Children with submucous cleft palate (S. M. C. P.) and congenital velopharyngeal incompetence (C. V. P. I.) present not only with articulatory problems but also with developmental problems. The purpose of this study is to investigate their mental and physical developmental problems, characteristics of articulatory errors, and methods of speech training. The results were as follows.1) S. M. C. P. and C. V. P. I. children have often mental and physical retardation. Fifty-eight per cent of the S. M. C. P. and 72% of the C. V. P. I. children show low intelligence (under I. Q. 90).2) The characteristics of articulatory errors were of no differential diagnostic significance between S. M. C. P. and C. V. P. I., but (1) children with distinct velopharyngeal incompetence produce distorted plosive sounds (/p/, /t/, /k/). (2) Slight incompetence is often accompanied by distortion of fricative sound (/∫/).3) If children exhibit many articulatory errors, it is unnecessary to make active speech training for all errors. To children under 6 years old we train for consonants /p/, /t/, /k/, occasionally /∫/, and to older children than 6 years old /p/, /t/, /k/, /∫/, /s/, and /t∫/, /ts/ if necessary.
