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语言系统的组成部分。但在今天，它的功能正在从语言系统向文体转变，并受到各种情境因素的制约。个体内部确实存在许多代码；方言代码、共同语代码等。本研究旨在阐明语言使用的全貌，特别关注方言语码的频率，以及方言语码与标准日语语码之间的语码转换。考虑到对话者、情境和话题的差异。在关西地区的百货店、超级市场、小型民营商店等不同类型的零售企业，收集了在服务过程中自发发言的调查结果。进行了转录，并提供了服务遇到的数据库。电子版本也可用于快速搜索。分析了每种零售业务的实际语言使用情况，并对这些类型进行了比较。许多报告声称，传统的方言形式在年轻一代中正在消失。然而，事实是方言形式并没有取代标准日语形式；新的地方语言风格（即新方言）由此产生。通过这种方式，分析了方言代码变化的机制，重点分析了标准日语、东京方言和关西方言对方言代码的干扰程度。

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.
