Language is a distinguishing characteristic of our species, and the course its evolution one hardest problems in science. It has long been generally considered that human speech requires low larynx, high larynx nonhuman primates should preclude their producing vowel systems universally found language. Examining vocalizations through acoustic analyses, tongue anatomy, modeling potential, we baboons (Papio papio) produce sounds sharing F1/F2 formant structure [ɨ æ ɑ ɔ u] vowels, similarly with...
Voice identity recognition is vital for social communication, yet its neural encoding mechanisms remain unclear. We investigated whether neurons in the anterior temporal voice area (aTVA) of macaques use norm-based coding (NBC), similar to face vision. Using synthetic vocalizations morphed along trajectories, we found that early neuronal responses (100 150 ms) exhibited V-shaped tuning, with minimal activity average and increased extreme identities. Later (200 ms), a distinct rebound...
The execution of a graphemic sequence is constrained by spatial demands that result in fluctuations letter shape and movement time. When producing two letters (ll, le, or ln) the time first depend on constraints second one. motor system thus anticipates production forthcoming during letter. An experiment reported aim which was to examine whether visual could exploit this anticipatory information predict identity following l. Different ls belonging ll, ln were presented screen. Subjects had...
The development of speech from infancy to adulthood results the interaction neurocognitive factors, by which phonological representations and motor control abilities are gradually acquired, physical involving complex changes in morphology articulatory system. In this article, an articulatory-to-acoustic model, integrating nonuniform vocal tract growth, is used describe effect acoustic perceptual domains. While simulating mature articulators (freezing factors), size shape apparatus varied,...
The generation of area functions from measurements the sagittal section is an important step in study relation between vocal tract geometry and speech acoustics. We present a new model to perform this transformation, inspired by αβ Heinz & Stevens (1965). Our based on analysis cast for large dimensions small CT scans constriction zones three cardinal vowels [i, a, u] French. extracted two sets coefficients, appropriate respectively. then compared predictions with those other models...
Because of recent events and as members the scientific community working in field speech processing, we feel compelled to publicize our views concerning possibility identifying or authenticating a person from his her voice.The need for clear common message was indeed shown by diversity information that has been circulating on this matter media general public over past year.In press release initiated AFCP further elaborated collaboration with SpLC ISCA-SIG, two groups herein discuss present...
The present article aims at exploring the invariant parameters involved in perceptual normalization of French vowels. A set 490 stimuli, including ten vowels /i y u e ø o E oe (inverted c) a/ produced by an articulatory model, simulating seven growth stages and fundamental frequency values, has been submitted as a identification test to 43 subjects. results confirm important effect tonality distance between F1 f0 perceived height. It does not seem, however, that height perception involves...
Fant [G. Fant, Acoustic Theory of Speech Production (Mouton, The Hague, 1960)] has been the first to use four-tube model vocal tract and introduce vocalic nomograms speech production studies. These proved be an efficient tool for study articulatory–acoustic relationships. This paper deals with particular regions these nomograms, referred as focal points. are points where formant convergences occur affiliations between formants cavities exchanged. A appropriate nonsense words confirmed...
We investigated how visual processes exploit specific anticipatory movements observed in handwriting gestures. Previous research has shown that the kinematic information contained downstroke of an l is exploited to predict identity forthcoming letter. Here, we determined moment at which prediction takes place. Two between-letter effects were examined: changes size (ll vs le) and rotation direction (le ln). Results show with only 75% trajectory (or 60% time) subjects are already capable...
