Evaluation of a tactile vocoder for work recognition.

P L Brooks, B J Frost

    The Journal of the Acoustical Society of America
    |July 1, 1983
    PubMed
    Summary

    Individuals can learn to identify spoken words using a tactile vocoder, a device that translates sound into tactile sensations. This technology shows promise for enhancing communication, particularly for those with hearing impairments.

    Area of Science:

    • Neuroscience
    • Auditory Neuroscience
    • Sensory Substitution

    Background:

    • The human auditory system processes complex acoustic information.
    • Sensory substitution aims to convey information normally perceived by one sense through another.
    • Tactile displays offer a potential channel for sensory substitution.

    Purpose of the Study:

    • To investigate the efficacy of a tactile vocoder for word identification.
    • To assess the learning rate and capabilities of subjects using tactile speech perception.
    • To determine if phonetic features can be reliably conveyed through tactile stimulation.

    Main Methods:

    • A 16-channel tactile vocoder was developed, converting speech frequencies (200-8000 Hz) into tactile stimuli on the forearm.
    • Subjects underwent extensive training with the tactile vocoder using spoken words.
    • Learning progress was quantified by the number of words identified correctly over training hours.

    Main Results:

    • One subject learned 70 words in 40.5 hours; another learned 150 words in 55 hours.
    • Improved word identification was observed with increased training experience.
    • Phonetic features like voicing, nasality, and frication were reliably recognized.
    • Rapid generalization of word-learning to unfamiliar speakers occurred.

    Conclusions:

    • A tactile vocoder enables rapid learning of spoken words through tactile perception.
    • This technology can effectively convey crucial phonetic information, complementing lipreading.
    • The tactile vocoder demonstrates significant potential as an assistive communication device.
