Electrolarynxes are Speech Technologies devices that replace the sound-vibrating capabilities of the larynx. The devices usually resemble a small hand-held tube that the user operates with one hand. The device is put against the tissue of the throat or under the chin and the user engages the vibrator on the device. The vibrations the device generates are then carried over to the inside of the oral cavity. The user can then use the rest of the vocal tract to shape the sound and speak.

This allows people who have lost either a part or the entire larynx due to cancer to be able to produce speech and to communicate again.
