Summary
Objective voice analysis using VOXplot revealed significant acoustic differences in individuals with partial deafness (PD). This study compared VOXplot findings with the multi-dimensional voice program (MDVP) and perceptual assessments, highlighting voice abnormalities in PD patients.
Area of Science:
- Laryngology and Otology
- Speech and Hearing Sciences
- Acoustic Analysis of Voice
Background:
- Objective voice assessment aids in diagnosing voice changes and monitoring therapy progress.
- Limited literature exists on voice parameter changes in patients with partial deafness (PD).
- Previous studies on PD voice parameters primarily used the multi-dimensional voice program (MDVP).
Purpose of the Study:
- To perform an objective voice analysis in individuals with partial deafness using VOXplot.
- To assess the consistency of VOXplot results with the multi-dimensional voice program (MDVP).
- To evaluate the correlation between objective findings and perceptual voice assessment (GRBAS).
Main Methods:
- Voice samples (continuous speech and sustained vowels) were collected from 22 post-lingual PD individuals and 22 healthy controls.
- Acoustic analysis was conducted using both MDVP and VOXplot (version 2.0.0 Beta).
- Statistical analysis included t-tests, and perceptual assessment used the GRBAS scale.
Main Results:
- VOXplot identified 13 voice parameters with statistically significant differences in PD patients compared to controls.
- MDVP analysis indicated increased breathiness (e.g., NHR, APQ) and hoarseness (e.g., Jitt%, vF0) in PD patients.
- Correlations were observed between VOXplot parameters, MDVP parameters, and GRBAS perceptual scores.
Conclusions:
- Both VOXplot and MDVP detected voice abnormalities in individuals with partial deafness.
- The consistency between VOXplot and MDVP results was poor to moderate.
- Objective voice analysis findings correlated with subjective perceptual assessments in PD patients.

A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
