Explanation
Both the assertion and the reason are correct, and the reason perfectly explains the assertion. The pitch and quality of the human voice are primarily determined by the vocal cords located in the larynx. In adult men, the vocal cords are typically longer (approx. 17–25 mm) and thicker, which causes them to vibrate at a lower frequency, producing a deeper voice. In women, the vocal cords are shorter (approx. 12.5–17.5 mm) and thinner, leading to higher-frequency vibrations and a higher-pitched voice. This physiological difference in the dimensions of the vocal cords is the fundamental reason why the voices of men and women sound distinct.
