OBJECTIVE: To explore the normal vocal acoustic parameters and electroglottographic (EGG) parameters and their differences in normal children of the Han, the Naxi, the Bai nationality.
METHOD: By using computer and Dr. speech software, We studied six parameters of voice acoustic and the E.G.G. in 951 children (Han 342, Naxi 224, Bai 385), aged 4-8 years old. We also examined 30 cases who suffered from vocal nodule and local proliferation.
RESULT: The major parameters 1. Jitter, 2. Shimmer, 3. Mean F0, 4. SD F0, 5. NNE) of the voice acoustic and E.G.G. of the three nationality.
CONCLUSION: 1. All parameters in Han nationality school-age children and preschool children were not different in years old. But Naxi and Bai nationality school-age children's Mean F0 and SD F0 were different from preschool children. The parameters(Mean F0, SD F0) of school-age children in Han, Naxi and Bai nationality were significant different. 2. The tested parameters were significant different between normal children of the Han nationality and the vocal nodule patients.
