Abstract

In laryngeal realism (LR), laryngeal specification of stops is explained by direct maps of cues (e.g. VOT) onto privative phonological laryngeal features [voice] or [spread glottis]. Phonetic realization of the segments and speakers’ ‘control’ (e.g. the degree of intervocalic voicing and speech rate manipulation effects on VOT duration) are used as diagnostics of phonological specification. Similar to some Arabic vernacular dialects (e.g. Qatari Arabic), Khuzestani Arabic in Iran presents a case where three voiced stops /b d ɡ/ are in contrast with voiceless stops /p t k/, but two voiceless guttural plosives /tˁ q/ have no voiced homorganic counterparts. In this paper we examine the phonetic realization of voicing in these stops at word-initial and intervocalic position, as well as the effects of speech rate manipulation on VOT and closure voicing. The data came from 12 native speakers recorded in Khorramshahr, Iran. Our findings suggest an over-specified voicing system in this Arabic variety. We found that voiced /b d ɡ/ were produced with voicing lead in initial position and complete closure voicing word medially, voiceless /p t k/ had long lag VOT, while guttural /tˁ q/ had short lag VOT. Speech rate manipulation revealed that only duration of (pre)voicing and duration of aspiration increased in slower speech. Also, f0, F1, and F2 were measured at vowel onset to evaluate the glottal state in production of stops. The results support the predictions of LR that voiced stops are specified by [voice], voiceless stops are [sg], while gutturals lack underlying specification for voice.

Khuzestani阿拉伯语的喉部写实与发声对比
在喉音真实性(LR)中,喉音的停顿是通过线索(如VOT)直接映射到喉的失配音系特征[voice]或[扩张性声门]来解释的。音段的语音实现和说话人的“控制”(例如,中间发声的程度和语音速率操纵对VOT持续时间的影响)被用作语音规范的诊断。类似于一些阿拉伯方言(如卡塔尔阿拉伯语),伊朗的Khuzestani阿拉伯语出现了三个浊音顿音/b d q/与不浊音顿音/p t k/形成对比的情况,但是两个不浊音的喉音爆破音/t q/没有浊音同质对应物。在本文中,我们研究了在词头和中间位置的这些停顿发声的语音实现,以及语音速率操纵对VOT和闭合发声的影响。数据来自伊朗霍拉姆沙赫尔的12名母语人士。我们的研究结果表明,这种阿拉伯语变体中存在一种过度指定的发声系统。我们发现,浊音/b / d /是在初始位置产生发声引线,中间完全闭合发声词,不浊音/p t k/具有长滞后VOT,而喉音/t q/具有短滞后VOT。语速操纵显示,在语速较慢的情况下,只有(预)发声的持续时间和吸气的持续时间增加。此外,f0, F1和F2在元音开始时被测量,以评估在产生停顿时的声门状态。结果支持LR的预测,即浊音顿音由[voice]指定,不浊音顿音由[sg]指定,而喉音缺乏对语音的潜在规范。

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
