Smartphone App Uses Voice To Predict Asthma, COPD Flare-Ups

FRIDAY, July 10, 2026 (HealthDay News) — Voice changes measured by a smartphone app can send up a red flag for people with asthma or COPD, warning them of an oncoming symptom flare-up, a new study says.

In the future, daily voice checks using such an app might be used to monitor for signs of an asthma or COPD exacerbation, researchers write in a study published recently in ERJ Open Research.
