An Experimental Study On The Acquisition Of Chinese Diphthongs By Korean Native Speakers

Korea and China have had close contact from ancient times to the present day.There are many studies on the acquisition of Chinese pronunciation by Korean students abroad,which has laid a research foundation and provided research materials for the study of Chinese pronunciation acquisition by Chinese native speakers,however,there are few experimental phonetics studies on the acquisition of modern Chinese diphthongs.The modern Chinese pronunciation is rich in vowels,and vowels play a very important role in the acquisition of Chinese pronunciation.The pronunciation of the two vowels is dynamic,and changes dynamically with the process of pronunciation,in addition,the two vowels in the Chinese diphthongs are divided into primary and secondary vowels,therefore,the experimental study on the acquisition of Chinese diphthongs by Korean native speakers is of great significance and value.In this study,six Korean native speakers of different gender with different level of Chinese language were selected as the experimental group,and two Chinese native speakers of different gender who obtained the first grade B of Putonghua as the control group.The formant data of the experimental group and the reference group were extracted by the relevant speech experimental software,and the formant data of the two groups were normalized and relativized,the formant acoustic tongue map,formant tongue locus map and Joos type spatial acoustic tongue map were drawn.The experimental group and the reference group were compared,this paper analyzes the errors of Korean native speakers in pronouncing Chinese diphthongs due to the difference of the whole position of the tongue,the time and the degree of the turning point of the formant locus,and puts forward some teaching suggestions.The study shows that the formant of Chinese native speakers is not close to the monophthong when they pronounce the diphthongs ou[ou] and ɑo[ɑu],when Korean native speakers acquire these two Chinese diphthongs,their formant locus fluctuates greatly,and the turning point is obvious.When Korean native speakers learn Mandarin uo[uo],the starting and ending positions of the diphthongs are not high enough,and the ending positions of the diphthongs are higher and more forward than those of Chinese native speakers,the problem that the main vowels are pronounced for a shorter period of time than native Chinese speakers.When Korean native speakers at the elementary level of Chinese learn uɑ[ua],they tend to have a lower starting point of the diphthong tongue and a lower trajectory of the whole tongue,a condition in which the main vowel is pronounced for a shorter period than the native Chinese speaker.
