This study compared F0 and the first three formants of eight Korean monophthongs produced by nine transgenters (male to female) to those of eighteen normal adults. Voice analysis was done by Praa (version 4.4049). A one-way ANOVA wih Turkey HSD post hoc tests were performed to determine statistical differences in F0 and forma values obtained from transgender, and normal male and female subjects. Results indicated that there was no significant difference in F1 of /u/, /Λ/, and /o/, F2 of /u/, /Λ/, and /i/ and F3 of /u/ among the 3 groups (transgender, normal males and normal females). However, in the comparison of transgender vs. males, a significant difference was observed in F0 of /o/, and F2 of /i/, /a/, /e/, and /ae/ an F3 of /e/. Furthermore in the comparison of transgender vs. females, a significant difference was also observed in F0 of all vowels, F1 of /i/, /a/, /e/, /ae/, and /i/, F2 of /i/, an /ae/, an F3 of /i/, /a/, /Λ/, /e/, /ae/, /i/, an /o/. Also, perceptual judgment of the transgender´ voice came out somewhat correlated strongly with their F0 values but not much with the formant values. It was concluded that he transgender´ acoustic parameters are plead in between those of the normal males and females in terms of fundamental and formant frequency analyses of vowels. Thus, it was assumed that those differences might stem from the transgender´ original big resonating cavities.
