Abstract
Sixty-five males and 38 females 5-15 years of age, mean I.Q. of 93.6, with 8 of the group having hearing loss of 25 db or greater, 8 having clefts of the lip only, 23 of the palate only, and 72 of both lip and palate, with all but 7 having repaired palates, 19 by obturators and 69 by surgical closure, were studied by the Templin Picture Articulation Test, and measurements of oral pressure. X-ray data were obtained for each subject phonating the vowel (u) and sustaining the fricative sound (s). Intra-oral breath pressure was related to velo-pharyngeal competency in articulation scores. Cleft lip subjects only had normal pressures. Measurement of oral breath pressure of speakers with cleft lips and palates can be of major diagnostic value.
