The Dispersion-Focalization Theory of vowel systems
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 onExpand
Major trends in vowel system inventories
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 materialExpand
The potential Neandertal vowel space was as large as that of modern humans
TLDR
Using a new anthropomorphic articulatory model, it is inferred that the vowel space of the Neandertal male was no smaller than that of a modern human, and vowel simulations are presented to corroborate this hypothesis. Expand
"Laws" for lips
TLDR
The most interesting relation between front and profile views is the inverse correlation between width and protrusion (on condition that corner protrusion is chosen), which means prediction of area is possible through profile measurements namely with height and corner protruding. Expand
Vocal tract area function estimation from midsagittal dimensions with CT scans and a vocal tract cast: modeling the transition with two sets of coefficients.
TLDR
A new model to perform this transformation, inspired by the alpha beta model of Heinz & Stevens (1965), based on analysis of a vocal tract cast for large sagittal dimensions and on CT scans of the vocal tract constriction zones for the three cardinal vowels of French is presented. Expand
Articulatory-acoustic relationships during vocal tract growth for French vowels: Analysis of real data and simulations with an articulatory model
TLDR
Perceptual tests show that achieving focalization results in a lower intelligibility for the children than for the adults, and simulations using an articulatory model demonstrate that the realization of the focalization feature may require different articulatory gestures for young children compared to adults.

The vocal tract of newborn humans and Neanderthals: Acoustic capabilities and consequences for the debate on the origin of language. A reply to Lieberman (2007a)
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository. Authors requiring further informationExpand
MODELLING THE GROWTH OF THE VOCAL TRACT VOWEL SPACES OF NEWLY-BORN INFANTS AND ADULTS CONSEQUENCES FOR ONTOGENESIS AND PHYLOGENESIS
If newly-born infants had the same sensorimotor control capabilities as adults, would their vocal tracts enable them to produce the same range of [i a u] vowel contrasts? Has increasing the volume ofExpand
Visual Perception of Motor Anticipation in Cursive Handwriting: Influence of Spatial and Movement Information on the Prediction of Forthcoming Letters
TLDR
The ability to predict the forthcoming letter seems to be mediated by implicit knowledge on motor anticipation rules, specifically on the shape of the l and/or the movement that produced it. Expand
Asymmetries in vowel perception, in the context of the Dispersion-Focalisation Theory
TLDR
It is shown that focalisation, that is the convergence between two consecutive formants in a vowel spectrum, is likely to provide the ground for anchor vowels, by increasing their perceptual salience. Expand
