An Experimental Phonetic Analysis Of The Uygur Students' Chinese Retroflexion And Light Tone

In recent years,Chinese second language teaching is constantly being injected with new vitality with the innovation and development of educational technology.More and more researchers are devoted to exploring new ways to promote Chinese second language acquisition.Uyghur is one of the major ethnic minorities in China,and most uygur students study Chinese at a young age.The correct pronunciation of“er-retroflexion” and light tone is an important measure of the pronunciation of Mandarin and the difficulty of Chinese second language acquisition.In order to better evaluate and guide the Chinese learning of Uyghur students,this paper tries a new way—combination of experimental phonetics and teaching.The main problems in the pronunciation of uygur students will be found through the acoustic analysis of the“er-retroflexion” and light tone,and combine with modern educational technology,we will provide corresponding methods and solutions to help Uyghur students learn Chinese better.The Chinese phonetic evaluation of “er-retroflexion” and light tone is also conducive to providing certain technical support for the personalized pronunciation guidance of uygur students in the future,and help Chinese L2 learners master the native pronunciation faster and better.Through this experiments,in retroflection,Uyghur students have major problems with pronunciation as follows:Firstly,Uygur students are poor in controlling the retroflex,and there are differences between the Male and the Female.For example,the men's retroflection are generally deficiient,but the women's retroflection are unstable,maybe excessive or scanty,or even non-rhotic;Secondly,The position and the movement of the tongue are not cooperate very well,which has an effect on the integration of the “er-retroflexion”;Thirdly,the duration of the retroflexed syllable is longer.Light tone pronunciation main problems: first of all,Uyghur students still have a long duration of pronunciation,and secondly,there are obvious errors in the tonal pattern of word after the third tone,in addition,there are also some problems with the tone pitches and the tone categories.
