A voice box, known as a larynx, was a component of Human anatomy situated in the throat. Each Human possessed a single larynx. The larynx could be damaged during a Force choke, potentially leading to death.
A surgical implant near the larynx was part of Crozo Industrial Products' At-cyb husher mike. This vocalizer implant conveyed subvocalized messages by interpreting the motions of the jaw, tongue, and vocal cords.
