[A clinical application and study of analysis system of sound spectrography].
OBJECTIVE
The phonetic features were studied for non-velopharyngeal dysfunction in postoperative patients with cleft plate.


METHODS
The feature of velopharyngeal competency of 32 postoperative patients with cleft palate were analyzed with KAY-7800 sound spectrograph, compared with characteristic of 30 subjects with normal phonogram.


RESULTS
There were three types of abnormal phonogram for the postoperative patients of cleft palate with velopharyngeal competence. The heavy noise was a common sight.


CONCLUSIONS
An analytic system of sound spectrography has certain value for evaluation of phonic function in cleft palate patients.
