Sichuan Qianwei Dialect Morphological Phonology Research

This dissertation focuses on the research of the Mropho-phonology phenomena of Qianwei dialect in Sichuan province,combines the traditional grammatical description with the acoustic phonetic research,and analyzes the Reduplication morphology and The suffix "Er" morphology of Qianwei dialect from the perspectives of general description and experimental analysis and investigates the phonetic features under the grammatical form.There are four Chapters in the dissertation.The questions discussed include the constitution form of the reduplication and the suffix "Er" word?the grammatical function and the semantic characteristics,the prosodic features of the Reduplication morphology,acoustic space?coarticulation and the prosodic features of The suffix "Er" morphology.The1^stt Chapter is the introduction,which mainly introduces the object of study?related research overview and the experimental plan.the main parts of the dissertation are the 2ⁿdd Chapter and the 3^rd Chapter,the Reduplication and the suffix "Er" are analyzed by general analysis and acoustic experiment.The 4^th Chapter is the conclusion,which summarizes the foregoing and puts forward the deficiency and prospect of this dissertation.Through research and discussion,this dissertation argues that grammatical morphology will have a certain impact on the phonetic features,and the main results are as follows:The Reduplication morphological parts:1.tone pitch of the overlapped syllables change significantly and are mainly in the 3 and4 zones,tone range of all syllables are very uniform and basically located in the middle part.Level tone is in the majority,Falling tone and rising tone mostly drop or rise by 1 degree,with very small range.2.tone contour has a certain effect on the duration of the reduplication.In most cases,The duration of level tone and rising tone is relatively long,while the duration of falling tone is relatively short.3.When the overlapped syllables are level tone,rising tone and falling tone,the intensity pattern of the overlapped syllables is generally the latter strong type.When the overlapped syllables are falling-rising tone and entering tone,the intensity pattern of the overlapped syllables is generally the former strong pattern.The suffix "Er" morphological parts:1.There is a significant difference in the central tendency of vowel formant between the suffix "Er" and the root "Er" .F2 and F3 of the suffix "Er" are both larger than the root "Er" ,and F2 and F3 are acoustic parameters with significant classification significance.The intergenerational change of the suffix "Er" is obvious while the gender difference is small.2.There is a significant difference in the discrete tendency of vowel format between the suffix "Er" and the root "Er" .The dispersion degree of the suffix "Er" is smaller than that of the root "Er" ,and F3 is a acoustic parameters with significant classification significance.The gender difference of the suffix "Er" is significant,but the age difference is small.The dispersion degree and the variability of the suffix "Er" words of the overlapping stem are large.3.There is a difference between the pitch performance of the suffix "Er" and the root "Er" .when the front connection is level tone?falling-rising tone?falling tone and entering tone,the tone contour remains unchanged and the tone range rises,the tone value is 43.When the front connection is rising tone,the tone contour flattens and the tone range rises,the tone value is 44.The overlapping stem and the simple stem have an effect on the pitch of the suffix "Er" ,and the inflection of the final is different from the whole situation.The tone value change of the suffix "Er" is different from the overall situation.4.The duration pattern of the suffix "Er" is T2-er>T1-er>T3-er>T7-er>T5-er.The overlapping stem and the simple stem have an effect on the duration of the suffix "Er" ,The duration performance is different from the overall situation and the gender difference and age difference are bigger.5.In coarticulation with the segment,F1 of the suffix "Er" decreases,F2 increases and part of F3 increases.The retroflex color of the suffix "Er" is weaker than the root "Er" and when the nasals are in front,The suffix "Er" is nasalized in hearing.
