Deaf and hearing subjects were asked to identify the stress pattern in a short sentence from the variation in voice fundamental frequency (F0) when presented aurally (for hearing subjects) and when transformed into vibrotactile pulse frequency (for both groups). Various transformations from F0 to pulse frequency were tested. The results indicated that a one- or two-octave reduction of F0 to vibrotactile frequency (transmitting every second or third glottal pulse) might result in a significant ability to discriminate the intonation patterns associated with moderate-to-strong patterns of sentence stress in English, for a wide range of speakers. However, the reception of the details of the intonation pattern may be masked by an apparent temporal indeterminancy of about 125 ms noted in the perception of variations in vibrotactile frequency. The results also offered some limited support for our previous hypothesis that there is a natural association between auditory pitch and perceived vibrotactile frequency. [Work supported by NIH.]
