the order affricate < fricative < plosive, and high vowel < non-high vowel. Regional differences obtained confirm results from the previous studies. In addition, generational difference were also found to contribute to devoicing, namely, more devoicing is used by younger generations, the tendency being especially notable in the Tohoku area. All these findings concern high vowels that are located in word-mid position and surrounded by voiceless consonants. In the word-final position, however, where high vowels are located between a voiceless consonant and a pause, devoicing rate is shown to be considerably lower irrespective of region, which brings us to the conclusion that word-final position does not condition devoicing."},{"@language":"ja","@value":"全国の母音の無声化生起にかかわる要因を探るため,1986〜1989年にかけて収集された音声資料「全国高校録音調査」の41府県の話者,老若608名の音声の音響分析を行なった。無声化生起と音環境,及び地域差との関係,世代差との関係について調べた。その結果,従来無声化が目立つとされる地域の無声化生起率はおよそ60%以上であること,ほとんどの府県において後続する子音の種類(破裂音,摩擦音,破擦音),無声化拍の後続拍の母音の種類(狭母音,非狭母音)により無声化生起率に有意差があることがわかった。また無声化の生起には地域差に加え,世代差があり,東北地方において特に世代差が著しいことが確認された。これらは語中の無声化について得られた結果であり,語末では地域にかかわらず全体として無声化生起率が非常に低く,一般的な無声化の生起環境でないことが明らかになった。"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420282801191849216","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"90468124"},{"@type":"NRID","@value":"1000090468124"},{"@type":"NRID","@value":"9000006393998"},{"@type":"NRID","@value":"9000413752215"},{"@type":"NRID","@value":"9000412189878"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/byun"}],"foaf:name":[{"@language":"ja","@value":"邊 姫京"},{"@language":"en","@value":"BYUN Hi-Gyung"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"東京大学大学院"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"13495119"},{"@type":"EISSN","@value":"21895732"},{"@type":"NDL_BIB_ID","@value":"000007423725"},{"@type":"ISSN","@value":"13495119"},{"@type":"LISSN","@value":"13495119"},{"@type":"NCID","@value":"AA11998386"}],"prism:publicationName":[{"@language":"ja","@value":"日本語の研究"},{"@language":"en","@value":"Studies in the Japanese Language"},{"@language":"ja","@value":"日本語研究"}],"dc:publisher":[{"@language":"en","@value":"The Society for Japanese Linguistics"},{"@language":"ja","@value":"日本語学会"}],"prism:publicationDate":"2007","prism:volume":"3","prism:number":"1","prism:startingPage":"33","prism:endingPage":"48"},"url":[{"@id":"http://id.ndl.go.jp/bib/8630241"},{"@id":"https://ndlsearch.ndl.go.jp/books/R000000004-I8630241"}],"availableAt":"2007","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=%E7%84%A1%E5%A3%B0%E5%8C%96%E7%94%9F%E8%B5%B7%E8%A6%81%E5%9B%A0","dc:title":"無声化生起要因"},{"@id":"https://cir.nii.ac.jp/all?q=%E9%9F%B3%E7%92%B0%E5%A2%83","dc:title":"音環境"},{"@id":"https://cir.nii.ac.jp/all?q=%E5%9C%B0%E5%9F%9F%E5%B7%AE","dc:title":"地域差"},{"@id":"https://cir.nii.ac.jp/all?q=%E4%B8%96%E4%BB%A3%E5%B7%AE","dc:title":"世代差"},{"@id":"https://cir.nii.ac.jp/all?q=%E5%85%A8%E5%9B%BD%E5%88%86%E5%B8%83","dc:title":"全国分布"},{"@id":"https://cir.nii.ac.jp/all?q=devoicing%20distribution%20map","dc:title":"devoicing distribution map"},{"@id":"https://cir.nii.ac.jp/all?q=devoicing%20rate","dc:title":"devoicing rate"},{"@id":"https://cir.nii.ac.jp/all?q=phonetic%20environment","dc:title":"phonetic environment"},{"@id":"https://cir.nii.ac.jp/all?q=regional%20differences","dc:title":"regional differences"},{"@id":"https://cir.nii.ac.jp/all?q=generational%20differences","dc:title":"generational differences"}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:2002966438"},{"@type":"NDL_SEARCH","@value":"oai:ndlsearch.ndl.go.jp:R000000004-I8630241"},{"@type":"CIA","@value":"110006318057"}]}
