Touch and vibration sensations accompanying the act of speakking providdide a series of typical afferent neurallal signals associated with speech. These sensations can be evoked at other locations on the body by electro-mechanical transducers. Substitute tactile sensations are subjectively acceptable in lieu of their real counterparts, and the tactile recognition of a speech-form is accomplished by association when artificial speech-taction is generated in the palmar surface of the hand. Palmar stimulation is effected with pulses of electrical energy transduced to mechanical form, which in turn produce epidermal strain analogous to the subjectives tactile sensations of speech. Real-time speech-taction is anticipated as a future reality through the use of an analoggog ear which will reeeduce the spoken wordrd to its primary elements of intelligibility and construct from them speech-compatible taction.
