A unified mode of representation of laryngeal features

This study attempts to provide the phonological and phonetic representations of laryngeal features in a unified mode. That is, the same format of a categorical representation is given for both representations. Two tasks are performed in this study: an investigation of three major laryngeal phenomena, aspiration, voicing, and glottalization, in various languages, an evaluation of the framework of the aperture positional theory, which makes reference to internal structure of a segment.In the discussion of laryngeal phenomena within the aperture positional framework, in which a non-continuant segment is represented as sequence of a closure phase and a release phase, a revision of the closure portion is made. A branching structure of the closure is proposed. Within the revised aperture framework, new forms of the phonological and categorical phonetic representations are presented, reflecting phonological patterns, as well as phonetic properties.By and large, bipositional closure node is more adequate in explaining a wide range of laryngeal phenomena found across languages.U of I OnlyETDs are only available to UIUC Users without author permissio
