Using D1200 to record normatively, reading data of formants in Real Analysis. Datawere analysis by SPSS13.0. RESULT: Formants of Core vowels had significant difference with age (P < 0.05), generally having a decreasing trend mainly with F1,F2 and deltaA (A1-A2) were different significantly as to gender; There were also significant difference between the formants of the core vowels (P < 0.05). CONCLUSION: (1) There are significant effect of age,gender and core vowels(a,i,u)on F1, F2; (2) There are parallel correlation between developing trend of F1, F2 and that of F0.
