A Study On The Monophthong Acquisition Of Korean Students

This study focuses on the acquisition of Chinese vowels by Korean students,and uses acoustic software to select the phonetic materials of Korean students who come to China with the same Chinese level at different stages in the Chinese interlanguage dynamic tracking audio database,the acoustic parameters of the Korean students’ vowels are obtained,and the first and second formants of the vowels are extracted by using acoustic analysis software such as PRAAT and Voice Sauce.Using acoustic parameters,the vowel space diagram of Korean students at different stages is drawn.Finally,by calculating the statistical distance between the vowel acoustic parameters of each foreign student and the vowel acoustic parameters of standard Mandarin,the dynamic change of the vowel pronunciation of foreign students is revealed,and for better implementation of teaching suggestions.The results of vowel space map and acoustic distance show that the range and position of the second formant in the vowel space map are clearer,and the clustering of f 2 value is generally enhanced.This means that,after this year’s Chinese study,the Korean students in the vowels of the tongue high and low position problems have made progress.During the year of learning the target language environment,the Korean students are more clear about the forward and backward position of the tongue when they pronounce the single vowels,and the phenomenon that the forward position of the front vowel or the forward position of the back vowel has been generally improved,but the centralization of Korean students’ single vowels still exists.From the analysis of the vowel space at the beginning and the end of the school year of all the foreign students,it can be seen that the vowels of the tongue surface ü[y] and tip of Tongue-i[?] and-i[?].The articulatory position of the tongue is always unstable and accurate.It can be concluded that ü[y],-i[?] and-i[?].Before and after the tongue position is the difficulty and focus of teaching.In addition,the standard deviation of the South Korean students’ single vowel pronunciation is greater than,or even much greater than,the standard deviation of the standard Mandarin pronunciation.This means that the foreign students pronunciation of the tongue and open and close degree of instability is still very large.By comparing the standard deviation of the same vowel at the beginning and the end of the academic year,we can find that almost all the internal differences of the vowels are gradually reduced,and the pronunciation characteristics of the foreign students become more obvious.
