"A dissertation submitted in partial fulfillment of the requirements for the Bachelor of Science (Speech and Hearing Sciences), The University of Hong Kong, June 30, 2010."Thesis (B.Sc)--University of Hong Kong, 2010.Includes bibliographical references (p. 21-23).This study aimed to investigate the relationship between different types of singing voice in
each gender, and the vocal tract dimensions, the length and volume, and the formant
frequencies of vowels. Twenty-five sopranos, 11 mezzo-sopranos, 17 tenors, and 12 baritones
were included in the study. The participants’ vocal tract dimensions were measured by
acoustic reflection technique (ART). They were also asked to speak vowels and sing the song,
Happy Birthday”. The first three formant frequencies of four recorded vowels were obtained
by Praat software and used to correlate with the vocal tract findings. The results showed that
baritones had larger oral volume and total vocal tract volume than tenors significantly.
Besides, sopranos had generally higher formant frequencies than mezzo-sopranos. The
findings of current study provided insights on the objective method in singing voice
