Question

how does vocal cords works?​

Answer 1

When you breathe, the vocal folds are open to allow air to flow from your upper airway into your trachea and lungs. When you want to speak, you close your vocal folds and begin to exhale, causing an increase in pressure that starts them vibrating (cyclic opening and closing).
