Acoustic Experimental Study On The Acquisition Of "Yi" And "Bu" By Foreign Students With HSK Level 4 As An Example

This paper investigates the tonal characteristics and tonal errors of "Yi" and "Bu" of foreign students from different countries,and makes an experimental analysis according to their tonal pronunciation,and finally puts forward corresponding teaching suggestions on the performance of tonal.Mistakes and actual learning.We randomly selected 30 students from the Chinese conversation class of international students in the School of International Education of Southwestern University of Finance and Economics to conduct a questionnaire survey on the acquisition of "Yi" and "Bu" tones,and finally collected 29 valid questionnaires.Through the analysis of the questionnaire results,it is found that there are great problems in the acquisition of "Yi" and "Bu" tones.Therefore,7foreign students from different mother tongue countries were selected as the experimental objects of this paper.Praat speech analysis software was used to analyze and describe the quintic spectrum of "Yi" and "Bu" original consonants of 7 subjects.The comparative analysis was carried out according to the relevant standards of Mandarin Chinese.This paper tries to find out the harmony acquisition errors of "Yi" and "Bu".The thesis is divided into six parts.The first part introduces the writing reason,the significance of the topic and the relevant research review.In the second part,the experimental objects and pronunciation materials are defined,and the experimental purpose,experimental process and experimental methods are introduced.The third and fourth parts mainly analyze the acoustic performance of "Yi" and "Bu" spoken by foreign students from different countries.In "Yi" and "Bu",the harmonic "Bu" modulated by "Yi",the change of suffix "Yi" and "Bu" to "Yi" and "Bu",the four types of light tone "Yi/Bu + flat" and "Yi/Bu+ flat" and "Yi" "Bu" are analyzed and discussed one by one,to explore the performance of the experiment in different language structure pronunciation.The fifth part,according to the mistakes of foreign students,combined with the actual teaching situation of the corresponding teaching suggestions;The sixth part is the conclusion,including the overall conclusion and the shortcomings of this paper.
