Sonde is an AI voice technology and vocal biomarker startup that turns voice into a vital sign. They have identified 4,000 different vocal features. Sonde can detect the smallest changes in someone’s voice, which could indicate that the person is about to start or has already started to experience some type of a symptom. They already have products for depression, respiratory illness, sleepiness and hypertension detection and are working on many other diseases and disorders. 

Sonde Health isn’t claiming to be a diagnostic. What the AI-enabled software does is measure the risk of disease by identifying symptoms through vocal analytics. Sonde Health also has applications for behavioral health, respiratory health, and one that measures the risk of congestive heart failure (CHF). One great feature is that Sonde Health can be easily integrated into other apps through a self-serve API.
