Methods: Misarticulation was examined by acoustic analysis technology when pronouncing chinese consonant /t/, /s/ and /d/ in 72 post-operation CP children and 9 normal children. And the pronunciation was characteristiced by the voice starting time(VOT) and the distribution of strong force frequency etc. Results:There were less VOT time and append lower strong force frequency in cleft palate children. Conclusion: The characteristic of pronunciation compensation of the patients with CP is the two-time-disblock. f
