A Comparative Study Of The Tone Sandhi Two Word Groups Of The Third Tone Of Chinese For Pakistani Students

In this paper,with the help of experimental phonetics,the acoustic research on the tone sandhi of the third tone continuous reading is carried out.The Pakistani students whose Chinese level is intermediate are selected.The error phenomenon and reason are mainly studied from the three aspects of the tone type,tone value and time length of the tone sandhi of the third tone continuous reading,and the corresponding countermeasures are put forward.This paper is divided into six parts.The first part is the introduction,which mainly introduces the origin,research value and research summary of this paper,and defines the research content,ideas and methods.The second part is the experimental design,establishing the experimental objects,collecting and selecting experimental materials,describing the experimental steps,and introducing the data processing methods.The third and the fourth parts are the acoustic performance and error analysis of the tone type / value before the two tone tone.The first section is the acoustic performance of the tone type / value of the single tone.The single word is used to test whether the pronunciation of Pakistani students is standard.The second section is about the acoustic performance of the tonal type / value of the two words in the third tone.In the tonal analysis part,according to the average t value,the tone is divided into five degrees,and the Pearson correlation coefficient is used as the clustering index to cluster the tonal value of the five degrees,and the objective data is used to express the acoustic performance difference between Pakistani students and Chinese students.The third section is to analyze the error phenomenon.The fifth part is the acoustic performance and error analysis of the length of time.This paper uses the method of descriptive statistics and one-way ANOVA to test the difference of the average,and makes a statistical analysis and error analysis of the pronunciation time of the double tone from three aspects: the absolute length,the time ratio of the front and back words and the time ratio of the front and back words after grouping.The sixth part is the reasons and teaching strategies.The seventh part is the conclusion,including the content summary and the innovation and deficiency of this paper.In this paper,we summarize that there are three main errors in the tone sandhi of Pakistani students: one is that the tone is not changed,the tone is not completely changed,and the overall curve is higher than that of Chinese students;the other is that the tone is not correct,the tone is not accurate;the third is that the duration is dragging The phenomenon is obvious,and each group of words has different use time and poor stability.
