Voice profiling is already making its way onto the radar of marketers at major companies — Spotify patented technology to read listeners’ emotions through their voice. However, a more immediate compelling use case of voice analysis technology is for healthcare. Wearables like Fitbit and Apple Watch are already widely used to glean health insights related to heart rate and fitness, but voice technology can unearth hidden abnormalities rooted in our voices. University of Washington researchers found that assistants may be able to identify those having heart attacks, and Mayo Clinic explored how high blood pressure can be detected from voice recordings. In the future, voice has the potential to catch life-threatening conditions before they become deadly. But with heightened concerns around what exactly our assistants listen to, voice biometric providers must evaluate how they can instill trust in consumers.
