Why does a person loses voice after a tracheotomy procedure is done?

A person loses their voice after a tracheotomy because the procedure creates an opening in the trachea, bypassing the vocal cords located in the larynx. Since air no longer flows through the vocal cords, they cannot vibrate to produce sound. Additionally, the direct airway created by the tracheotomy can disrupt normal respiratory functions and alter airflow, further affecting voice production.
