The pronunciation of consonants /s/, /t/, /j/, /sh/ were detected and the different formant parameters(F1 and F2) were analyzed by the computer speech analytical system. The comfort levels of 4 major connectors were compared by questionnaire survey.</p><p><b>RESULTS</b>1)There was no significant difference(P5).05) in pronunciation of consonants /s/, /sh/, /t/(F1 and F2) among the 4 types of connectors whatever wearing or not, but there was significant difference (P < 0.05) in pronunciation of consonant /j/ among wearing type 3, type 4 and no wearing. 2)There was no significant difference in comfort level (P > 0.05) among the four connectors.</p><p><b>CONCLUSION</b>The effect on pronunciation of patients with Kennedy I deletion was less when wearing the first and the second types of connectors than that of wearing the third and the fourth types of connectors.
