Physical modeling of vowel-bilabial plosive sound production

Downstream of the vocal folds, it is often assumed that all the kinetic energy of the glottal jet is dissipated by turbulence. Although this assumption is reasonable for normal voicing, there are many configurations for which a constriction or even an occlusion of the vocal tract occurs and leads to a significant pressure recovery. Such a phenomenon occurs during the production of vowel-bilabia...

Rapid Change in Articulatory Lip Movement Induced by Preceding Auditory Feedback during Production of Bilabial Plosives

BACKGROUND There has been plentiful evidence of kinesthetically induced rapid compensation for unanticipated perturbation in speech articulatory movements. However, the role of auditory information in stabilizing articulation has been little studied except for the control of voice fundamental frequency, voice amplitude and vowel formant frequencies. Although the influence of auditory informatio...

Proceedings of Meetings on Acoustics

The context of this study is the physical modeling of speech production. The first step of our approach is to realize in-vivo measurements during the production of the vowel-consonant-vowel sequence /apa/. This measurements concerns intra-oral pressure, acoustic pressure radiated at the lips and labial parameters (aperture and width of the lips) derived from a high-speed video recording of the ...

Relative Timing of Bilabial Gesture in Finnish

The Embodied Task Dynamic model of gestural sequencing predicts that an intervocalic consonantal lip closing gesture should come later if the tongue is moving from /i/ to /a/ rather than from /a/ to /i/ because this relation is more efficient in terms of production and perceptibility. We tested this prediction for Finnish /ipa/ and /api/ using EMA to track articulation. The results confirmed th...
