This study used a nasopharyngeal fiberscope for quantitative analysis to assess palate articulation in subjects. Computer analysis of specific sounds revealed velopharyngeal function insights.

Area of Science:

  • Speech-language pathology
  • Otolaryngology
  • Medical imaging

Background:

  • Palate articulation is crucial for speech clarity.
  • Quantitative analysis of velopharyngeal function aids in diagnosing speech disorders.
  • Nasopharyngeal fiberscopy offers a direct visualization method.

Purpose of the Study:

  • To quantitatively assess palate articulation using a nasopharyngeal fiberscope.
  • To evaluate velopharyngeal function through computer analysis of speech sounds.
  • To establish normative data for articulation analysis.

Main Methods:

  • Utilized a nasopharyngeal fiberscope (NPF) for image acquisition.
  • Performed quantitative analysis on 43 subjects with articulation issues and 60 normal subjects.

  • Calculated articulation parameters for sounds /a/, /s/, and /m/ using NPF images.

    • Main Results:

    • Demonstrated the feasibility of using NPF for quantitative articulation assessment.
    • Identified specific articulation patterns related to velopharyngeal dysfunction.
    • Provided computer-calculated metrics for speech sound production.

    Conclusions:

    • Nasopharyngeal fiberscopy combined with computer analysis is a viable tool for assessing palate articulation.
    • This method offers objective data for understanding velopharyngeal function.
    • Further research can refine this technique for clinical applications.
