  • Title: Pre-speech in children with cleft lip and palate or cleft palate only: phonetic analysis related to morphologic and functional factors.
    Author: Lohmander-Agerskov A, Söderpalm E, Friede H, Persson EC, Lilja J.
    Journal: Cleft Palate Craniofac J; 1994 Jul; 31(4):271-9. PubMed ID: 7918522.
    Abstract:
    Pre-speech in 35 children with clefts of the lip and palate or palate only were analyzed for place and manner of articulation. Transcriptions were made from tape recorded babbling sequences. Two children without clefts were used as reference. All of the children with clefts were treated according to a regimen of early surgical repair of the velum cleft and delayed closure of the cleft in the hard palate. The frequency of selected phonetic features was calculated. Correlations between phonetic/perceptual and functional and morphological factors were tested. Supraglottal articulation dominated among all the children indicating a sufficient velopharyngeal mechanism. The results also showed correlations between cleft type and place of articulation. Anteriorly placed sounds (i.e., bilabial, dental, and alveolar sounds) occurred frequently among the children with cleft palate only and in the noncleft children. In children with cleft lip and palate, posteriorly placed articulations predominated. It was postulated that early intervention may have a positive effect on articulatory development.
