Experimental Phonetics Of Japanese Special Phonemes

Japanese learners in China will generate the phenomenon of nasal disorder in the process of learning Japanese,they may have difficulty in studying dial tone in Japanese.The reasons are that the dial tone is a special kind of phoneme,and it can be divided into[m][n]?[?]?[N]and nasal vowels according to the following vowels and constants.So this thesis regards the phonetic teaching as the starting point,and uses the method of experimental phonetics.For the thesis,the research objects are the college students—freshman,sophomore,junior students and the teachers who speak Japanese as their native language;the experimental phonetics software the thesis uses is Praat and statistical software called SPSS to study the question of the direct influence of resonance Peak in the dial tone FI,F2,F3,when a word of dial tone "e+/N/" followed by different vowels and consonants;the author makes a comparative analysis between the condition of segment dial tone about the college students mentioned above and the native speakers.Through the experimental study and analysis,the author finds that the reasons of the errors roughly exist are following:the influence of the learning time,the abstraction of nasal teaching and the negative transfer of the native language.The mastery degree varies for the learners in different levels,that's the Japanese learners from three grades all have errors in some different degrees during the process of pronouncing the dial tone,among them,the words of dial tone followed by affricates,such as Tongue[ts](???,?)and coronal[d3](????)are the worst ones that are mastered by them.When pronouncing,the position of the soft palate and the apex of Japanese learners' are higher than the native speakers.Therefore,Japanese teacher and learners should pay more attention to these words in the process of teaching the segment dial tone and learning Japanese.
