Area of Science:

  • Otolaryngology
  • Speech Science
  • Medical Acoustics

Context:

  • Vocal cord polyps can significantly impair voice quality.
  • Objective assessment of voice changes post-surgery is crucial for patient management.
  • Previous methods for voice assessment may lack long-term objectivity.

Purpose:

  • To evaluate voice quality improvement after vocal cord polypectomy.
  • To introduce a computer-aided objective method for voice analysis.
  • To compare pre- and post-operative voice data with healthy controls.

Summary:

  • Fifteen patients undergoing vocal cord polypectomy had their voice quality assessed.
  • Recordings of vowels, words, and sentences in Hebrew were analyzed pre- and post-operation (1 and 3 months).
  • A computer program provided numerical and graphical data for Hebrew vowels, compared to normative data.

Impact:

  • Statistical analysis indicated a trend towards reduced differences between postoperative voice data and control data.
  • The computer-aided voice analysis method shows potential for systematic clinical application.
  • This objective, long-term assessment method can benefit patients with voice disorders, particularly professionals.
