Abstract

_________________________________________________________________________________________________________ French Cued Speech perception and expertise effect in hearing people Since French Cued Speech (CS) is multi-signal (lip movements and CS gestures), we conducted an eye tracking study to examine whether this perception involves integrative treatment and how expertise affects it in normally-hearing participants. Our paradigm consisted in a word/pseudowords (presented in video clip, without sound) identification task. It included three conditions: a CS condition, a meaningless gesture condition, and a lipreading condition. After each video, participants were presented three options (i.e. correct answer, labial distractor and manual distractor) and instructed to select the correct one. Behavioral and eye tracking data were collected on three groups of normally-hearing partcipants: experts in CS, beginners in CS, and completely naïve toward CS. The first results, very promising, suggest that only experts and beginners integrate CS gestural and labial information, and that the relative weight of labial and manual information seems to change with expertise.

Notre paradigme, une tâche d’identification de mots/pseudomots (présentés sous forme de vidéo sans son), comportait trois conditions : une condition lecture labiale et code LPC, une condition lecture labiale et geste non significatif, et une condition lecture labiale seule. Après chaque vidéo le participant devait faire un choix parmi trois propositions : réponse correcte, distracteur labial et distracteur manuel. Les données comportementales et psychophysiologiques ont été récoltées auprès de trois groupes d’adultes normo-entendants : des experts LPC, des débutants LPC et des naïfs LPC. Les premiers résultats, prometteurs, suggèrent que seuls les experts et les débutants LPC intègrent l’information labiale et manuelle, et que le poids de chacune de ces informations évolue avec l’expertise.

Or la lecture labiale seule, du fait de son caractère incomplet et ambigu ne permet pas la perception de tous les contrastes phonémiques. Les personnes sourdes ont donc une perception très difficile de la parole par le biais de la lecture labiale. Afin de pallier à ce déficit, Cornett (1967) a inventé un système d’aide à la perception de la parole. Ce système réduit l’ambiguïté de la lecture labiale en rendant visibles tous les contrastes phonologiques de la langue orale à l’aide …
