To explore the developing rule of formants of core vowels with age, and difference with gender. 2492 normal people were randomly selected with 1318 males and 93 females,and divided to 4 groups according to age. /a/,/i/,/u/ of each child was recorded. Using D1200 to record normatively, reading data of formants in Real Analysis. Datawere analysis by SPSS13.0. 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). (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.
