The acoustic parameters of six Korean VOWCIS produced by a healthy male were analyzed to elaborately synthesize the six vowels by a formant synthesis method. Then, FI and F2 values of the synthesis file were modified by 50 Hz while F3, by 100 Hz over and under the original values but not interfering adjacenl formants to obtain 270 stimuli, Twenty male and females listened to the original k'owel followed by tbe corresponding synthesized one and judged whether they sounded qualitatively 'similar'

Females indicated 40 Hz higher range than those of males. The ranges supported the nonlinearity of human auditory scale to the speech sound.
