This study compared pitch range, total duration of utterances, pause, boundary tones and mean duration of intonation final syllables of 4 sentences produced by 5 transgenders (male to female) to those of twenty normal adults. Voice analysis was performed by Praat (version 4.049). The results showed that there were differences in pitch range, total duration of utterances, pause, boundary tones and mean duration of intonation final syllables among the 3 groups(transgenders, normal males and normal females).
