PMID 37909540WHAT IT FOUND
A new Praat plugin called VoxMore was developed to generate detailed acoustic voice reports for teaching and clinical use.
It visualizes voice signals across time, frequency, and cepstral domains. No patient outcomes or diagnostic accuracy were tested.
Key findings
01VoxMore is a Praat plugin designed to generate acoustic reports containing images and numerical values for sustained vowel analysis.
02The plugin produces reports with oscillograms, Fourier spectra, spectrograms, and cepstral peak prominence measures, along with numerical results.
03The resource was demonstrated on a single voice sample from one dysphonic woman, but no comparative effectiveness or diagnostic validity data were reported.

What it does not show
The plugin was only demonstrated on a single voice sample from one patient, so its performance across different voice disorders and populations is unknown. The study did not test whether the plugin improves student learning or clinical decision-making compared to existing methods. The plugin is currently in an experimental phase and has only been tested at one university. No reliability or validity data were reported for the acoustic measures generated by the plugin.
Declared interests
The study was funded by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) - Brasil.
The easy way to misread this
Do not assume VoxMore is a validated diagnostic tool or that it improves clinical outcomes. The study only describes the software's development and shows one example report; it did not test whether the plugin helps therapists diagnose patients or teach students more effectively than current methods.
