本文报告的实验用时长为100—500ms的汉语普通话元音yi和ao负载的一、二声和二、三声声调连续体作刺激,用一声和二声反应曲线和平均反应百分数作指标,研究了时长和元音音色对声调识别的影响。主要结果是:(1)从一、二声和二、三声连续体得到的数据都说明,时长对声调识别有显著影响。(2)一、二声连续体的结果表明,元音音色对声调识别无显著影响;从二、三声连续体得到的结果相反,元音音色影响声调识别。文中讨论了两组数据结果的差异,并与有关的文献报告作了比较。 The experiments reported in this paper use the first and second tones of the Chinese Mandarin vowel yi and ao with the length of 100-500ms and the second and third tones of the continuous tone body for stimulation. The first and second response curves and the average response percentage are used as indices to study The effect of duration and vowel tone on tone recognition. The main results are: (1) The data from the first, second and second and third continuum show that duration has a significant effect on the tone recognition. (2) The results of one-second and two-second continuum show that the vowel tone has no significant effect on the tone identification. Contrary to the result obtained by the second and third continuum, the vowel tone affects the tone identification. The paper discusses the differences between the two data sets and compares them with the relevant literature reports.
