Vocal Feature Analysis Algorithm

Sponsored by Soniphi in collaboration with UserWise

This is an observational, prospective, non-randomized, non-significant risk study collecting voice recordings from subjects who are being tested for COVID-19 by laboratory analysis of specimens obtained by nasal or naso-pharyngeal (NP) swab.

Patients record their voices through an app on their mobile phone. Patients and health care providers will be blinded to the swab test results during Phase 2 of the study.


Coronavirus disease 2019 (COVID-19) is a respiratory illness that can spread from person to person. The virus that causes COVID-19 is a novel coronavirus that was first identified during an investigation into an outbreak in Wuhan, China.
