Analyzing Acoustic Properties of the Vowel "a" Collected Via Mobile Phone From Individuals Diagnosed With Chronic Obstructive Pulmonary Disease and Health Control Groups
The Study aims to identify the changes in voice caused by Chronic Obstructive Pulmonary Disease (COPD) statistically for identifying the potential digital voice biomarkers.
1058 voice recordings collected via mobile phones over time in form of the Swedish utterance of vowel "a" will be analysed using vowel quadrilateral space and the Mann-Whitney U test.
The significance threshold p-value will be set to 0.05, and vocal features consisting of 101 base line acoustic features and MFCC features will be analysed between the COPD and HC groups. The most significant features that remain under the significance threshold will be reported.
