A study on the change in dialect-code : evidence from ‘Corpus of Japanese Dialects'

方言被认为是特定社会中的语言系统。然而，今天，它的功能正在从语言系统向文体转变，这受到各种情景因素的制约。方言代码、日语通用代码等等。本研究旨在阐明语言使用的全貌，特别是方言代码的使用频率，以及方言代码和标准日语代码之间的代码转换。在此基础上，对关西地区百货公司、超市、民营小商店等不同类型的零售企业的服务接触中的自发话语进行了调查。制作了记录，并提供了服务中的数据库。电子版本也可用于快速搜索。分析了每种类型的零售业务的实际语言使用情况，并进行了比较。许多报告声称，在年轻一代的说话者中，传统的方言形式正在消失。然而，事实是，方言形式并没有取代标准的日语形式，而是新的当地语言风格(即新方言)的出现。在此基础上，重点分析了标准日语、东京方言和关西方言的干扰程度，找出了方言代码变化的机制。

Dialect was thought to comprise linguistic system in a given society. Today, however, its function is changing from linguistic system into style, which is constrained by various situational factors. A number of codes do exist within an individual ; dialect-code, common-Japanese-code and so on.This study aimed to clarify a whole picture of language use with a special reference to the frequency of dialect-code, and to that of code-switching between dialect-code and standard-Japanese-code. The differences of interlocutors, situations, and topics were taken into consideration.A survey was conducted to collect spontaneous speech in service encounters at different types of retail business : department stores, supermarket, and small privately run shops in Kansai area. Transcriptions were made, and database in service encounters become available. Electric version is also available for a quick search.Actual language use was analysed in each type of retail business, and comparisons between those types were made. Many reports claim that traditional dialectal forms are disappearing amongst younger generation speakers. However, the fact is that dialectal forms are not gone in place of standard Japanese forms; new local speech style (i.e.neo-dialect) emerges as a result. In this way, analyses were made to find the mechanism of change in dialect-code, focusing on the extent of the interference from standard Japanese, Tokyo dialect and Kansai dialect.
