Abstract

Two experiments investigated deaf individuals' ability to distinguish speakers based on vibrotactile stimulation. Nineteen participants made same/different judgments on pairs of utterances presented to the lower back through voice coils embedded in a conforming chair. Discrimination of stimuli matched for F0, duration, and loudness was above chance for spoken sentences (Experiment 1) and vowel sounds (Experiment 2). Spectral measures of "different" stimulus pairs predicted their discriminability in both experiments. Beyond their application to assistive technology, these findings support the hypothesis that vibrotactile discrimination of spectral information involves cortical integration of filtered output from frequency-tuned skin receptors.
