ABSTRACT:
A touch switch contacts on a unit housing are bridged by the fingers of a person's hand when holding the housing to trigger operation of a signal generating oscillator driving a transducer from which "voice" sound is generated and transmitted through a sound tube into the person's mouth for articulation of speech. The oscillator is operated at a low duty cycle for moderate battery consumption when the sound tube is extended from a retracted storage position within a recess formed in the housing.
