塞辅音和声调知觉问题

STOP CONSONANTS AND TONE PERCEPTION

本文报告的两个实验以合成的汉语普通话CV音节作刺激,研究了塞辅音与声调之间在知觉上的相互作用问题。主要结果是:(1)塞辅音的发音方式影响声调的知觉,不送气音使听者在辨别声调时倾向于基频曲线起点高的声调反应;(2)音节的声调也影响对塞音发音方式的判断,在一、四声音节里,听者倾向于将塞辅音听成不送气音,在二、三声音节里,听成送气音。

Two experiments reported here were conducted with Standard ChineseCV-syllables as stimuli to investigate the interinfluence between tone andstop in consonant perception. It is shown that the manner of stop consonantarticulation, aspirated or not aspirated, has a significant effect on toneperception, that is, unaspirated stops make listeners more responsive to toneswith higher onset F? foo and that the tone of a syllble strongly affects theidentification of stop manners. When the cue of VOT is ambiguous forjudging higher onset F? of tone one and tone four, it leads, to more respo-nses of unaspirated stops.
