A battery-powered, speech-assistive device designed to be used by a person who has had their larynx removed (laryngectomy) to assist them in the reproduction of sounds similar to those produced by the vocal cords in normal speech. It is an externally-applied electromechanical device (also known as a neck-type artificial larynx) with a plastic or metal probe that generates a sound (i.e., tone); when the probe is held against the tissues of the neck (or cheek) the tone is transmitted to the mouth through the oropharynx. The appropriate movement of the lips, tongue, teeth, and jaw converts the tone into meaningful speech (i.e., modulates the tone).
