Abstract：
Previous research has shown that /l/ in Spanish displays patterns of articulatory variability that are determined by a complex interaction of phonetic, phonological and dialectal factors. In this study, we report the results of an experiment using Ultrasound Tongue Imaging (UTI) that tests /l/-articulations in a dialectal cross-section of Spanish speakers. We show that lengthening of /l/ in phrase-edge contexts is accompanied by articulatory distinctions (e.g. root/dorsum retraction) for some speakers, whereas others produce lengthened realisations of /l/ in these contexts without observable differences in tongue position. We also find acoustic evidence for reduction in utterance-medial intervocalic and preconsonantal environments (duration, intensity, F1 frequency measures are discussed). However, articulatory correlates of reduction are not consistently observed across speakers in these contexts. As well as relating the results to prosodically-driven strengthening and reduction patterns, our findings are of relevance to debates about resyllabification in Spanish. Specifically, we argue that our results cannot be straightforwardly accommodated under phonological analysis assuming that word-final consonants regularly resyllabify across word boundaries prevocalically.
摘要：
以前的研究表明，西班牙语中的/l/显示发音变异性的模式，这些模式是由语音的复杂相互作用决定的，语音和方言因素。在这项研究中,我们报告了使用超声舌成像（UTI）的实验结果，该实验在西班牙语使用者的方言横截面中测试/l/-发音。我们表明，对于某些说话者，在短语边缘上下文中/l/的加长伴随着发音上的区别（例如，根/背退缩），而其他人在这些情况下产生/l/的延长实现，而舌头位置没有明显差异。我们还发现了减少话语-中间语音和前声母环境的声学证据（持续时间，强度,讨论了F1频率测量)。然而,在这些情况下，说话者之间的减少的发音相关性并不一致。除了将结果与前驱动的强化和还原模式联系起来，我们的研究结果与西班牙语中有关复制的辩论有关.具体来说,我们认为，在语音分析下，我们的结果不能被直接容纳，假设单词最终辅音定期在单词边界之间进行语音识别。
