Automated Identification Of Respiratory Anomalies From Cough Acoustics Using Spectrogram-Driven Deep Learning
Keywords:
Cough acoustics, respiratory anomaly detection, spectrogram analysis, deep learningAbstract
Cough is a vital physiological reflex, often serving as a primary indicator of respiratory and other underlying health conditions [1]. Chronic cough, in particular, can significantly impair quality of life and signal persistent health issues such as asthma or chronic obstructive pulmonary disease (COPD) [2], [3]. Traditional diagnostic methods often rely on subjective patient reporting and time-consuming clinical assessments, which can lead to both over- and under-diagnosis [4]. This article presents a novel deep learning framework leveraging spectrograms of cough sounds for the automated identification of respiratory anomalies. By transforming raw audio signals into visual representations, we enable Convolutional Neural Networks (CNNs) to discern subtle patterns indicative of various pulmonary conditions. The proposed system demonstrates high accuracy in classifying anomalous cough sounds, offering a non-invasive, scalable, and potentially early detection tool to augment clinical diagnosis. Our findings underscore the significant potential of AI-driven acoustic analysis in revolutionizing respiratory healthcare diagnostics.
