蒙古语卫拉特方言双音节词重音的实验语音学分析

An Experimental Phonetic Analysis on the Stress in Disyllabic words in Oirad Mongolian

蒙古语卫拉特方言实验语音学数据和分析表明,在有效控制元音分布和音节组合条件下,双音节词词重音位于词首音节;重音的主要声学相关物是音高和音质。非重读音节表现为较大的音高变化动程或相对较大的音高值,元音趋于弱化。

The experimental phonetic analysis in this paper shows that disyllabic words in Oirad Mongolian exhibit a trochaic stress pattern. In Oirad Mongolian, stress is mainly signaled by pitch and vowel quality： the stressed syllables is coupled with relatively low pitch level and full vowel quality, while the unstressed syllables with larger pitch range or higher pitch level and reduced vowel quality. Intensity and duration, which reveal primary differences in syllable structures, are not clearly related with stress. The result has been obtained in connection with the factors of vowel distribution and syllabic structure under strict control.
