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.
