Acoustic Experiment On The Acquisition Of Monosyllabic Tones By Tibetan Students

It always been a key and difficult point that tone teaching has in second language teaching,especially for second language learners whose native tongue is non-tone language.This paper studies the acoustic characteristics and errors of the Tibetan students in the ChangSha NanFang Professional College acquire monosyllabic tones and analyzes the causes of the errors based on the second language acquisition theory,and my own teaching experience.For the research method of tone,more than half of the previous studies adopted the method of ear hearing and memorizing sounds,and analyzed the results of perceptual recording.In recent years,the research method of experimental phonetics as the phonetic research opened new doors,on the one hand,this method can carry on the quantitative data processing,more accurately than the traditional listening experiment found the problem;on the other hand,with the acoustic experiment to analyze the tone can get the more comprehensively characteristics of the length,type of tone,domain and tone pitch,and it is more comprehensive than traditional auditory perception experiments in the study of tone characteristics.So,this paper this thesis adopts the method of acoustic experiment,using the Praat speech analysis software to extract the basic frequency and duration of the Tibetan students acquire monosyllabic tones.Carry out data statistics of length,type of tone,domain and tone pitch,make tone pattern diagram,and describe the acoustic characteristics of the Tibetan students acquire monosyllabic tones.Through the comparison and analysis with the standard Beijing dialect data,we find out the errors of the Tibetan students’ acquisition of the monosyllabic tones.The papeer includes five parts.The first part is the introduction.The introduction mainly introduces why we choose this topic? The signficance of the topic,the relevant research review and the main research methods of this paper.The second part is experiment design and procedure.This part mainly explains the basic information,the choice of speech materials,and the specific experimental analysis methods and steps.The third part is the acoustic performance and error analysis of Tibetan students’ monosyllabic tone.This part mainly studies the acoustic characteristics of Tibetan students’ acquisition of the the length,type of tone,domain and tone pitch and pitch pattern of the ordinary phonetics,as well as the relative errors obtained by the comparative analysis with the acoustic characteristics of Beijing phonetics.The fourth part is about the causes of errors in Tibetan students’ acquisition of common phonetics.This part discusses the causes of errors according to the causes of interlanguage,the experimental data of acoustics and Tibetan students’ learning of Putonghua.The fifth part is Tibetan students mandarin tone teaching countermeasures.This part focuses on the causes of errors and errors,combining with their own teaching practice,puts forward relevant teaching countermeasures.The author hopes to help Tibetan students correct the pronunciation problem of "Tibetan cavity and Tibetan tone" by studying the acoustics of tone errors,and at the same time contribute to the research and teaching of Chinese tone acquisition as a second language.
