What Your Cough Says
Different sicknesses make different kinds of coughs. A wet cough sounds different from a dry one. A wheezy cough means something else again.
Apps can listen through a phone microphone and label the cough. The AI is trained on millions of cough recordings. It's not a doctor, but it gives a helpful first guess.
When this is helpful
Tracking a long cough day-by-day
Helping the doctor at telehealth visits
Catching night coughs grownups didn't hear
Showing patterns over a week
The big idea: AI cough listeners give doctors a head start — but you still need a real doctor to figure out what's wrong.
