Abstract
An intra-oral artificial larynx includes a signal generator encapsulated within a custom-molded prosthetic means for mounting the larynx within the intra-oral cavity, as well as a speaker and tongue activatable switch for enabling the signal generator and the speaker. A compartment is molded in the custom-molded prosthetic means for receiving a power source, the power source being mounted on a carrier removably mounted in the compartment for powering the signal generator and speaker. The power source carrier is slidably received within the compartment and includes a means for isolating the compartment from saliva in the intra-oral cavity.
