Anup Kumar Singh, New Delhi. Respiratory screening medical AI tool “Swasa” is the center of discussion at the India AI Impact Summit 2026 in the national capital. It analyzes the sound of cough to detect early symptoms of lung diseases.
It is being seen as a potential technological tool to overcome the shortage of resources in the healthcare system in the country. It is a non-invasive and easily accessible screening tool, eliminating the need for traditional equipment such as spirometers.
How does this work?
Swasa records cough sounds using a smartphone's microphone and, using machine learning and digital signal processing, uses the cough as a "biomarker" to detect lung health. This creates a Lung Health Index score, which the doctor or healthcare professional uses for further investigation.

This shows whether the lungs are functioning normally or abnormally. SWASA can identify patterns of diseases such as asthma, chronic obstructive pulmonary disease, interstitial lung disease and bronchitis. It also detects the risk level by combining symptoms, temperature and oxygen saturation data with the sound of cough. Swasa was developed by Salsit Technologies in Hyderabad.
Many scientific studies have been published on SWASA. The test was evaluated for screening the risk of pulmonary tuberculosis (lung disease) in a 2023 study. In the study, it was evaluated on the data of 567 people, in which the average sensitivity was more than 90 percent and accuracy was about 87 percent. This research was published in Scientific Reports Medical Journal.
In another study, it was tested on 355 people, in which it was found that it is 97 percent sensitive and capable of differentiating between normal and abnormal lung conditions. It has also been successfully used and tested in primary and rural health centres.
Certification and Health Standards
Swasa, known as Software-as-Medical-Device, has received license as a Class B medical device from the Central Drugs Standard Control Organization (CDSCO) in India. It also has certification for data security and quality standards as per international standards for health data security and device quality.
The unique feature of Swasa is that it works without any special training or expensive equipment. Experts say this technology can speed up the identification of early symptoms and guide health workers to further investigation and treatment.
It is cheap and fast, giving instant reports in just 10 to 15 seconds. It can be used on smartphone, tablet or laptop. It uses very low bandwidth and does not require any expensive equipment, making it ideal for rural and remote areas.
