Efforts de production de parole chez les personnes qui bégaient

Abstract : Speech production efforts in people who stutter. This study aims at objecting and quantifying the visible oro-facial tensions that are commonly described in people who stutter (PWS), by comparing the aerodynamic, laryngeal and articulatory efforts of speech production between PWS and normo-fluent people (NFP). 4 adult PWS and 4 NFP were recorded, while producing words beginning with labial stop consonants in a reading task and a semi-spontaneous task. Contrary to our expectations, PWS demonstrated less intra-oral pressure and interlip force (measured with a force sensor) than NFP (with comparable syllable intensity, though). No significant difference in intra-oral pressure and interlip force was observed between the disfluent vs. perceptually fluent syllables produced by PWS. However, the differences in intra-oral pressure observed between PWS and NFP were greater on complex syllables (beginning with a consonant cluster) and for the semi-spontaneous task. The electroglottographic data is currently being analyzed and will be presented at the conference.
