越南语静态声调的声学分析

An Analysis of the Acoustic Features of Static Tones in Vietnamese

文章运用实验语音学的基本理论和方法，使用SpeechAnalyzer软件对现代越南语的声调系统进行描写和分析，取出声学数值，算出其实际调值。实验结果显示：第一，所有声调的起点都不高，常在中央点或更低的范围；第二，除跌声之外，其它声调的基频（Fo）浮动范围比较窄。

Adopting the theory and method of Experimental Phonetics, the author uses the computer software Speech Analyzer to analyze the acoustic features of the tones in modern Vietnamese and to figure out the tone value. The results are as follows ： first, the onset of every Vietnamese tone is not high, often starting from the middle point or lower; second, except for Thanh Nga, Fo ranges of all other tones are rather narrow.
