Cough analysis is an important area in the clinical diagnosis of various respiratory illnesses. Cough is the body's inundate mechanism to clear the throat and lungs of foreign material. It presents a great opportunity for the initial assessment of potential patients infected by COVID-19 which is a new virus. With symptoms like other respiratory illnesses, dry cough, fever and fatigue, it is challenging to classify probable Covid infection with no Covid data available yet. However, we propose a CNN based audio classifier [1] using the open cough dataset. The dataset is labeled manually into cough categories with final labeling into Covid and Non-Covid classes. The two approaches proposed in this paper are based on mfcc features and spectrogram images as input to CNN network. MFCC approach produced 70.58% test accuracy with 81% sensitivity and is better than the spectrogram-based approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
