A mechanical larynx is a medical device used to produce clearer
speech by those who have lost their original
voicebox, usually due to
cancer of the larynx. It is also referred to as a 'throat back'. The most common device is the electrolarynx which is handheld, battery operated and placed under the
mandible producing vibration to allow speech. Along with developing
esophageal voice or undergoing a surgical procedure, the mechanical larynx serves as a mode of speech recovery for
postlaryngectomy patients.
