Summary
This study developed an objective voice disorder evaluation protocol using multi-parameter analysis. The new method shows good concordance with expert perceptual evaluation, enabling quantitative voice assessment.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Acoustic Analysis
Context:
- Voice disorders significantly impact quality of life.
- Current perceptual evaluations are subjective.
- Objective, quantitative measures are needed for accurate diagnosis and treatment monitoring.
Purpose:
- To establish an objective multi-parameters evaluation protocol for voice disorders.
- To explore the concordance between objective analysis and perceptual evaluation.
- To enable objectification and quantification of voice disorder assessment.
Summary:
- Objective voice parameters (jitter, shimmer, F0SD, NNE, HNR, MPT) were analyzed in 271 dysphonia patients and 69 controls.
- These parameters showed high correlation with expert perceptual grading (GRBAS scale).
- Established male and female-specific protocols demonstrated good concordance (81.6-83.2%) with perceptual evaluations.
Impact:
- Provides a reliable, objective, and quantitative method for voice disorder evaluation.
- Enhances diagnostic accuracy and treatment efficacy for voice pathologies.
- Facilitates standardized voice assessment across clinical settings.

01:25Factors Affecting Perception
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

01:13Multiple Comparison Tests
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
