Abstract
The paper presents extensions of the single-matrix formulation (Mokhtari et al., 2008, Speech Comm. 50(3) 179 – 190) that enable self-oscillation models of vocal folds, including glottal chinks, to be connected to the vocal tract. It also integrates the case of a local division of the main air path into two lateral channels, as it may occur during the production of lateral approximants. Extensions are detailed by a reformulation of the acoustic conditions at the glottis, and at the upstream connection of bilateral channels. Numerical simulations are provided to validate the simulation framework. The introduction of a zero due to the presence of bilateral channels is confirmed by the simulations. The position of the zero agrees with the theoretical predictions. Simulations of static vowels reveal that the behavior of the vocal folds is qualitatively similar whether they are connected to the single-matrix formulation or to the classic reflection type line analog model. Finally, the acoustic effect of the glottal chink on the production of vowels is highlighted by the simulations: the shortening of the vibrating part of the vocal folds lowers the amplitude of the glottal flow, and therefore lowers the global acoustic level radiated at the lips. It also introduces an offset in the glottal flow waveform.

Simulations of static vowels reveal that the behavior of the vocal folds is qualitatively similar whether they are connected to the single-matrix formulation or to the classic reflection type line analog model. Finally, the acoustic effect of the glottal chink on the production of vowels is highlighted by the simulations: the shortening of the vibrating part of the vocal folds lowers the amplitude of the glottal flow, and therefore lowers the global acoustic level radiated at the lips. It also introduces an offset in the glottal flow waveform.</div></front></TEI><hal api="V3"><titleStmt><title xml:lang="en">Extension of the single-matrix formulation of the vocal tract: consideration of bilateral channels and connection of self-oscillating models of vocal folds with glottal chink</title><author role="aut"><persName><forename type="first">Benjamin</forename><surname>Elie</surname></persName><email></email><idno type="halauthor">1109510</idno><affiliation ref="#struct-420403"></affiliation></author><author role="aut"><persName><forename type="first">Yves</forename><surname>Laprie</surname></persName><email></email><idno type="idhal">yves-laprie</idno><idno type="halauthor">62777</idno><affiliation ref="#struct-420403"></affiliation></author><editor role="depositor"><persName><forename>Benjamin</forename><surname>Elie</surname></persName><email>benjamin.elie@inria.fr</email></editor></titleStmt><editionStmt><edition n="v1" type="current"><date type="whenSubmitted">2015-09-16 11:00:58</date><date type="whenWritten">2015-09-14</date><date type="whenModified">2015-09-23 01:04:04</date><date type="whenReleased">2015-09-22 09:21:27</date><date type="whenProduced">2015-09-14</date><date type="whenEndEmbargoed">2015-09-16</date><ref type="file" target="https://hal.archives-ouvertes.fr/hal-01199792/document"><date notBefore="2015-09-16"></date></ref><ref type="file" subtype="author" n="1" target="https://hal.archives-ouvertes.fr/hal-01199792/file/Article.pdf"><date notBefore="2015-09-16"></date></ref></edition><respStmt><resp>contributor</resp><name key="178810"><persName><forename>Benjamin</forename><surname>Elie</surname></persName><email>benjamin.elie@inria.fr</email></name></respStmt></editionStmt><publicationStmt><distributor>CCSD</distributor><idno type="halId">hal-01199792</idno><idno type="halUri">https://hal.archives-ouvertes.fr/hal-01199792</idno><idno type="halBibtex">elie:hal-01199792</idno><idno type="halRefHtml">2015</idno><idno type="halRef">2015</idno></publicationStmt><seriesStmt><idno type="stamp" n="CNRS">CNRS - Centre national de la recherche scientifique</idno><idno type="stamp" n="INRIA">INRIA - Institut National de Recherche en Informatique et en Automatique</idno><idno type="stamp" n="INRIA-LORRAINE">INRIA Nancy - Grand Est</idno><idno type="stamp" n="INRIA-NANCY-GRAND-EST">INRIA Nancy - Grand Est</idno><idno type="stamp" n="LORIA2">Publications du LORIA</idno><idno type="stamp" n="INRIA_TEST">INRIA - Institut National de Recherche en Informatique et en Automatique</idno><idno type="stamp" n="UNIV-LORRAINE">Université de Lorraine</idno></seriesStmt><notesStmt></notesStmt><sourceDesc><biblStruct><analytic><title xml:lang="en">Extension of the single-matrix formulation of the vocal tract: consideration of bilateral channels and connection of self-oscillating models of vocal folds with glottal chink</title><author role="aut"><persName><forename type="first">Benjamin</forename><surname>Elie</surname></persName><idno type="halAuthorId">1109510</idno><affiliation ref="#struct-420403"></affiliation></author><author role="aut"><persName><forename type="first">Yves</forename><surname>Laprie</surname></persName><idno type="idHal">yves-laprie</idno><idno type="halAuthorId">62777</idno><affiliation ref="#struct-420403"></affiliation></author></analytic><monogr><imprint></imprint></monogr></biblStruct></sourceDesc><profileDesc><langUsage><language ident="en">English</language></langUsage><textClass><keywords scheme="author"><term xml:lang="en">Speech synthesis</term><term xml:lang="en">Vocal folds</term><term xml:lang="en">Glottal chink</term><term xml:lang="en">Lateral consonants</term></keywords><classCode scheme="halDomain" n="phys.meca.acou">Physics [physics]/Mechanics [physics]/Acoustics [physics.class-ph]</classCode><classCode scheme="halTypology" n="UNDEFINED">Preprints, Working Papers, ...</classCode></textClass><abstract xml:lang="en">The paper presents extensions of the single-matrix formulation (Mokhtari et al., 2008, Speech Comm. 50(3) 179 – 190) that enable self-oscillation models of vocal folds, including glottal chinks, to be connected to the vocal tract. It also integrates the case of a local division of the main air path into two lateral channels, as it may occur during the production of lateral approximants. Extensions are detailed by a reformulation of the acoustic conditions at the glottis, and at the upstream connection of bilateral channels. Numerical simulations are provided to validate the simulation framework. The introduction of a zero due to the presence of bilateral channels is confirmed by the simulations. The position of the zero agrees with the theoretical predictions. Simulations of static vowels reveal that the behavior of the vocal folds is qualitatively similar whether they are connected to the single-matrix formulation or to the classic reflection type line analog model. Finally, the acoustic effect of the glottal chink on the production of vowels is highlighted by the simulations: the shortening of the vibrating part of the vocal folds lowers the amplitude of the glottal flow, and therefore lowers the global acoustic level radiated at the lips. It also introduces an offset in the glottal flow waveform.</abstract></profileDesc></hal></record>Pour manipuler ce document sous Unix (Dilib)
