Developing accurate and inexpensive ways to diagnose diseases also remains a challenge, although several prominent companies such as Fedo, which uses selfies to assess certain vital signs, and Canary Speech, which uses the human voice to detect various cognitive and behavioral disorders (both of which have outstanding diagnostic performance), are making progress using new artificial intelligence tools. “The voice is the most complex motor function we produce in the body. It's very, very rich in information,” Canary co-founder and CEO Henry O'Connell said at conference in 2025. “If there is any defect, whether it is a cold or a progressive neurological disease, they all affect the ability of the central nervous system to control and create speech.”
The main benefit of digital health will be that patients will be able to learn more about their health and also take steps to avoid or better manage diseases. Companies like Oura (recognized for excellence in medical devices and wearables), which make wearable medical devices and telehealth organizations, continue to find new ways to inform people and connect with healthcare providers as patients demand the same transparency and depth of information they enjoy in other areas of their lives (such as retail and transportation) in how they manage their health.
