An electromechanical device that enables a laryngectomized person to speak.

Laryngectomized is the partial or total surgical removal of the larynx or organ of voice production containing the vocal cords.

When the electromechanical instrument is placed against the region of the laryngectomy (voice box surgery), a buzzing sound is produced, which is converted into simulated speech by the movements of the organs of articulation; such as the lips, tongue, and glottis.
