Area of Science:

  • Speech-Language Pathology
  • Otolaryngology
  • Biomedical Engineering

Background:

  • Voice disorders often require modifying voice production techniques.
  • Effective biofeedback methods are crucial for patient rehabilitation.

Purpose of the Study:

  • To describe Laryngeal Image Biofeedback (LIB) as a novel technique.
  • To assess the effectiveness of LIB as a learning tool for voice modification in patients with voice disorders.

Main Methods:

  • LIB technique development for visualizing vocal fold posture.
  • Assessment of LIB's efficacy in a cohort of 20 subjects.
  • Evaluation of vocal production modification through LIB.

Main Results:

  • LIB provides visual feedback on vocal fold posture.
  • The technique demonstrated effectiveness as a learning tool.
  • Subjects showed ability to modify vocal production using LIB.

Conclusions:

  • Laryngeal Image Biofeedback (LIB) is a promising technique for voice therapy.
  • LIB facilitates patient learning and modification of vocal production.
  • Further research should explore LIB's application in diverse voice disorders.
