Development of Voice Biomarkers of Frequent COVID-19 and Long Covid-related Symptoms Based on Data From Users of the Long COVID Companion App

The LIH DDP research team focuses its research topics on vocal biomarkers and Long COVID, among others. Voice is indeed a promising tool to monitor health, as it contains many information on our health and is easy to collect. The development of vocal biomarkers of Long COVID-related symptoms could improve the remote monitoring of the health status of people affected by this disease. The LIH developed the Long COVID Companion (LCC) app in collaboration with the ApresJ20 Long COVID patient association in France to support patients in their daily lives. LCC app users will be invited to participate in this study to collect voice recordings at the same time as health-related data. The objectives of this study are: Primary objective: To develop vocal biomarker candidates for the main Long COVID symptoms (fatigue, brain fog, respiratory problems, sleep issues, stress, anxiety,..) in a population of people with Long COVID. Secondary objectives: * to assess the intra-individual longitudinal evolution of voice characteristics of people with LC * to assess app usability and acceptability in the long-term.

Inclusion Criteria: * Adult (≥18 years old) * Male or female * People with persisting symptoms related to COVID-19 (With Long COVID diagnosis or not) * Adequate understanding of one of the study languages (English, French, German) * Electronically signed informed consent form Exclusion Criteria: ● No specific exclusion criteria
