Pronunciation Study On Zh[(?)], Ch[(?)], Sh[(?)] Of Vietnamese Students

With the development of economic and cultural exchanges between China and Vietnam,Vietnamese Chinese teaching is also developing and the development trend of "Chinese fever" in Vietnam is becoming more and more obvious.The study of Vietnamese teaching has also developed rapidly with the development of teaching scale,among which the research on voice bias of Vietnamese students is also increasing.Based on this reality,we can find that the study of Vietnamese students' phonetic problems has gradually developed into a hot topic in the teaching of Chinese as a foreign language.But also because it is a new hot spot,the literature of speech error research is still relatively small,the existing research content to tone bias research and voice problems of the overall summary of the main focus on the overall error analysis,Lack of specific and in-depth analysis of the description,the lack of targeted voice teaching methods and strategies.This article is different from the existing research,the author first consulted the relevant existing research results,found that Vietnamese students do have some obvious problems in Chinese pronunciation and then the author begin to learn more about it by the usual teaching observation and interviews and found that Vietnamese Chinese learners do have obvious problems in zh [t?],ch [t?'],sh[?].In order to carry out further scientific research to verify the author's hypothesis,the author begin to use field voice survey.The focus of the study on the initial consonant voice error,according to the voice survey and statistical data,verify the zh [t?],ch [t?'],sh [?] problem is indeed Vietnamese Learners' typical speech errors,whether in a single syllable,word or discourse.Vietnamese Chinese learners are the most typical and prominent vowel voice errors are concentrated in zh [t?],ch [t?'],sh [?].Vietnamese Chinese learners show the type of error is more consistent in zh [t?],ch [t?'],sh [?],they usually use the pronunciation of z [ts],c[ts' ],s [s] to replace zh [t?],ch [t?'],sh [?].On the basis of the theory of error analysis andcomparative analysis,the author analyzes the causes of the errors of the three Chinese characters zh[t?],ch [t?'],sh [?] of the Chinese learners in Vietnam.Finally,the author combines the results of speech investigation,the existing literature research results and her own practical experience to think up with some teaching principles and methods in teaching.The author believe that in the process of teaching,teachers should adhere to the student-centered,teacher-led principle;comparative analysis and so on.In the more phonetic teaching methods,teachers should pay more attention to syllable teaching,focusing on language teaching;pay attention to improve the ability to listen,to develop language sense of sound and so on.
