Summary

The Tickle Talker, a wearable tactile device, showed potential to improve speech articulation in some children with profound hearing loss. This technology may offer a new avenue for speech training when traditional methods are insufficient.

Area of Science:

  • Audiology
  • Speech-Language Pathology
  • Assistive Technology

Background:

  • Severe and profound hearing impairment in children often leads to speech production difficulties.
  • Wearable tactile speech perception devices are proposed to aid speech monitoring and modification.
  • The efficacy of tactile feedback for improving articulation in pediatric hearing loss requires investigation.

Purpose of the Study:

  • To evaluate the articulation benefits of the multichannel electrotactile device, "Tickle Talker."
  • To determine if tactile input can enhance speech production accuracy in children with severe to profound hearing impairment.

Main Methods:

  • Six profoundly hearing-impaired children participated in the study.
  • Speech articulation was recorded and compared with and without the Tickle Talker device.

  • Articulation of vowels, consonants, and phonemes was assessed.

    • Main Results:

    • Three subjects demonstrated improvements in specific aspects of articulation.
    • One subject showed enhanced articulation of initial consonants and phonemes.
    • Another subject exhibited improvements in total vowels, consonants, and phonemes, including initial and medial sounds.

    Conclusions:

    • On-line tactile feedback from the Tickle Talker can benefit articulation accuracy in some children.
    • This electrotactile device may be a viable option for children who haven't responded to conventional speech training.
    • Further research is warranted to explore the full potential of tactile feedback devices in pediatric audiology.
