The Google HeAR Project (Health Acoustic Representations) is an initiative that uses AI-powered diagnostics to detect diseases by analyzing sounds like coughing and sneezing. It listens to body sounds, processes them using machine learning, and compares them to a database of known sound patterns associated with specific illnesses. This system is designed to offer non-invasive disease detection, helping diagnose conditions such as asthma, pneumonia, and even COVID-19.
