The pitch of the voice of women is in general

The primary acoustic correlate of perceived pitch is the fundamental frequency (F0). Adult female voices typically have substantially higher F0 than adult male voices: typical female speaking F0 ranges around 165–255 Hz while typical male F0 ranges around 90–155 Hz, reflecting higher pitch for women [1]. Mean values reported in phonetic literature place males near ~120 Hz and females near ~200 Hz, confirming that women’s voices are generally higher in pitch than men’s [2]. This cross-gender difference arises largely from anatomical differences in larynx and vocal-fold size (secondary sexual characteristics), which lead to higher vibration rates (and thus higher pitch) in female speakers [2].
