Abstract

_________________________________________________________________________________________________________ Study of the coarticulation CV within Italian adult stutterers The coarticulation of the stuttered speech shows distinctive characteristics in its dysfluent aspects as well as in its fluent ones. The present survey is about the coarticulation of fluent sequences tested in Italian adult stutterers. The tested subjects had to repeat CV syllables under two different feedbacks : normal, then with an altered auditory feedback. The results show that the coarticulation tends to be less important in adult stutterers compared to that of fluent adults. This difference is all the more perceptible as the consonnant, in sequence CV, is a back one. The condition of the altered feedback enables the stutterers to have decrease in variability. And, the degree of coarticulation tends to be closer to that of the fluents one, for the sequences with the back consonant. Discussion is open about the motor control of the stuttered speech. MOTS-CLES : bégaiement, disfluences, coarticulation, retour auditif modifié. KEYWORDS : stuttering, disfluencies, coarticulation, altered auditory feedback. 1

Cette étude s’intéresse à la coarticulation des séquences fluentes d’adultes bègues italiens. Les sujets doivent répéter des syllabes CV dans deux conditions de retour auditif : normales, puis avec feedback auditif modifié. Les résultats montrent une tendance à une coarticulation moins importante chez les adultes bègues par rapport à leurs homologues fluents. Cette différence est d’autant plus marquée que la consonne, de la séquence CV, est postérieure. La condition de feedback modifié, permet chez les bègues, une réduction de la variabilité. Egalement, le degré de coarticulation a tendance à se rapprocher de celui des fluents pour les séquences avec consonne postérieure. Une discussion est faite autour du contrôle moteur de la parole bègue.

Wingate (1988), dans son hypothèse de la ligne de faille, stipule que les 257 disfluences puissent être considérées comme une perturbation du phénomène de coarticulation. Plusieurs études confirment cette hypothèse non seulement dans la parole disfluente (Howell et Vause, 1986) des sujets bègues, mais aussi dans leur parole fluente (Zmarich et al., 2006 ; Hirsch, 2007 ). Par ailleurs, les modifications du feedback auditif sont reconnues pour améliorer la fluence des personnes bègues. Il paraît donc judicieux d’étudier la parole bègue dans ses aspects fluents, dans des conditions …
