Question

why male voice is deeper and female voice is high pitched?

Answer 1

It's not easy choosing a guy. Do you go for the big man with the deep voice, strong jawline and pugnacious streak, or the nice sensitive chap with the squeaky voice who'll take good care of you, but then run away when there's a fight in the offing?

Researchers at Aberdeen University have confirmed that women are attracted to guys with deep voices – as long as they say nice things. But it seems a woman's preferred pitch in a man's voice depends on the pitch of her own voice.

The researchers measured the average voice pitch of 113 heterosexual female undergraduates as they spoke vowel sounds, read a standard sentence and a standard passage of text.

The women then listened to recordings of four men saying either "I really like you", or "I really don't like you", and scored their preferences. The voice recordings had been digitally altered to sound more masculine or more feminine by increasing or decreasing their pitch.

Answer 2

Here is the answer...

In general, females have smaller larynx's and so, smaller vocal folds. The smaller vocal folds vibrate at a higher frequency, which results in a higher voice.
