Respiratory Diseases like Chronic obstructive pulmonary disease (COPD), Asthma, Pneumonia, and Tuberculosis (TB) are emerging as major health threats for many people across the globe. Hence early diagnosis and recovery monitoring of these diseases is obligatory. Cough is found to be the best symptom for the diagnosis of Respiratory Diseases. It has vital information regarding the disease. Cough is a reflex, with a deep inspiration, glottal closure, and an explosive expiration followed by a sound. The objective is to study and analyze cough characteristics and see how they differ among different diseases. This analysis helps in building applications like digital health advisory for Respiratory Diseases. We identified the important characteristics like Duration, Intensity, Type of cough and Frequency of coughs which will vary among the diseases. This paper presents the approach to be followed in deriving these characteristics and provides detailed analysis on how these characteristics are varying and presents results based on data collected covering important parameters like accuracy, specificity and sensitivity. Hence, we can conclude that the proposed methodology is an essential tool for respiratory diseases diagnosis in timely manner.
