Although a growing body of literature in formal phonology has espoused the view that phonological knowledge is gradient and probabilistic, this perspective remains somewhat controversial. This paper provides further empirical support for this strand of work: it offers an analysis of the gradient deletion of word-final schwa in Southern French, using a corpus containing 7787 data points obtained from 45 subjects spread over three dialectal areas (the Basque Country, Languedoc and Provence). In addition to confirming or nuancing previous findings about the role of several phonological and non-phonological variables, the study demonstrates the influence of lexical frequency, grammatical category, sonority and the feature specification of the consonant before schwa.

尽管越来越多的正式音韵学文献支持音韵知识是梯度和概率的观点，但这种观点仍然存在争议。本文为这一系列工作提供了进一步的实证支持：它使用包含来自分布在三个方言地区（巴斯克地区，朗格多克和普罗旺斯）。除了确认或详细说明先前关于几个语音和非语音变量的作用的发现外，该研究还证明了词汇频率、语法类别、响度和 schwa 之前辅音的特征规范的影响。
