Modern Chinese Dialect Library Monosyllabic Tone In The Experimental Study

This thesis studies the monosyllabic tone pattern of 40 dialects in Phonetic Database of Modern Chinese Dialects by means of acoustic experiment. We compare the effect of different F0 normalizations according to contrasts between experimental conclusion and traditional conclusion. At last we summarize some laws about tone range and tone length according to the general analysis of acoustical data we got.This thesis is mainly composed of three chapters.Chapter one introduce some academic research relate to F0 normalizations and the research methods and procedures of the experiments. The essence of F0 normalizations is how to comprehend the relation between pitch and F0 and how to simulate the psychological conversion from F0 to pitch. We introduce some related research about the relation between pitch and F0 in psychologic physics and physiology. Then we specify mathematical formula of five F0 normalizations.Chapter two list experimental results of each dialect in Phonetic Database of Modern Chinese Dialects. In pith research we gained mean of F0 and monosyllabic tone pattern, and then we discuss different experimental conclusion and the difference between experimental conclusion and traditional conclusion according as our listening perception. In tone range research we gained tone range upper limit, tone range lower limit and tone range span. Also we calculate the percent of each tone. In tone length research we gained the length sequence.Chapter three summarize three central experimental conclusion of our research. Firstly, in general the effect of logarithmic F0 normalizations is better than linear F0 normalizations. Different normalization parameters have no distinct influence to last tone value results. Secondly, tone range upper limit is the main factor that determine the span of tone range. Thirdly, the stability of each tone shape in a tone pattern determine the stability of tone length sequence chiefly. In general flexuose tone is the longest tone in a tone pattern. Aclinic tone and assurgent tone take second place. Katabatic tone is always the shortest tone.
