Quick Fixes to Bring Back Damaged Voices The voice box, or larynx, houses two elastic vocal cords atop the windpipe. The cords close when people swallow, protecting the airway. They open when people breathe. And they come together and vibrate when people speak or sing. Paralysis or weakness of a vocal cord can occur when the nerve that supplies it is damaged. This nerve, the recurrent laryngeal nerve, is famously circuitous, looping down into the chest before heading back up to the voice box.
