Both clinicians and patients can benefit from these systems as they provide many advantages, compared to the invasive techniques. These systems can produce binary (healthy/pathological) or multiclass (healthy/selected pathologies) decisions. However, multiple disorders might exist in an individual's voice. Multilabel classification should be considered in such cases. By this time, only a single report is available on this topic, where hand-crafted features were used, and a data augmentation technique was utilized to overcome class imbalances. In this study, a similar experimental setup is followed to investigate the suitability of raw voice signals as inputs for multilabel classification. A deep learning model which consists of residual blocks and a novel gating mechanism is proposed. The gating mechanism weighs the channels of a residual block's output based on both its output and the previous layer's output. Using a SincNet filterbank that operates directly on the raw waveform as the initial layer, 0.99 accuracy and 0.98 F1 score were observed for natural /a/ vowels of Saarbruecken Voice Database with time domain augmentation to balance the class samples. On the other hand, reducing the number of augmented samples decreased the performance for both systems, indicating the need for a balanced dataset to avoid oversampling underrepresented classes. The proposed architecture performed consistently better than ResNet18 with deep connected attention, which verified the effectiveness of the proposed gating mechanism.eninfo:eu-repo/semantics/openAccessConvolutional neural networkdeep learningmultilabel classificationvoice pathologyArticle4Q2125237532WOS:001280878700006N/A
