| Base on the investigation on acquisition of the tones of Pakistan students who is studyingChinese in China and the principle of experimental phonetics and the Mini speech labsoftware developed by Nankai University, the thesis analysis the study of students in twodifferent stages. It is mainly on tone frequency value, standard deviation, T value and otheraspects. And finally it puts forward some teaching strategies to the bias.The way of the study is mainly on sampling investigation. We pick up8students,4ofthem have never leaned Chinese and the rest have learned Chinese for almost half of a year.After we get their tone pronunciation samples, we handle these data with the Mini speech Labsoftware and get the average duration, frequency, T value and standard deviation etc. Then weanalysis of the tone and pitch according to the data’s features.The thesis is divided into5parts. The first part is the introduction, it’s mainly introducesthe reason of choosing the Topic and some contents on relevant research, methods and resultsof recent years. The second part is about analysis of tone of primary stage of Pakistan students.The third part is about the contrast analysis on two stage Pakistan students’s bias tone, itincludes both diachronic and synchronic comparison. The diachronic comparison is about thetone type and tone value of students whose study time is different. Synchronic comparison isthe comparison with Beijing dialect. The fourth part is mainly on the reasons of the bias andcountermeasures for the bias. The last part is the conclusion of the experimental research. |
