$\huge\boxed{ \fcolorbox{blue}{yellow}{answer}} \:$

the voice box or larynx is the most important source of sound in human beings. To ligaments normally called vocal cords stretch across the larynx in such a way that there exist a narrow slit between them for the passage of air.

the forced air from the lungs through the slit makes the vocal cord to vibrate and produce sound. Muscles attached to the vocal cords may increase or decrease their pull on ligaments. This makes the vocal cords to be tight or loose, thick or thin. When the vocal cords are tight and thin, the voice of high frequency is produced. The loose and thick vocal cord produce a low frequency of sound.
