Language-specific maximal size restrictions on syllables have been defined using frames such as moraic structure. In General American English, a trimoraic syllable template makes largely successful predictions about contexts where tense/lax vowel contrasts are neutralised, but neutralisation preceding a coda rhotic has not been adequately explained. We attribute the apparent special properties of coda /ɹ/ to two characteristics of its representation, informed by our articulatory investigation: sequential coordination of dorsal and coronal subsegmental units and a high blending strength specification, corresponding to high coarticulatory dominance. Characteristics of coda laterals are compared. Our approach employs phonological representations where sequencing is encoded directly among subsegments, and coordination is sensitive to strength. Mora assignment is computed over sequencing of subsegments, predicting that complex segments may be bimoraic. The account brings phonotactics for rhymes with postvocalic liquids into line with the trimoraic template, and supports representing coordination and strength at the subsegmental level.

美式英语韵律中rhotics的组织和结构

已使用诸如 moraic 结构之类的框架定义了特定于语言的音节最大大小限制。在通用美式英语中,三节音节模板在很大程度上成功地预测了紧张/松散元音对比被中和的上下文,但在尾韵之前的中和尚未得到充分解释。我们将尾音 /ɹ/ 的明显特殊属性归因于其表示的两个特征,这是由我们的发音研究得出的:背侧和冠状亚节段单位的顺序协调和高混合强度规范,对应于高共同发音优势。比较了尾端的特征。我们的方法采用语音表示,其中序列直接在子段之间编码,并且协调对强度敏感。Mora 分配是通过子段的排序计算的,预测复杂的段可能是双峰的。该帐户将带有后声部液体的押韵的音位法与三模体模板保持一致,并支持在子段级别上表示协调性和强度。
