In recent years,as trade between China and South Korea has become more frequent,south Korean companies have moved into China.As the increasing number of Korean-invested enterprises,the demand for learning Chinese is also increasing.Meanwhile,the TSC(Test of spoken Chinese)was created to test the Chinese proficiency of Korean employees.In the practice of teaching Chinese for one year in xi ’an Samsung semiconductor limited liability company,we found that TSC learners’ phonetic problems in TSC courses were a big problem in the learning process,especially the erasing of consonants,which became the common phonetic errors of TSC learners.At present,there are few acoustic researches on Korean Chinese learners’ phonetic errors,and few people pay attention to acoustic experimental researches on TSC learners’ phonetic errors.In this paper,the acoustic analysis method of traditional consonant experimental research is adopted to classify TSC learners into three levels: primary,intermediate and advanced.The analysis of fricative f[f] was mainly carried out from three aspects:disorderly grain characteristics,fricative length and the energy distribution.In the analysis of h[x],the relationship between the energy peaks of the fricative h[x],the initial lower limit frequency and the energy peak of the trailing vowel is mainly analyzed.Analysis of fricative r [?],mainly analyzed from three aspects,namely the voiced dash frequency value,initials the value of the first and the second formant frequency,the third formant and the relationship between the final third formant;Analysis of fricative s [s]、x [?]、sh[?] acoustic features,using quantitative analysis method from the cut-off frequency comparing with native speakers.In this paper,the comparative analysis method is adopted to compare Chinese and Korean consonant tables.Meanwhile,the problems in TSC teaching are comprehensively analyzed to analyze the fricative errors of TSC learners.Based on the analysis of the phenomenon of TSC learners’ fricative errors,it can be seen that TSC learners’ pronunciation in different stages has both generality and individuality,so it is very necessary to carry out concentrated phonetic teaching in the primary stage,and appropriate measures should be taken to solve the problem of learners’ errors in different stages.In order to improve the accuracy of TSC learners’ frictional pronunciation,this paper puts forward some teaching suggestions from the aspects of teaching,teachers and students themselves. |
