Summary
A new multi-parameter voice analysis protocol accurately reflects perceptual assessments. This objective method, using maximal phonatory time (MPT), jitter, normalized noise energy (NNE), harmonic-to-noise ratio (HNR), and shimmer, aids in diagnosing dysphonia.
Area of Science:
- Speech Science
- Otolaryngology
- Acoustic Analysis
Context:
- Dysphonia diagnosis often relies on subjective perceptual voice analysis.
- Objective acoustic measures provide quantitative data but require robust interpretation.
- Developing a comprehensive objective protocol is crucial for consistent dysphonia assessment.
Purpose:
- To develop a multi-parametric protocol for objective and quantitative voice evaluation.
- To investigate the correlation between the developed objective protocol and perceptual voice analysis.
Summary:
- A novel five-parameter protocol (maximal phonatory time, jitter, normalized noise energy, harmonic-to-noise ratio, shimmer) was developed using discriminant analysis.
- This objective protocol demonstrated a 79.8% concordance with jury-based perceptual classification of voice disorders.
- The study included 83 women with dysphonia and 40 healthy women, analyzing sustained /a/ vowel recordings.
Impact:
- Establishes a reliable, multi-parameter objective method for voice assessment.
- Enhances the accuracy and consistency of dysphonia diagnosis.
- Provides a quantitative tool to complement subjective perceptual evaluations in clinical settings.
