Question

The distinction between the voice of a man and that of woman is possible because of difference between

Answer 1

The 2 vocal properties are intensity(loudness) and frequency(pitch).Pitch of a man's voice fall under low frequency,where as woman's voice is of the high pitch type.Pitch and intensity are proportional to each other. As seen in the spectrograms beneath,we can compare the intensities of male vs female voice.Female's voice has more frequency components compared to men.Women speak at one octave higher than men.Even though in the graphs underneath show that a man's voice (while screaming) has a 1 high frequency component ,and than has low intensity after that.Whereas,female's voice has a band of median intensity and gradually tapers towards end.
