Experimental Study On Acquisitions Of Mandarin’s Fricative And Affricate Of Northeast Thailand Primary School Students

With the close cooperation between China and Thailand in the fields of economy,culture and trade,the number of people learning Mandarin in Thailand has increased year by year.As the material representation of language,the speech is the most important thing to learn a language.Both Mandarin and Thai belong to the Sino-Tibetan language family.There are some common characteristics in the phonetic system,which is conducive to Thai students learning Chinese.However,there are also great differences between that two languages,which often lead the Thai students having some errors in learning Mandarin and having difficulties in pronunciation.In view of this,this thesis uses the method of experimental phonetics to analyze the learning of Mandarin’s fricative and affricate in Northeast Thailand primary school students,and compares with Chinese native speakers’ fricative and affricate voices.Finding out the difficulties and errors of speaking Mandarin’s fricative and affricate in Northeast Thailand primary school students.At the same time,combined with the perception experiment,the thesis verifies that perception error is one of the reasons leading to the errors in learning Mandarin.Then it classifies difficulties and attempts to explore why that occurs.Finally,based on this,it proposes corresponding teaching suggestions.The full text is divided into six parts:The first part is the introduction,which mainly expounds on the reason of the topic,the significance of the research,the related theoretical basis and the research status.This part also introduces the main research contents and methodologies and a brief introduction to both Mandarin and Thai language consonants system.The second part based on the two-syllable words,this part carries out the acoustic experiments of Mandarin fricative,which were spoken by 24 Northeast Thai primary school students in the second,fourth and sixth grades,focusing on the center of gravity,dispersion,and finds out the pattern of Northeast Thai students’ fricative.At the same time,compares the data and pattern of the fricative of Chinese and Thai speakers,then finds out the fricative acquisition characteristics of Northeast Thai primary school students.The third part,based on the two-syllable words,carries out the acoustic experiments of Mandarin fricative which were spoken by 24 Northeast Thai primary school students in the second,fourth and sixth grades,focusing on the GAP,DOF,center of gravity and dispersion.Using the data of GAP and DOF,it presents a pattern of Northeast Thai students’ affricate duration;using the data of center of gravity and dispersion,it shows a pattern of Northeast Thai students’ affricate friction;then using the ratio of GAP and DOF,the center of gravity and dispersion,it gets the Duration Index,the Friction Index and the pattern of the Northeast Thai students’ affricate.Next,it compares the data and pattern of the affricate duration,affricate friction,affricate of Chinese and Thai speakers,then finds out the affricate acquisition characteristics of Northeast Thai primary school students.The fourth part applies the perception experiment and uses the experimental method of perceptual recognition to statistically analyze the distribution of the perceptual errors of the Mandarin’s fricative and affricate of the primary school students in Northeast Thailand.The study finds out the influence of perception on the acquisitions of Mandarin’s fricative and affricate of primary school students in Northeast Thailand.Discovered that perceptual error is one of the reasons why the primary school students in Northeast Thailand have errors when they learn Mandarin fricative and affricate.The fifth part synthesizes the conclusions of the second,third and fourth parts to analyze the pronunciation difficulties and the causes of them when Northeast Thai primary school students have when studying Mandarin’s fricative and affricate.Finally,it proposes relevant teaching suggestions on the difficulties.The sixth part is the conclusion.
