摘　　要：基于《彝语声学参数数据库》,本文讨论了彝语男发音人的两对松-紧喉元音/u/、/y/和/ur/、/yr/在CV音节中的元音时长、音强、音高和共振峰。Based on the Unified Yi Acoustic Parameter Database, this paper examines the duration, intensity, pitch and formants of two pairs of lax-tense vowels （/u/-/ur/,/y/-/yr/） in CV syllables of the Yi language, spoken by a male speaker. Conclusions are as follows： First, duration of tense vowels in word-final open syllables is shorter than that of their counterpart, whereas for non-word- final syllables, the SD （Standard Deviation） of duration of tense vowels is bigger than that of lax vowels. As for intensity, the vowels show no significant differences. Compared with/u/and/y/,/ur/ and/yr/are opener and more backward, and/ur/has much bigger SD ofF2 than that of/yr/. Second, for syllables with/u/and/y/, Tone 55 is realized as Tone 45. Tone 44 and 33 of syllables with lax vowels are level tones, while those of syllables with tense vowels act like H-L tones to some extent. Third, in terms ofF1 pattern, Tone 33 of syllables with/u/and/y/is the smallest and Tone 55 is the biggest, whereas for syllables with/ur/and/yr/, Tone 44 is small in F1 and Tone 33 is big. In terms ofF2 pattern, Tone 21 of syllables with/u/is the smallest, while Tone 55 of syllables with/y/is the smallest. Tone 44 of syllables with/ur/is smaller in F2 than Tone 33, whereas Tone 44 of syllables with/yr/is bigger than Tone 33.
