An Experimental Study On The Two-character Tone Sandhi Of Dachangshan Island Dialect In Changhai County

The dialect of Dachangshan Island in Changhai County,which belongs to Yanwei small slice of the Jiao Liao Mandarin dialect.It is a three-tone dialect.The author was fortunate enough to participate in the "Chinese dialect investigation in Liaoning Province,China language Resource Conservation Project",which conducted by my tutor.When combing the words of Dachangshan Island,I founded that the single and double tone in Dachangshan Island's dialect had distinct characteristics,so I consulted the materials and proposed further research.In the field recording,5 speakers of the original language preservation project were selected,and 3 other Dachangshan Island speakers were selected,a total of 4 men and 4 women.The Dachangshan Island phonetic questionnaire,the single-word questionnaire and the double-word questionnaire were recorded.One copy,and then use the relevant methods of experimental phonetics to select and calculate,and then summarize the single and double tone patterns of the Dachangshan Island dialect.On the basis of single-character tones,further explore the transposed mode of the double-character combination of Dachangshan Island,summarize the tonal characteristics of the double-character tones,and analyze the arch configuration and transliteration tone theory using the theory of "folding and grinding" to seek Liaoning The relevant follow-up studies of the regional Jiaoliao mandarin provide reference.In addition to the introduction and conclusion,the article is divided into four chapters:The first chapter introduces the acquisition process and experimental methods of real dialect investigation.The first section introduces the selection of the speaker in turn,the design of the recording survey table and the recording process.The second section specifically explains the operation method of this experiment: first filter out the data with obvious noise on the hearing sense,then use praat voice software to segment and mark it,manually adjust the abnormal fundamental frequency point,and finally run the script program to extract Single word and double word fundamental frequency value to obtain its pitch data.The second chapter introduces the phonetic system of the Dachangshan Island dialect.Dachangshan Island has a total of 22 initials,which have both tongue tip midtone[n] and tongue facial sound [?];37 finals,including 8 simple finals and 28 compund finals;there are only three types of tones,ping tone,shang tone and qu tone.Ping tone does not distinguish between yin and yang,and it belongs to the typical three-tone dialect.The third chapter uses the acoustic experiment method to sort out the single-tone tone pattern of Dachangshan Island.According to the differentiation characteristics,the basic frequency curve of single-word tone is classified respectively,and thecorresponding five-degree tone value is obtained uniformly.Finally,the T value of the 8speakers is obtained by the average method to obtain the single-word tone of Dachangshan Island Pattern: The dialect of Dachangshan Island belongs to the three-tone dialect,and there is no yin and yang differentiation in ping tone,its tone pitch is[52],shang tone is [213],and there are two tone adjustment modes,one type is a curve that rises first and then descends or parallel first and then descends,recorded as [442],and the other type is straight down,recorded as [42].The fourth chapter,on the basis of the single-character tonal pattern,uses the acoustic experiment method to explore the double-character tonal pattern and the transposed pattern of the Dachangshan Island dialect.First,by extracting the fundamental frequency data of the front and back words as the F0 fundamental frequency curve chart,summing up and summarizing the trend characteristics of the 8-bit speaker's curve;secondly,performing normalization processing to obtain the corresponding five-degree tone value and exploring a few bits The tone-sharing laws common to speakers,summed up 10 types of tone-sharing patterns in Dachangshan Island.The experimental results show that although the Dachangshan Island dialect does not distinguish between yin and yang in single-word tones,it still retains the phenomenon of clear and turbid tone in double-word combinations.The distinction between yin and yang is the result of merging again after differentiation.Finally,using the theory of "degree of grinding",further analysis of the arch configuration principle of the combination of the double character of Dachangshan Island before and after the tone change.Experiments have shown that Dachangshan Island can be adjusted by grinding and bending degree to achieve labor-saving language economic benefits.
