The vocal chords in the larynx of women are smaller and tighter than they are in men. In children, they are about the same, but as boys go through puberty, their larynx changes and their vocal chords become longer, thicker, and looser. It happens in women too, but the change is not as dramatic as it is in men.

One reason, most females and young boys seem to have higher pitched voices, both when singing and when talking, than adult males, because most females and children have smaller larynxs and thus, shorter vocal cords that can vibrate faster, therefore the pitch is higher than the longer vocal cords present in adult males.

Generally speaking, since women are smaller than men, they also have shorter vocal cords. In the same way that a short string vibrates more rapidly than a long one, so short vocal cords vibrate more rapidly than long ones, producing a higher pitch.

Testosterone alters the voice box/larnyx (grows) and the larger 'parts' provide for lower frequency sound.
