摘要
本文针对[(?)]和[(?)]、[(?)]和[(?)]的对比,重新设计声学和听辨实验以进一步探讨广州话长短元音问题,并对与[(?)]相近的[ei]、与[(?)]相近的[ou]也进行观察,以作参照。声学实验更注重对比复合元音连续频时协变之异同;听辨实验通过单向剪切和框式剪切对音节进行处理。声学和听辨实验共同证明了[(?)]和[(?)]、[(?)]和[(?)]的韵腹和韵尾极点位置都很相似,区别关键在于韵腹韵尾相对时长不同;[ei]和[(?)]、[ou]和[(?)]则韵腹极点差异较大,两者的区别在于韵腹音质不同。
This paper reports the acoustic experiment and perception test on the minimal pairs of[a：i]and[],[a：u]and[],which aim to revisit the controversial issue of long and short vowels in Cantonese.Two other diphthongs[ei]？（similar to[]） and[ou]（similar to[]） are also analyzed for comparison.The acoustic experiment mainly focuses on the continuous co-variation of formants and duration.In the perception test,the stimuli are made by adjusting the duration ratio of vowel nucleus and coda in a diphthong through unidirectional-cutting or window-cutting.It is proved that[]and[]have similar targets of nucleus and coda but vary in durational structure;while the main difference between[ei]and[]is that their nuclear vowels have different auditory qualities.Similar conclusions can be drawn from the comparison of[a：u][][ou].
