Summary
This study introduces a new computerised method to assess functional dysphonia by analyzing phonetograms. This approach quantifies voice disorder severity, aiding in diagnosis.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Acoustic Analysis
Context:
- Functional dysphonia affects numerous individuals, necessitating objective diagnostic tools.
- Current clinical ratings of voice disorders can be subjective.
- Phonetography offers a quantitative measure of voice production.
Purpose:
- To develop and validate a computerised method for assessing functional dysphonia using phonetogram parameters.
- To correlate objective phonetogram measurements with subjective clinical ratings.
- To differentiate between hypofunctional and hyperfunctional voice components.
Summary:
- 160 subjects with functional dysphonia underwent clinical rating and phonetogram analysis.
- Phonetograms were mathematically modeled using ellipses to extract quantitative parameters.
- A linear combination of these parameters generated a 'calculated assessment' to predict the clinical rating.
- Distinct calculation methods were required for male/female singers and non-singers.
Impact:
- This computerised phonetogram evaluation provides an objective measure for diagnosing functional dysphonia.
- The method allows for the graduation of voice disorders based on hypofunctional or hyperfunctional components.
- It serves as a potential supplementary diagnostic tool in clinical practice.
