In 13th International Joint Conference on Biomedical Engineering Systems and Technologies. Malta. ISSN 2184-4305. 4, p. 288-295.2184-4305http://hdl.handle.net/10198/26895The work consists in a classification problem of four classes of vocal pathologies using one Deep Neural Network. Three groups of features extracted from speech of subjects with Dysphonia, Vocal Fold Paralysis, Laryngitis Chronica and controls were experimented. The best group of features are related with the source: relative jitter, relative shimmer, and HNR. A Deep Neural Network architecture with two levels were experimented. The first level consists in 7 estimators and second level a decision maker. In second level of the Deep Neural Network an accuracy of 39,5% is reached for a diagnosis among the 4 classes under analysis.engVocal acoustic analysisLeave-one-outDeep neural networkArchitecture of deep-NNDysphoniaVocal fold paralysisLaryngitis chronicaconference paper10.5220/0009148802880295
