Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a confirmatory study that seeks to examine whether respiratory-responsive vocal biomarkers have potential to respond to COVID-19 infection status and respiratory symptom severity. Patients with suspected COVID-19 and healthy controls will submit daily voice samples and symptom inventories on their personal smartphone devices for 14 days.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an observational study examining the potential to use voice analysis to aid in the identification of COVID-19 and as an aid to monitoring of respiratory symptoms of COVID-19. Patients with suspected COVID-19 and healthy controls will be enrolled and use their own smartphone device to provide daily voice samples and symptom inventories. This study seeks to confirm and extend findings from preliminary data from patients with asthma, COPD and cough that has indicated the potential of respiratory responsive vocal biomarkers (RRVB) to respond to respiratory diagnoses and symptom severity. The same RRVB will be examined to confirm whether this potential generalizes to respiratory symptoms associated with COVID-19

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

COVID-19 positive

Patients with suspected COVID-19 based on presence of at least one newly emerged relevant symptom that has emerged at most 10 days prior to enrollment. COVID-19 positive status is confirmed by diagnostic testing and clinical diagnosis.

Smartphone-based voice and self-reported symptom collection

Intervention Type OTHER

Voice samples and COVID-19 symptom inventories will be collected on participant smartphone devices. No outcomes or feedback is provided on acquired data during trial conduct but will be used for confirmatory data analysis post study

COVID-19 negative, symptomatic

Patients with suspected COVID-19 based on presence of at least one newly emerged relevant symptom that has emerged at most 10 days prior to enrollment. COVID-19 negative status is confirmed by diagnostic testing and clinical diagnosis.

Smartphone-based voice and self-reported symptom collection

Intervention Type OTHER

Voice samples and COVID-19 symptom inventories will be collected on participant smartphone devices. No outcomes or feedback is provided on acquired data during trial conduct but will be used for confirmatory data analysis post study

Normal Healthy Volunteers

Asymptomatic healthy participants recruited from hospital staff or co-living family members, or co-living family member of a COVID-19 positive study participant.

Smartphone-based voice and self-reported symptom collection

Intervention Type OTHER

Voice samples and COVID-19 symptom inventories will be collected on participant smartphone devices. No outcomes or feedback is provided on acquired data during trial conduct but will be used for confirmatory data analysis post study
