    Profoundly deaf children can perceive speech through vibrations, aiding their learning. This vibratory speech information supplements lipreading and supports speech training for enhanced communication.

    Area of Science:

    • Audiology
    • Speech-Language Pathology
    • Educational Psychology

    Background:

    • Profoundly deaf children often perceive amplified speech as tactile vibrations rather than auditory input.
    • Vibratory transducers are utilized in classrooms to offer supplementary speech information to deaf children.
    • Effective presentation of vibratory stimuli is crucial for perceptual learning in deaf individuals.

    Purpose of the Study:

    • To investigate the nature of speech cues perceivable through vibration.
    • To explore the potential of vibratory perception as a supplementary tool for deaf children.
    • To inform educators on optimizing vibratory speech input for learning.

    Main Methods:

    • Describing various speech cues available via vibratory sense, including syllable count, rate, stress, and pauses.

  • Utilizing an optical analog (storage oscilloscope tracings) to visualize vibratory speech information.
  • Assessing the ability of deaf children to recognize and identify vibratory speech patterns.

    • Main Results:

    • Vibratory perception provides essential gross time-intensity information of speech.
    • Deaf children demonstrated capability in closed-set recognition tasks using vibratory input.
    • Learners could identify general characteristics of vibratory speech patterns.

    Conclusions:

    • Vibratory perception offers valuable speech information, particularly temporal and intensity aspects.
    • While limited for standalone communication, vibratory input enhances lipreading and aids speech training.
    • Optimizing the use of vibratory transducers can significantly benefit profoundly deaf learners.
