The vocal chords

The vocal folds, also known popularly as vocal cords, are composed of twin infoldings of mucous membrane stretched horizontally across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.
Open during inhalation, closed when holding one's breath, and held apart just a tiny bit for speech or singing; the folds are controlled via the vagus nerve. They are white because of scant blood circulation.

The ORGAN involved is the lungs. Technically, vocal chords or not organs.
