Abstract
A wearable tactile sensory aid which presents a vibratory signal representative of voice pitch and intonation patterns to the skin. The vibratory signal consists of a constant amplitude square wave having a frequency equal to, or some fraction of, the fundamental frequency of the speech input. The vibratory signal is applied as a tactile stimulus, and is displaced along a linear array of transducers in contact with the skin in proportion to the logarithm of the fundamental frequency. Accordingly, the wearable tactile display encodes the fundamental frequency to provide both frequency of actuation and spatial indications thereof.
