Background: As rapid growth of respiratory diseases is witnessed around the world; medical research field has gained interest in integrating audio signal analysis-based technique which aids timely diagnosis of respiratory ailments effortlessly in early stages of a respiratory dysfunction. Method: Our tool [1] distinguishes adventitious respiratory sounds using Linear Predictive Cepstral Coefficient (LPCC)-based feature [2] along with a Multi-Layer Perceptron (MLP)-based classifier. Results: When we applied our model on the largest publicly available ICBHI17 dataset [2] of size 6800+ clips we obtained the highest possible accuracy of 99.22% with an AUC value of 0.9993. Conclusion: Our results (accuracy 99.22%) outperformed established works in literature and other machine learning techniques and in future we will extend our research to identify nature and severity of infection just from the breath sounds.
