Adding tactile information significantly improves speech perception for both hearing and hearing-impaired individuals. This electrotactile aid provides crucial high-frequency cues, especially beneficial for those with severe to profound hearing loss.

Area of Science:

  • Audiology
  • Neuroscience
  • Biomedical Engineering

Background:

  • Speech perception relies on auditory and visual cues.
  • Hearing loss can impede access to critical speech information, particularly high-frequency sounds.
  • Tactile sensory substitution offers a potential alternative or supplement for auditory information.

Purpose of the Study:

  • To investigate the effectiveness of combining tactile input with auditory and/or visual information for speech perception.
  • To evaluate the contribution of a multichannel electrotactile speech processor to speech discrimination.
  • To determine the utility of tactile aids for individuals with varying degrees of hearing impairment.

Main Methods:

  • Three studies were conducted involving normally hearing and hearing-impaired adults.

  • Subjects received speech stimuli through combinations of audition (filtered), lipreading, and tactile input via an electrotactile speech processor.
  • Speech perception metrics, including phoneme/word discrimination and speechtracking rate, were analyzed.

    • Main Results:

    • Tactile information significantly enhanced speech perception scores (phoneme, word discrimination) in normally hearing individuals when added to audition or audition plus lipreading.
    • The electrotactile aid effectively conveyed acoustic features like duration, vowel formants (F1, F2), and consonant manner of articulation.
    • Improvements in speech perception and speechtracking rate were observed with tactile augmentation across various auditory filter cutoff frequencies.
    • For hearing-impaired participants, tactile aid benefits were inversely related to residual hearing, suggesting greater utility for those with severe to profound loss.

    Conclusions:

    • Multichannel electrotactile stimulation is a viable method for delivering speech-relevant information through the tactile modality.
    • This technology can significantly enhance speech perception, particularly for individuals with limited or no residual hearing.
    • Electrotactile aids offer a promising avenue for improving communication accessibility for the severely to profoundly hearing impaired.
