Voice Quality

By John H. Esling, Scott R. Moisik, Allison Benner, Lise Crevier-Buchman

Voice Quality "The first description of voice quality production in forty years, this book provides a new framework for its study: The Laryngeal Articulator Model. Informed by instrumental examinations of the laryngeal articulatory mechanism, it revises our understanding of articulatory postures to explain the actions, vibrations and resonances generated in the epilarynx and pharynx."

Abstract: This thesis investigates the following research questions: (1) Does Korean have a metrical structure? (2) If so, what are its acoustic correlates and how do they compare to English? (3) How does it interact with phrasal prosody? In addressing these issues, I first re-examine the identity of the so-called 'long' vowel in Korean, and argue that it is a phonetic duration derived from an underlying accent on surface. The phonological argument is based on a reanalysis of what has been traditionally called 'vowel shortening' phenomena in verb stems and compounds as 'stress shift'. I describe phonetic experiments to verify the proposed phonological analysis, where I compare the acoustic properties of the so-called 'long' and 'short' (i.e. stressed and unstressed) vowels of Korean. To compare the results with a well-known stress system, I describe a parallel experiment on English. I adopt the following two experimental methods: (1) The location of the target word is varied in three different prosodic positions. (2) The data are analyzed with two complementary methods: Direct Comparison Method (e.g. 'per' of 'perMIT' vs. 'PER' of 'PERmit') and Relative Comparison Method (e.g. 'per' of 'perMIT' vs. 'MIT' of 'perMIT'). The overall results suggest that both Korean and English adopt longer duration, higher fundamental frequency, and greater intensity for the stressed vowels. However they differ in the details: (1) Korean has a greater phrase final lengthening effect than English. (2) In Korean, the phrase initial rising tone overrides the effects of stress. (3) Pitch plays a more important role in English than in Korean. Finally, I investigate the phrasal prosody and show the following: (1) Intensification and focus use different phonetic cues (duration and pitch movement, respectively), but both of them respect metrical structure. (2) Vocative chant reflects the special status of the stressed syllable in duration and pitch. In the conclusion, implications of the proposed theory are discussed on the prosodic hierarchy of Korean and the prosodic typology.
