Allophonic patterns of variation in English laterals have been well studied in phonetics and phonology for decades, but establishing broad generalizations across varieties has proven challenging. In this study, a typology of onset/coda lateral distinctions in English is advanced using crowdsourced recordings from 95 speakers across twelve dialects of Anglo (UK) English. Results confirm the existence of dialects with and without onset/coda distinctions, and conditional inference trees are used to identify three main patterns in the data: (1) clear onsets and dark codas; (2) intermediate/dark onsets and dark codas, but with a positional distinction intact; and (3) dark onsets and dark codas, with minimal or no distinctions between positions.

十二种英语方言中的分支词类型学。

数十年来，在语音和音系学上已经很好地研究了英语侧向变化的同音异形模式，但事实证明，要建立跨变体的广泛概括已被证明具有挑战性。在这项研究中，使用来自英语（英语）（英语）（英语）（英语）（英语）（英语）（英语）（英语））12种方言的95位演讲者的众包录音，对英语中的发作/尾声旁侧区别进行了分类。结果证实了方言存在和不存在起始/尾声的区别，并且条件推断树用于识别数据中的三个主要模式：（1）清晰的起始词和深色尾声；（2）中间/深色发作和深色尾巴，但位置区别完整；（3）深色发作和深色尾巴，位置之间的区别很小或没有区别。
