ABSTRACT:
An electronic artificial larynx supported and operated without the use of an operator's hands. The artificial larynx includes an electrical circuit having a signal generator and a tone generator. The tone generator is attached to and supported by a pair of eyeglasses worn by the operator. A switch for opening and closing the electrical circuit is attached to a portion of the operator's body and is actuated by movement of one of the operator's limbs relative to his torso. In a preferred embodiment, the switch is attached to an arm band and is actuated by movement of an operator's arm toward his torso.
