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 dissertation investigates how lexical stress in Spanish is
phonetically manifested within the syllable, and how stress manifestation
interacts with other prosodic effects, such as phrasal accent and initial
word-boundary effects. One of the challenges in the study of prosody is the
fact that multiple prosodic factors induce variation in a limited number of
phonetic dimensions. For this reason, results in the literature have often
been inconclusive or conflicting. The disentanglement of these prosodic
effects will help us understand the complex nature of prosody.

The results of this study show that stress effects can be identified
independently of phrasal level prominence (accent) and prosodic-boundary
effects (position in word). Among the prosodic effects, durational and
spectral properties clearly differentiate stressed onset and vowel from
their unstressed counterparts, but intensity does not. In addition,
similarities between stress and accent effects, grouped as 'prominence
effects', are distinguished from word-level boundary effects that are
conditioned by accent conditions. Finally, the results indicate that
syllable constituency can be involved in prosodic manifestation, possibly
constrained by higher-level prosody, such as isochrony (stress-timed vs.
syllable-timed rhythms). We identified apparent complementarity between
syllable constituents in the stress manifestation of two dialects of
Spanish, which can be attributed to two structural motivations. On the one
hand, syllable constituency is involved in segmental variation at the
lexical-level (stress); and on the other hand, a higher-level prosody
(isochronous rhythm) can play a role as an upper bound in constraining the
variability. A gestural account is provided to accommodate the asymmetric
contribution of syllable constituents to the temporal manifestation of stress.

The investigation of the phonetics of prosody manifestation provides us
insight into interrelations among prosodic factors, and the systematicity
behind the complexity of prosodic effects. It is hoped that this
dissertation contributes to a better understanding of prosody as a
well-structured grammatical component, and its connections to segmental
phenomena in languages.
