| In this study,the tongue-palate contact during the pronunciation of consonants in Linzhou dialect was taken as the object of study,acquisition of palatograms for physiological analysis by electropalatography scanning,making speech portrayal of Linzhou dialect more intuitive and precise.In this paper,the tongue-palate contact and the dynamic process of consonant-palatal articulation in Linzhou dialect are clearly revealed from the static and dynamic perspectives respectively,and the physiological articulation characteristics are analyzed in more detail.The thesis consists of seven chapters,which can be divided into four parts.The first chapter is an introduction,introducing the current status of research on electropalatography,co-articulation,and Linzhou dialect,the purpose and significance of the study.The experimental study of some special phonological phenomena of Linzhou dialect,such as dental vs(pre-)palatial separation and embedded l-words,can enrich the content of the study of Chinese synchronic pronunciation.The second chapter presents the experimental design and parameters.It includes the design of pronunciation word list,the selection of pronouncers,experimental equipment and recording methods,etc.This section focuses on explaining the selection of palatal position parameters,the lingual-palatal contact ratio(RCA),lingual-palatal row-by-row contact ratio(RCA1-RCA8);and contact electrode distribution index(CA,CP,CC),CA is the anteriority index,CP is the posteriority index,the CC is convergence index.In addition to explaining the calculation method of these indices,the physiological linguistic significance of these indices is also introduced.Chapters 3,4,5,and 6 are data analysis.This is the main content of the article.Firstly,we examine the tongue-palate contact in the maximum frame palatal position diagram during unitary articulation from a static perspective,and then depict the dynamic change of tongue-palate contact during unitary articulation from a dynamic perspective.This is used as a reference condition to examine the pronunciation changes of different types of consonants under different conditions of subsequent vowels,to examine the phenomenon of Linzhou dialect dental vs(pre-)palatial separation individually by group comparison,and finally to depict the process of tongue-palate dynamic changes during consonant(meta)-consonant pronunciation.Chapter 7 is the concluding remarks.To summarize the main work of the thesis,based on experimental data to illustrate the relevant conclusions of the article: consonants under different conditions of the subsequent vowel,the tongue-palate contact area changes under the influence of the vowel,and the area and area of tongue-palate contact performance is different for voiced and unvoiced consonants with the same part of articulation under the same vowel conditions;there are two kinds of performance when the Jing group word is spelled with the Tuan yin,among which when it is spelled with the lingual vowel [i],the tongue-palate contact contrast is relatively consistent with the contrast of tongue-palate contact is relatively consistent with that of the Jian group word under the same vowel condition,mainly concentrated in the hard palate area.The tongue-palate contact of the fricative [?] is not synchronized with the affricate,and the fricative is more susceptible to the influence of the tongue vowel [i] [+ front,+ high].Through this,the physiological characteristics of female voice pronunciation can be better understood.The contrast of tongue-palate contact is relatively consistent when the Jing and Jian group words are spelled with the handful of mouth calls,mainly concentrated in the posterior part of the hard palate.From the trend of dynamic changes of tongue-palate contact,the embedded l words are divided into two segments,before and after,and the mouth calls are more obvious than the open calls,and the changes of tongue-palate contact characteristics of the two segments before and after are consistent with the consonant syllable articulation.The changes of tongue-palate contact characteristics in the front and back segments are consistent with the consonant syllable articulation part,while the dynamic changes of tongue-palate contact are also affected by the combination of consonants and different vowels in the back segment when the front segment is the same;the trends of tongue-palate contact changes are similar for the air-fed and non-air-fed groups,but the air-fed feature has an impact on the tongue surface position,and the tongue-palate contact area is slightly smaller for the former;the distribution of tongue-palate contact electrodes shows an obvious transition by the changes of the front and back consonant articulation parts. |
