Abstract
An endotracheal tube (10) including, in addition to a primary ventilating channel (11), a secondary speaking channel (12). The speaking channel (12) contains an array of exit ports (16) for the introduction of a tone into the posterior oral pharynx (23) of the intubated patient. This tone is then conducted into the oral cavity (18) wherein it is articulated into speech by the patient. This substitute vocal sound is produced by a tone generating device (19) connected to and in air communication with the speaking channel (12) of the present invention.
