| According to the existing research literature materials, the study of Linfen dialect still mainly stays in descriptive research of the phonetic system and focuses on describing the whole system of the dialect. But this article is combining the traditional shangrao dialects survey with the sampling survey method of social linguistics, which focuses on researching phonetic differences of Linfen people of different ages.Combining with predecessors' research results, this article makes a dialect survey of some people (two pronouncing collaborators of 60 years old or above and another two under 30 years old)living in urban area of Yaodu District in Linfen City. According to the above survey, the thesis sorts out the phonology, sound collage rule and homophones word table of old denomination and new denomination of Linfen dialect and finds out the differences between old denomination and new denomination in initials, finals, sound collage and tone. Besides, the author personally designs " The Questionnaire on Voice Differences between Old Denomination and Young Denomination in Linfen", then, makes targeted sampling survey of the elderly (60 years old or above), the middle-aged (31 to 59) and adolescents (below 30) in streets, communities and schools in urban area of YaoDu district of Linfen City and finally conducts the statistical analysis of the collected materials and related data.Moreover, this paper briefly analyzes the reasons why old denomination and new denomination of Linfen dialect have speech differences. The one is that the dialect system's internal structure has made some self-adjustments and another is that some social and cultural factors have played a great role in this process, such as mandarin, age, gender, education level and psychological status. |
