Abstract
Periodic and transient pulses of pressure, correlated with specific speech sounds, were applied to the palm of the hand by a special transducer. The intuitive responses of subjects indicated the stimuli as “feeling like” certain vowels, stops, and fricatives, and the electrical analog of this taction parallelled the electrical analog of a model of the ear into which the spoken stimuli were fed. The ease of communication when using this synthetically produced “tactile speech” contributes strongly to a theory that tactile-auditory coupling in the central nervous system may exist. Specific waveform details and test results are described. [Work sponsored by the Aeronautical Systems Division, Air Force Systems Command, U. S. Air Force.]
