The evolution of voice technology, audio signal analysis and natural language processing/understanding methods have opened the way to numerous applications of voice tracking and analysis in the field of healthcare. Voice is a rich medium, in which a lot of information can be found, providing that we know how to isolate and make use of it. A vocal biomarker can be defined as a signature, a feature or a combination of features from the audio signal of the voice that is associated with a clinical outcome and can be used to monitor patients, diagnose a condition or grade the severity or the stages of a disease or for drug development. Covid-19 is a respiratory condition, affecting breathing and voice, and causing, among other symptoms, dry cough, sore throat, excessively breathy voice and typical breathing patterns. These are all symptoms that can make patients’ voices distinctive, creating recognizable voice signatures and enabling the training of algorithms to predict the presence of a SARS-COV-2 infection or as a tool to grade the severity of the disease. In our context, voice is a promising data source to identify vocal biomarkers associated with Covid-19-related outcomes such as respiratory symptoms, fatigue or stress. Developing Covid-19 vocal biomarkers would help to offer a better remote monitoring of people with Covid-19 based on digital technologies.


Our team aims at identifying vocal biomarkers of Covid-19 related symptoms, based on audio recording from the large prospective Predi-COVID cohort study1.


Training and research environment

The “Deep Digital Phenotyping Research Unit” develops a transversal research activity within the Department of Population Health at the frontier between digital epidemiology and data science, to leverage real-world data to improve population health.

The Master student will directly contribute to the identification of vocal biomarkers for Covid-19 monitoring. He/she will lead a project on the analysis of a large annotated audio dataset from the Predi-COHORT study to decompose the audio signals and then apply AI-based algorithms and statistical approaches to identify features associated with Covid-19 related outcomes. He/She will have to take in charge the literature review, the pre-processing of the data, the data analysis and the preparation of a scientific article. He/she will be supervised by Dr. G. Fagherazzi, Research Leader of the Digital Epidemiology Hub, in association with experts in audio signals and artificial intelligence methods. This internship position may lead to a PhD opportunity in digital epidemiology.
