Static palatograph recording system was used in this study. Palatograms of six normal dentulous adults were made by the recording system during pronounce the following Chinese phonetic alphabets: /S/, /X/, /D/, /J/, /N/, /K/, /R/, /L/. The contact pattern that is the contact area of tongue to palate and tongue to teeth in the palatograms were identified and analysed. The result indicated that the palatograms of the six normal adults are different which can be divided into four types: Type1/S, X/; Type2/D, N, J/; Type 3/K/; Type 4/R, L/.
