摘要本研究描述了在奈梅亨西班牙语语料库中，元音间/s/的弱化现象，并探讨了几个潜在的制约因素，包括形态、词汇和概率变量。检查了三个声学参数：发声、/s/与后续元音之间的高频带（4-8 kHz）强度差异，以及/s/中低频带（0-1.5 kHz）强度下降的持续时间。超过三分之一的/s/辅音表现出不间断的发音。所有这三个参数是高度敏感的语速，不太一致，韵律因素，如词的位置和压力。我们还发现，/s/后缀在冗余形态句法语境中比其他词尾/s/段更容易弱化。几个高频词特别容易减弱，但没有观察到一般的概率效应的因素声称有利于减少，如词频，上下文的可预测性或语法类。这些研究结果表明，复杂的变化特征的减少现象，在自发的讲话。
Abstract This study describes the weakening of intervocalic /s/ in the Nijmegen Corpus of Casual Spanish and investigates the role of several potential conditioning factors, including morphological, lexical and probabilistic variables. Three acoustic parameters were examined: voicing, the difference in high-band (4–8 kHz) intensity between /s/ and the following vowel, and the duration of the dip in low-band (0–1.5 kHz) intensity in /s/. Over a third of the /s/ consonants exhibited uninterrupted voicing. All three parameters were highly sensitive to speech rate and, less consistently, to prosodic factors such as word position and stress. We also found that /s/ suffixes in redundant morphosyntactic contexts were more prone to weakening than other word-final /s/ segments. Several high-frequency words were particularly prone to weakening, but no general probabilistic effects were observed for factors claimed to favor reduction such as word frequency, contextual predictability or grammatical class. These findings demonstrate the complex variability characteristic of reduction phenomena in spontaneous speech.
