electric larynx

An electric larynx, also known as an artificial larynx, is a device used by individuals who have had their larynx removed due to cancer or trauma, a procedure called laryngectomy. This surgery alters breathing and communication, leaving the person unable to speak normally.12

The electric larynx acts as a substitute for the vocal cords. It's typically a small, handheld device containing batteries and a sound source. When held against the throat, it produces vibrations that travel through the neck tissues into the pharynx, allowing for audible and intelligible speech. Other models exist, including those that channel sound through a tube into the mouth or are integrated into dental plates. This technology helps laryngectomees regain their voice and communicate effectively.12
