How to assess the risk of virus transmission through speech?

As early as spring 2020, several members of the LPL and La Conception Hospital were working on the risks of spreading the SARS-Cov-2 virus, particularly when dealing with swallowing disorders or dysphonia. Based on this initial work, the SpeedVel study was financed and carried out in collaboration with colleagues from the Institut Universitaire des Systèmes Thermiques et Industriels in Marseille, to analyze droplets emitted in oral communication situations, in order to better assess the risk of contamination.

We are pleased to announce the publication of detailed results from the SpeedVel project in the journal Language Resources et Evaluation:

Abstract:
Because of Covid-19 we were confined behind our screens which resulted in disrupting the dynamics and class atmosphere. Despite or thanks to the distance, we have worked to maintain the previously created link. This article relates an experience with multilingual students in FFL courses at the University of Aix-Marseille during the lockdown period of spring 2020. It questions the use of multimodal resources to maintain interactive contact, enrich exchanges and stimulate the pleasure of learning together. It is structured in three parts : 1) planning online lessons, 2) maintaining group dynamics and 3) the place of the body and sensations in online class.

Should we whisper to avoid transmitting SARS-CoV-2?

Update July 27: 

The study on which the recent interview with Antoine Giovanni (LPL / AP-HM Marseille) on BFMtv.com (June 2020) is based has just been published in the journal "European Archives of Oto-Rhino-Laryngology":

Giovanni, A., Radulesco, T., Bouchet, G. et al. Transmission of droplet-conveyed infectious agents such as SARS-CoV-2 by speech and vocal exercises during speech therapy: preliminary experiment concerning airflow velocity. Eur Arch Otorhinolaryngol (2020). https://doi.org/10.1007/s00405-020-06200-7
