Laboratory projects in tactile aids to lipreading.

C L De Filippo

    Ear and Hearing
    |July 1, 1984
    PubMed
    Summary

    Tactile aids can improve lipreading for deaf adults, offering a 40% gain in syllable identification. However, gains were minimal for untrained words, and neither feature nor spectral coding proved superior.

    Area of Science:

    • Audiology
    • Human-Computer Interaction
    • Assistive Technology

    Background:

    • Lipreading (speechreading) is a crucial skill for individuals with hearing loss.
    • Existing assistive technologies for lipreading often have limitations.
    • The development of tactile aids aims to supplement visual speech cues.

    Purpose of the Study:

    • To investigate the effectiveness of different tactile aids in enhancing lipreading performance.
    • To evaluate tactile displays encoding speech features (resonance, envelope, source) and spectral information.
    • To compare the efficacy of feature-based versus spectral-based tactile coding for lipreading support.

    Main Methods:

    • Four studies involving artificially-deafened and congenitally deaf adults.
    • Development and testing of a speech feature tactile aid with fingertip vibrators.
    • Evaluation of tactile sensation quality as a cue to spectral information using electrical and vibratory stimulation on hand and torso.
    • Use of syllable identification and connected speech tracking techniques.

    Main Results:

    • A speech feature aid resulted in a 40% average gain in syllable identification for trained deaf adults compared to lipreading alone.
    • Minimal gains were observed for untrained words with the feature aid.
    • Tactile coding of spectral information yielded variable increments over unaided lipreading and simple vibrator aids.
    • Neither the feature nor the spectral code demonstrated superiority in aiding lipreading.
    • Displays emphasizing quality changes appeared more efficient for training than spatial displays.

    Conclusions:

    • Tactile aids show potential for improving specific aspects of lipreading, particularly syllable identification.
    • The design of tactile displays and training methods significantly impacts effectiveness.
    • Further research is needed to optimize tactile coding strategies and training protocols for broader lipreading enhancement.
