Experiment 
We can confirm the difference in the speech waves.
This figure shows experimental results of Formant distribution of high school students(13 males)
“a” and “u” are similar and “e” and “o” are similar.
We can confirm the difference in the speech waves. This figure shows experimental results of Formant distribution of high school students(10 females)
We can confirm non-uniform acousic differences between male and female vowels.
Female vowels are higher formant freguencies than male vowels.
You can be applied to the generation of voiceprint recognition and sound by using the formant frequency.
