| dc.description.abstract | This paper presents a comparison between the spectral analysis of the voices from patients diagnosed with bulbar amyotrophic lateral sclerosis (ALS) and healthy speakers. The main objective is to understand how this disease affects the voice and, consequently, the spectrum of the patients' voices. The spectrum is analysed in three energy bands, where energy peaks are estimated and the tilt between these bands is computed. The results obtained allow to conclude that the subjects diagnosed with bulbar ALS present significant differences in the mean values and variances of the energy peaks in this bands compared to the healthy speakers and, consequently, in the tilt between bands. The method presented has 85% classification rate without resorting to highly complex classifiers. | pt_PT |
