An electrolarynx is a handheld, battery-powered electronic device that produces a vibrating, artificial sound used to speak after a laryngectomy (removal of the voice box) or other laryngeal conditions. The user presses the vibrating head of the device against their neck or under their chin, and the sound travels through the tissues to the mouth.
How it Works
Vibration: The device has a vibrating head that creates a buzzing or humming sound.
Transmission: This vibration is transmitted through the skin and tissue of the neck into the vocal tract.
Articulation: The user then articulates this artificial sound into speech using their oral structures, similar to how they would normally speak.
Purpose
Voice Restoration:
It is a method of voice rehabilitation, allowing individuals who have lost their natural voice to communicate.
