Sex Differences
Men and women have different vocal fold sizes. Adult male voices are usually lower pitched and have larger folds. The male vocal folds are between 17.5 mm and 25 mm (approx 0.75" to 1.0") in length.
The female vocal folds are between 12.5 mm and 17.5 mm (approx 0.5" to 0.75") in length.
Folds are pearly white in color - more white in women than in men.
The difference in vocal fold size between men and women causes a difference in vocal pitch. Additionally, genetic factors cause variations between members of the same sex, with men's and women's voices being categorized into types.

Famous quotes containing the word differences:
“I don’t know what immutable differences exist between men and women apart from differences in their genitals; perhaps there are some other unchangeable differences; probably there are a number of irrelevant differences. But it is clear that until social expectations for men and women are equal, until we provide equal respect for both men and women, our answers to this question will simply reflect our prejudices.”
—Naomi Weisstein (b. 1939)
