The Dispersion-Focalization Theory of vowel systems
- J. Schwartz, L. Boë, N. Vallée, C. Abry
- Physics

The Dispersion-Focalization Theory (DFT) attempts to predict vowel systems based on the minimization of an energy function summing two perceptual components : global dispersion , which is based on…

This paper proposes an original approach using an efficient nonlinear dimension reduction algorithm (“curvilinear components analysis”) in order to increase the performances of the two AV architectures and respects the “synergy” criterion for the two most used architectures.
The speech focus position effect on jaw-finger coordination in a pointing task.
- Amélie Rochet-Capellan, R. Laboissière, A. Galvàn, J. Schwartz
- PhysicsJournal of Speech, Language and Hearing Research
- 1 December 2008
For both stress conditions, the stressed syllable occurs within the finger-target alignment period because of tight finger-jaw coordination, interpreted as evidence for an anchoring of the speech deictic site (part of speech that shows) in the pointing gesture.
Functional MRI assessment of orofacial articulators: Neural correlates of lip, jaw, larynx, and tongue movements

Evidence is provided for a core neural network involved in laryngeal and supralaryngeAL motor control and further refine the sensorimotor somatotopic organization of orofacial articulators.
Major trends in vowel system inventories

- 1 July 1997
The search for universal tendencies in the languages of the world is a necessary anchor point for any theoretical approach to phonetics. The present typology of vowel systems aims to provide material…
Audio-visual enhancement of speech in noise.
- Laurent Girin, J. Schwartz, G. Feng
- Computer ScienceJournal of the Acoustical Society of America
- 6 June 2001
An audio-visual approach to the problem of speech enhancement in noise is considered, since it has been demonstrated in several studies that viewing the speaker's face improves message intelligibility, especially in noisy environments.
Complementarity and synergy in bimodal speech: auditory, visual, and audio-visual identification of French oral vowels in noise.
- J. Robert-Ribes, J. Schwartz, T. Lallouache, P. Escudier
- PhysicsJournal of the Acoustical Society of America
- 27 May 1998
A set of experiments on the auditory, visual, and audio-visual identification of vowels embedded in various amounts of noise demonstrate that complementarity and synergy in bimodal speech appear to hold for a bundle of individual phonetic features describing place contrasts in oral vowels.
Binding and unbinding the auditory and visual streams in the McGurk effect.
- O. Nahorna, F. Berthommier, J. Schwartz
- PhysicsJournal of the Acoustical Society of America
- 8 August 2012
If a given McGurK stimulus is preceded by an incoherent audiovisual context, the amount of McGurk effect is largely reduced and the data are interpreted in the framework of a two-stage "binding and fusion" model for audiovISual speech perception.
