Advances in Clinical Voice Quality Analysis with VOXplot

Background: The assessment of voice quality can be evaluated perceptually with standard clinical practice, also including acoustic evaluation digital recordings to validate and further interpret perceptual judgments. goal the present study was determine strongest parameters for perceived hoarseness breathiness when analyzing sustained vowel [a:] using a new tool, VOXplot software. Methods: A total 218 samples individuals without disorders were applied analyses. Overall, 13 single included validity aspects in relation perceptions breathiness. Results: Four measures could clearly associated or For hoarseness, harmonics-to-noise ratio (HNR) pitch perturbation quotient smoothing factor five periods (PPQ5), and, breathiness, smoothed cepstral peak prominence (CPPS) glottal-to-noise excitation (GNE) shown highly valid, significant difference being demonstrated each other aspects. Conclusions: Two measures, HNR PPQ5, both strongly able discriminate from good confidence. CPPS GNE,
