Google's HeAR Tool Revolutionizes Health Diagnosis with Sound-Based Technology

Google scientists have developed a machine-learning tool called Health Acoustic Representations (HeAR) that can detect and monitor health conditions by analyzing sounds such as coughing and breathing. Trained on millions of audio clips of human sounds, HeAR shows promise in diagnosing diseases like COVID-19 and tuberculosis, as well as assessing lung function. Unlike traditional supervised learning methods, the researchers used self-supervised learning with unlabelled data. By converting over 300 million sound clips into visual representations, the model can be adapted …
