Results of systematic speech sound monitoring in children with cleft palate.

Using our monitoring system, we report the articulation results in 208 children with competent velopharyngeal function after surgery of cleft palate. The number of children who showed normal articulation at each test during the monitoring period was 138. The other 79 children included 37 who acquired normal articulation after training and whose misarticulation disappeared without training. Factors related to their misarticulation are discussed.
