Samples are grouped based on healthy status and diseases
The duration of these vowel samples was 3 s for healthy voices and 1 s for pathological voices. A 25 or 50 kHz sampling rate was employed to pathological and healthy voices, respectively. All the files were downsampled to 25 kHz and a single 400 ms frame of analysis was considered for each signal
