Respiratory illnesses such as RSV (respiratory syncytial virus), influenza and COVID-19 are often caught late. By then they have already spread through crowded places like schools, airports and hospitals.

What they work on

  1. Assess the translation potential of a voice-based pre-screening tool for RSV, influenza and COVID-19 through I-Corps interviews and first-hand study of the healthcare industry.
  2. Develop machine learning algorithms that detect real-time changes from a user's own baseline voice, heart rate and temperature and relate them to clinically observed respiratory illness patterns.
  3. Enable secure, scalable deployment on smartphones, wearables and smart speakers using edge AI (on-device computing) and signal processing for continuous, passive monitoring.

More about the research

A voice can change subtly when a person falls ill, and phones, smartwatches and smart speakers already capture voice and body signals. The question is whether these everyday signals could flag an infection early.

Why it matters

Earlier warning of respiratory infections could let people stay home or seek care before illness worsens or spreads. This may matter most in schools, airports and hospitals. Passive screening through phones and wearables could cut unnecessary clinic visits, speed up triage and support community-wide tracking of RSV, influenza and COVID-19. This could ease the strain on health systems and lower costs.
