Dynamic vocal analysis: vocal functionality evaluation.

PMID 37729254WHAT IT FOUND
This paper demonstrates how to use Dynamic Vocal Analysis (DVA) to assess voice functionality.
It shows examples of spectrograms for healthy and disordered voices but does not test whether the method improves patient outcomes or works better than other assessments.
What this paper is
This is a clinical demonstration of Dynamic Vocal Analysis (DVA), an auditory-perceptual and acoustic assessment strategy. It explains the method and shows spectrographic plates from a few individuals to illustrate how DVA looks in healthy and dysphonic voices. It does not report systematic results, outcomes, or evidence of efficacy, so there is no finding here to change your practice on.
The easy way to misread this
Do not interpret the illustrated spectrograms as proof that DVA is a validated or superior diagnostic tool. The paper presents examples to show how the assessment is performed, not data on its accuracy or clinical benefit.
