摘要

阿拉伯语中的重音(冠音的对比发音)从一个重音辅音传播到相邻的音节。先前的研究表明,除了改变相邻片段的频谱特征外,重音还可能影响无声塞音的发音起始时间,因为阿拉伯语方言中的重音塞音的VOT比其同源词短得多。没有研究调查强调共同发音是否能缩短强调环境中产生的平抑音的VOT。本研究使用来自16名卡塔尔阿拉伯语使用者的生产数据,调查了音节声母/t/中VOT的变化,这些人阅读的非单词音节的声母为平抑和重音/ṭ/ 与另一个普通辅音或重音辅音相邻。结果表明,重音扩展是一个只影响音段频谱特征的梯度过程,导致元音共振峰和词尾频谱重心的变化。然而,在重音音节中,纯/t/的长滞后VOT并没有缩短。研究结果表明,卡塔尔阿拉伯语中无声强调停顿中较短的VOT并不是发音的机械后果,而是在普通和强调停顿中保持长滞后和短滞后VOT对比的语音要求。

Effect of emphasis spread on VOT in coronal stops in Qatari Arabic
Emphasis (contrastive pharyngealization of coronals) in Arabic spreads from an emphatic consonant to neighboring segments. Previous research suggests that in addition to changing spectral characteristics of adjacent segments, emphasis might affect voice onset time (VOT) of voiceless stops because emphatic stops in Arabic dialects have considerably shorter VOT than their plain cognates. No study investigated whether emphatic co-articulation could shorten VOT in plain stops produced in emphatic environment. The present study investigates changes in VOT in syllable-initial /t/ using production data from sixteen speakers of Qatari Arabic, who read non-word syllables with initial plain and emphatic stops /t/ and /ṭ/ adjacent to another plain or emphatic consonant. The results show that emphasis spread is a gradient process that affects only spectral characteristics of segments, causing changes in vowel formants and spectral centre of gravity of stops. Long-lag VOT in plain /t/, however, was not shortened in emphatic syllables. The findings suggest that shorter VOT in voiceless emphatic stops in Qatari Arabic is not a mechanical aftermath of pharyngealization but, rather, a phonological requirement to maintain contrast between long-lag and short-lag VOT in plain and emphatic stops.

期刊介绍: The Journal of the International Phonetic Association (JIPA) is a forum for work in the fields of phonetic theory and description. As well as including papers on laboratory phonetics/phonology and related topics, the journal encourages submissions on practical applications of phonetics to areas such as phonetics teaching and speech therapy, as well as the analysis of speech phenomena in relation to computer speech processing. It is especially concerned with the theory behind the International Phonetic Alphabet and discussions of the use of symbols for illustrating the phonetic structures of a wide variety of languages. JIPA now publishes online audio files to supplement written articles Published for the International Phonetic Association
