The Segment in Phonetics and Phonology unravels exactly what the segment is and on what levels it exists, approaching the study of the segment with theoretical, empirical, and methodological heterogeneity as its guiding principle. A deliberately eclectic approach to the study of the segment that investigates exactly what the segment is and on what level it exists Includes new research data from a diverse range of fields such as experimental psycholinguistics, language acquisition, and mathematical theories of communication Represents the major theoretical models of phonology, including Articulatory Phonology, Optimality Theory, Laboratory Phonology and Generative Phonology Examines both well-studied languages like English, Chinese, and Japanese and under-studied languages such as Southern Sierra Miwok, Pari, and American Sign Language
