摘要

节奏度量可以检测目标样语音节奏的第二语言发展,但从学习者语音中的度量对结果的解释是有问题的,因为度量与基础语音特征的映射是间接的。我们研究了第一语言(L1)阿拉伯语/第二语言(L2)英语的语音节奏,这两种语言在有助于感知节奏的关键特性上有所不同:非重音元音还原和音节结构。我们的生产数据是使用额外的测量来解释的,重音和非重音元音以及辅音簇的实现,以及标准的节奏度量;这种组合有助于消除对度量结果的竞争性解释的歧义。研究结果证实了使用多种节奏指标来研究二语语音节奏的重要性,并证明了简单的额外测量如何指导对其结果的解释。在这项研究中,指标结果表明,与母语为阿拉伯语和英语的人相比,二语使用者的语音,无论他们在英国居住的时间长短,都表现出较低的声音持续变异性。然而,对母语和非母语群体元音减少程度的仔细检查证实,没有一个单一的指标能够捕捉到所观察到的L2节奏模式的复杂性质。建议未来的二语研究不要仅仅根据节奏指标的结果就二语语音中元音减少和辅音簇实现的程度得出确切的结论。

Methods for investigation of L2 speech rhythm: Insights from the production of English speech rhythm by L2 Arabic learners
Rhythm metrics can detect second language development of target-like speech rhythm but interpretation of the results from metrics in learners’ speech is problematic because the mapping of metrics to underpinning phonological features is indirect. We investigate speech rhythm in first language (L1) Arabic / second language (L2) English, which differ in key properties contributing to the percept of rhythm: unstressed vowel reduction and syllable structure. Our production data are interpreted using additional measures, of stressed and unstressed vowels and of consonant cluster realization, alongside standard rhythm metrics; this combination facilitates disambiguation of competing interpretations of the metric results. The findings confirm the importance of using multiple rhythm metrics to study L2 speech rhythm and demonstrate how simple additional measures can guide interpretation of their results. In this study the metrics results showed that the speech produced by the L2 speakers, regardless of their length of residence in the UK, exhibited lower vocalic durational variability than the speech produced by the native Arabic and English speakers. However, closer inspection of the degree of vowel reduction by the native and nonnative groups confirms that no single metric captures the complex nature of the observed L2 rhythm patterns. Future L2 studies are advised not to draw firm conclusions about the degree of vowel reduction and consonant cluster realization in L2 speech based solely on the results of the rhythm metrics.

期刊介绍: Second Language Research is a high quality international peer reviewed journal, currently ranked in the top 20 journals in its field by Thomson Scientific (formerly ISI). SLR publishes theoretical and experimental papers concerned with second language acquisition and second language performance, and adheres to a rigorous double-blind reviewing policy in which the identity of both the reviewer and author are always concealed from both parties.
