This study validates an objective tool for assessing dysphonia using airflow and sound measurements. The findings show this method can effectively distinguish between normal and pathological voices.

Area of Science:

  • Speech-language pathology
  • Acoustic analysis
  • Biomedical engineering

Context:

  • Dysphonia, a voice disorder, often requires subjective evaluation.
  • Objective acoustic and aerodynamic measures offer potential for more reliable assessment.
  • Developing validated tools is crucial for clinical practice.

Purpose:

  • To validate an objective aid for evaluating dysphonia using acoustic and aerodynamic measurements.
  • To assess the efficacy of analyzing exhaled airflow, fundamental frequency, and sound pressure level.
  • To determine if principal component analysis can differentiate vocal pathologies.

Summary:

  • Objective measurements of exhaled airflow, fundamental frequency, and sound pressure level were recorded from 51 dysphonic and 15 normal subjects during a sustained vowel phonation.

  • Key parameters analyzed included mean, standard deviation, and coefficient of variation, along with 2-second exhaled airflow volume.
  • Principal component analysis successfully distinguished between normal and pathological vocal evaluations.

    • Impact:

    • This study provides evidence for an objective aid in the clinical evaluation of dysphonia.
    • The validated tool can enhance the accuracy and consistency of voice disorder assessment.
    • Objective measures may lead to improved diagnosis and treatment planning for individuals with dysphonia.
