Patterns of articulation abilities in speakers with cleft palate.

The purpose of this study was to report the articulation scores of 351 subjects with cleft palate from the ages of 2-6 to 18-0. Analysis of the data indicate that, as a group, subjects with cleft palate are retarded in articulation skills. However, they continue to improve in this regard past the age at which normal speakers have achieved articulation maturation. This information should be compared with that acquired from other centers in order to determine how typical these findings are.
