Artificial larynx
First Claim
1. An artificial speech tone generation device for use by post-laryngectomy patients comprising:
- (a) a tone frequency generation means arranged and constructed to provide a substantially natural sounding artificial human voice tone within a human oral cavity for modulation by oral anatomy and movement,(b) a control means for manual operation by a user thereof including a hand activated control incorporating simultaneous on-off, pitch and volume control by a single control means over a predetermined continuum of control combinations combining pitch and volume,(c) said tone frequency generation means being arranged and constructed for accommodation intraorally and said control means being arranged and constructed for operation in a hand of the user whereby a post-laryngectomy patient may effectively control volume and pitch of an artificial human voice tone in a more natural sounding combination than otherwise, and(d) in which the control means for manual operation and the tone frequency generation means are arranged and configured for intercommunication via spacially transmitted information carrying waveforms.

Abstract
An artificial larynx consists of (1) a first unit mounted in the mouth comprising a dental prosthesis, including a loud speaker, a power amplifier, a self-contained power source, plus a radio frequency receiver, and (2) a second unit held in the hand equipped with an input control device, self-contained power source, electronic circuitry and transmitter allowing the user to alter the frequency and volume produced by the unit in the mouth. The construction and components of the unit allows laryngectomees to speak with both a natural sound and a high degree of intelligibility. The unit preferably includes a system architecture including operational software which implements predetermined control of a fundamental repetition rate of voice pulses provided by the unit, to control the tonal quality of the sound, to include aspiration noise in the sound, to include pseudorandom variation of the fundamental repetition rate of the tonal pulse, includes diplophonic structure in such pulse and is able to simulate whispering.

15. An artificial speech tone generation device comprising:
-
(a) a tone frequency generation device arranged and constructed to provide a substantially natural sounding voice tone within a post laryngectomy patient'"'"'s oral cavity for modulation by mouth structures of said post laryngectomy patient including a battery means, a loud speaker, an electronic circuit which can detect spacially transmitted signals and convert them to electrical signals for powering the loud speaker, and acoustic structures allowing wound to reach the oral cavity while protecting the loud speaker from saliva and bacteria, (b) a control means for manual operation by the post laryngectomy patient including a hand activated control incorporating on-off means, plus pitch and volume control by a control means over a predetermined continuum of control combinations combining pitch and volume, (c) said control means comprising a combined microcontroller and computer software program, and (d) wherein an electromagnetic communication channel is used to transfer signals between the tone frequency generation device in the post laryngectomy patient'"'"'s oral cavity and the control means for manual operation. - View Dependent Claims (16, 17, 18, 19, 20)

21. An artificial larynx including an oral unit and a control unit:
-
(a) said oral unit comprising (i) prosthetic means for mounting an artificial larynx within a laryngectomy patient'"'"'s oral cavity; (ii) a power source mounted in association with said prosthetic means; (iii) an electronic circuit for receiving and deciphering signals sent from a control unit; (iv) a power amplifier; and (v) a loud speaker; (b) said control unit comprising; (i) a housing; (ii) a power source; (iii) an electronic circuit means; and (iv) a human interface device; such units being arranged and constructed for generating, transmitting and receiving under control of a laryngectomy patient acoustic tonal pulse representations of a human glottal pulse to produce natural sounding speech, such control being arranged and constructed to activate and deactivate such pulse, to control a fundamental repetition rate of such pulse and to control both independently and jointly sound amplitude. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
