| Phonetics teaching is the premise of teaching Chinese as a foreign language.Chinese vowels are the foundation of the Chinese phonetic system.Learning vowels well is the first step in learning the entire vowel system.Therefore,vowels acquisition is particularly important for overseas beginner Chinese learners.The learning of Chinese vowels will be affected and restricted by various factors,and it is easy to produce various errors in learning,which is the same for Chinese learners in Bangladesh.Through the communication with Bangladeshi Chinese learners,the author found that there are some problems when Bangladeshi learners speak Chinese.For example,tip vowels-i[(?)],-i [(?)] and ü [y] in vowels are the difficulties for students in learning.These vowels are unfamiliar to students because they do not exist in Bengali.Errors in pronunciation can hinder communication.If we can solve the pronunciation errors of Bangladeshi learners,we can improve the accuracy of students’ pronunciation,which can also improve their communicative level.I know in online access to the domestic researchers study about the Bangladesh Chinese learners voice data,found that now in Bangladesh Chinese acquisition of Chinese phonetic research is very little,this article will mariam agency broadcast at Bangladesh mountain degrees Confucius classroom students as the research object.The author used Praat Chinese version software to analyze the collected students’ unity-sound pronunciation files,and compared the vowel V values and formants with the standard data,so as to analyze the errors and characteristics of Bengali Chinese learners’ unity-sound acquisition from a scientific perspective.Through the analysis,The author looked up the research materials on the phonetics of Bangladeshi Chinese learners by domestic researchers on CNKI and found that there are very few researches on the phonetics of Bangladeshi Chinese learners.In this paper,students in the Confucius Classroom Broadcast in Sandu Mariam Institution,Bangladesh were selected as the research objects.The author used Praat software to analyze the recorded pronunciation files of student unit sounds.The vowel V value and formants value analyzed by the software were compared with the relevant data of standard Mandarin.To analyze the errors and characteristics of unit sound acquisition in Bengali Chinese learners from the perspective of phonological science.Through analysis,the author can intuitively find out the errors in vowels,and find that the order of students’ acquisition of lingual surface unitary sounds is i > a > u > u > o > e.In the learning of lingual tip unitary sounds,compared with middle and advanced students,junior students have a better grasp of them and give suggestions.Including the use of tape method,contrast method phonetic experiment and improve the teacher’s own professional quality.It is hoped that the author’s research can provide some help to Chinese teachers teaching in Bangladesh and Chinese learners in Bangladesh. |
