title: [Study on articulation characteristics of patients after cleft palate repair in Henan province].
abstract: OBJECTIVE
  To establish the pathological speech characteristic of patients after cleft plate repair in Henan province by unusual speech frequency and vowel formants.
  
  
  METHODS
  One hundred normal speech patients and 121 patients after cleft palate repair were selected, their formant frequency of vowels/ a,o,e,i,u,ü/ were obtained. The pathological speech frequency was collected in 121 postoperative patients. The acoustic features of the vowel were compared by SPSS17.0 software package with two independent sample t test.
  
  
  RESULTS
  According to articulation position, 21.9% of misarticulation of postoperative patients occurred in dental consonants, 5.2% in retroflex consonants, 21.6% in alveolar consonants, 19.2% in palatal consonants, 12.9% in velar consonants and 6.6% in dorsum consonants. The average value of F2 of/a, o, e, u/did not show significant difference between the two groups (P>0.05).The difference of average value of F2 of /i,ü/ was significant (P<0.05). The average value of F1 of/a, o, e, I, u/did not show significant difference between the two groups (P>0.05).Except /a/,the average value of F3 of vowel /o, e, i, u, ü/showed significant difference between the two groups (P<0.05).
  
  
  CONCLUSIONS
  Misarticulation of patients after cleft palate repair in Henan province mainly occurred in dental consonants, alveolar consonants and palatal consonants; tongue over curly can be observed in operated patients with cleft palate. There was no significant difference between the two groups in mouth opening.
