F2/F3 d'occlusives sonores chez des locuteurs porteurs de fente palatine (F2/F3 of voiced plosives and F1/F2 of vowel in VCV Sequences in Children with a Cleft Palate-An acoustic Study) [in French]

________________________________________________________________________________________________________ F2/F3 of voiced plosives and F1/F2 of vowel in VCV Sequences in Children with a Cleft Palate-An acoustic Study The aim of this acoustic study is to examine place of articulation during the production of voiced plosives by children with a cleft palate. The data are compared with those obtained from control children without speech pathological problems. Formant values of F2 and F3 are measured at burst-release of the plosives. Analyses are carried out for fifty-two children, divided into two groups, ranging from 9 to 18 years old. Each group of twenty-six kids comprised children with a cleft palate or cleft lip and palate, and children without any speech disorder. Results reveal differences in F2/F3 values between impaired children and unimpaired ones, and also between the different age groups, for impaired children. Differences in articulatory strategies are inferred from analyses of F2/F3 relations. MOTS-CLES : fente palatine, formants, occlusives, transition, enfant, phonétique clinique
