Abstract Catalan has a [ʒ] ~ [t͡ʃ] alternation that has traditionally been viewed as the consequence of final affrication of an underlying /ʒ/, a fortition operation, followed by general devoicing of obstruents. This interpretation has been held in classical generative rule-based approaches and also in autosegmental models, amounting either to a highly specific process or, when an attempt is made to generalize it, to wrong predictions; these shortcomings are also applicable to optimality-theoretic analyses. Following ideas in (Wheeler, Max W. 2005. The phonology of Catalan. Oxford: Oxford University Press), we propose that underlying affricates are subject to intervocalic lenition triggered by independently motivated general constraints. Sequences of a stop followed by a fricative can become affricates but cannot be affected by lenition. The interaction between affricates and gemination is also discussed.

加泰罗尼亚语的磨擦-亲子交替

摘要加泰罗尼亚语具有[ʒ]〜[t͡ʃ]交替的现象，传统上将其视为底层/ʒ/的最终隶属关系，强化操作以及随后对淫秽物进行清水处理的结果。这种解释已经在基于规则的经典生成规则方法和自动分段模型中进行，或者说是高度特定的过程，或者当试图将其概括时，就意味着错误的预测。这些缺点也适用于最优性理论分析。遵循（Wheeler，Max W. 2005.加泰罗尼亚语的音系。牛津：牛津大学出版社）中的思想，我们建议潜在的下属成员受到独立动机的一般约束所触发的言语交往。停顿后再出现摩擦音的顺序可能会变得很容易，但不会受到升职的影响。
