Phonetograms, used for voice diagnosis, were quantitatively evaluated using a computer program. This program analyzed subareas of phonetograms, enabling better voice efficiency assessment and diagnostic comments.

Area of Science:

  • Laryngology
  • Speech Science
  • Medical Diagnostics

Background:

  • Phonetograms map sound pressure levels across vocal ranges, aiding voice status diagnosis.
  • Quantitative evaluation of phonetograms in medical practice remains limited.
  • Current methods often rely on reference phonetograms or single parameter extraction.

Purpose of the Study:

  • To develop a quantitative method for evaluating phonetograms in medical practice.
  • To assess voice efficiency and categorize voice types using phonetogram analysis.
  • To derive diagnostic comments from phonetogram data.

Main Methods:

  • A computer program was developed to analyze phonetograms.
  • Phonetograms were divided into subareas.
  • These subareas were approximated by elliptical patterns, and ellipse parameters were extracted.

Main Results:

  • The ellipse parameters derived from phonetogram subareas allowed for quantitative voice evaluation.
  • The method demonstrated potential in recognizing different voice categories.
  • Diagnostic comments could be generated based on the analyzed phonetogram data.

Conclusions:

  • The developed computer program offers a quantitative approach to phonetogram analysis.
  • This method enhances the diagnostic capabilities for voice disorders.
  • Ellipse parameter analysis of phonetograms shows promise for objective voice assessment.
