The data used in this study were gathered from 188 patients with PD (107 men and 81 women) with ages ranging from 33 to 87, at the Department of Neurology in Cerrahpaşa Faculty of Medicine, Istanbul University. The control group comprises 64 healthy individuals (23 men and 41 women) with ages between 41 and 82. During the data collection process, the microphone is set to 44.1 KHz, and following the physician's examination, the sustained phonation of the vowel /a/ was collected from each subject with three repetitions. |
