Abstract
This work aims to detect vocal disorders related to vocal nodule, Reinke’s edema and neurological pathologies through multiband cepstral measures of the sustained vowel/a/. Detection is performed between pairs of study groups and multiband analysis is accomplished using the Wavelet transform. For each pair of groups, a parameters selection is performed. Statistics of the selected parameters are used as input for four classifiers with leave-one-out cross validation. Classification accuracies equal or greater than 96.70% are obtained for 6pairs of study groups while only 74.20% is achieved for the Edema/Nodule pair
