The Experimental Phonetics Study On The Consonants Of The Ri Zhao Dialect

This article mainly use the method of experimental phonetics to research the places of articulation and the manners of the articulation of Rizhao dialect. We use the palatographic and linguagraphic datas to research the articulation of Rizhao dialect and compare it with the traditional research.We find that most of the articulations of the consonants are the same, but the place of articulation of stop [t] and nasal [n] have a big difference with the research of the forefather’s. [t] and [n] are the laminal-postalvelar, compare with the research of the forefater, the position of the two sounds are far back.Ther reason may be the different kind of the method,Comapare with the traditional method, the method of experimental phonetics is more Objective.[l] is an apicol-postalveolar,but it also has the variant. The place of the artivulations of the affricate consonants and the fricative consonants are almost the same with the research of the forefathers. The place of the articulations of [tθ] 、 [θ] are the apical-dental, [t?]、[?] are the apical-alveolar, [? ]、[?] are the laminal-alvelar, [t?]、[?]are the laminal-postalvelar. On the basis of the research we find that almost all the consonants have the variants,and there is sexual difference, the male’s articulation are far more back than the the female’s,especially for the consonants of [?]、[?]、[?].Beside the research of the place of the articulation, we also research the acoustic characteristics which include the description of spectrogram 、the measurements of duration 、 the infection of the vowel onset and the transition.The place of the articulation and the acoustic characteristics are interacted on each other. Whether it is an unaspirated consonant or not 、 different kinds method of articulation and the strength of the airflow have a big influence of the ambiguity of the spectrogram and the duration of the consonant.The aspairated consonants have a longer duration than the unaspairated consonant. The contact area of the tongue and the palate also have a big influence on them.Comapare the unaspairated laminal consonant with the aspairate apicol consonant, the unaspairated one is fuzzier. The contact area of the tongue and the palate affect the air velocity, then it affect the duration of theconsonant.Through the statistical analysis of the duration we find that there is no significant difference in the race of the vowels and the sexual difference. In the research of the infection of the vowel onset, we find that the tongue postion of the consonant, the size of cavum pharynges have a big infection on the vowel onset F1;the tongue postion of the consonant has a big infection onf the vowel onset F2,compared with the apical, the laminal one has a higher value.
