Presently there is no consensus regarding the interpretation and analysis of the stress system of Moroccan Arabic. This paper tests whether the acoustic realisation of syllables support one widely adopted interpretation of lexical stress, according to which stress is either penultimate or final depending on syllable weight. The experiment reports on word-initial syllables that differ in presumed stress status. Target words were embedded in a carrier sentence within a scripted mock dialogue to ensure that the measurements reflect lexical stress rather than phrase-level prominence. Results from all four acoustic parameters tested (f0, duration, Centre of Gravity and vowel quality) showed that there were no differences as a function of presumed stress status, thus failing to support an interpretation according to which stressed syllables are acoustically differentiated. We consider the results in relation to previous claims and observations, and conclude that the absence of acoustic correlates of presumed stress is compatible with the view that Moroccan Arabic lacks lexical stress.

摩洛哥阿拉伯语词汇重音的声学相关性

目前对摩洛哥阿拉伯语的重音系统的解释和分析还没有达成共识。本文测试音节的声学实现是否支持一种广泛采用的词汇重音解释,根据该解释,重音是倒数第二个或最后一个,取决于音节的重量。该实验报告了假定重音状态不同的词首音节。目标词嵌入脚本模拟对话中的载体句子中,以确保测量反映词汇压力而不是短语级别的突出性。测试的所有四个声学参数(f0、持续时间、重心和元音质量)的结果表明,作为假定的压力状态的函数,没有差异,因此不支持重读音节在声学上区分的解释。我们考虑了与先前的主张和观察相关的结果,并得出结论,假定重音的声学相关性的缺失与摩洛哥阿拉伯语缺乏词汇重音的观点是一致的。
