Electrolarynx

A widely adapted form of laryngectomee speech is transcervical electrolaryngeal speech. A transcervical electrolarynx works by the user placing the vibrating diaphragm of the electrolarynx against his neck, the mechanical energy of the diaphragm is transmitted through the neck, exciting the air in the vocal tract; this excited air can be formed by the lips and mouth to yield speech. The limitations of modern devices are that they are cumbersome and unable to produce speech as natural sounding as human speech.
