High Prussian, a variety of East Central German, has a segmentally opaque process of final devoicing: Only some forms with underlyingly voiced obstruents devoice at the end of a word. This phenomenon can also be observed in some morphological alternations where simplex forms show final devoicing but complex ones do not. This paper provides a metrical analysis of final devoicing and two related phenomena: spirantization, and an interaction of vowel length in high vowels and obstruent voicing. It is claimed that nondevoicing items contain disyllabic foot templates and that word-final consonants are then syllabified as onsets of empty-headed word-final syllables. The analysis demonstrates how evidence from West Germanic dialects can contribute to our understanding of the phonology of laryngeal features and to the role that metrical structure can play in shaping phonological alternations.*

高普鲁士语中最终去清的明显例外：度量分析

高普鲁士语是东中德语的一个变体，有一个不透明的最终清音过程：只有一些带有潜在浊音阻塞的形式在词尾清音。这种现象也可以在一些形态交替中观察到，其中单纯形形式显示出最终的去核，而复杂的形式则没有。本文提供了对最终清音和两个相关现象的度量分析：spirantization，以及高元音中元音长度和阻塞浊音的相互作用。据称，nondevoicing 项目包含双音节脚模板，然后词尾辅音被音节化为空头词尾音节的开头。
