How a voice assistant can help patients with Covid-19

The AI-based voice assistant AlloCovid has been launched in France to assist coronavirus patients.

In order to improve the telephone assistance of patients with Covid-19 or with symptoms, in France a voice system based on artificial intelligence has been developed. This is AlloCovid, which answers calls from people with symptoms. In this way, it alleviates the burden of call centers or the health services themselves that attend by telephone.

The system is a development of the Inserm research institute, the University of Paris and the national railway company SNCF. AlloCovid is trained to ask callers questions for information. Their goal is to know what the symptoms are and their severity. To this we must add the previous pathologies and other relevant medical data, which the assistant asks for.

As soon as the conversation begins, AlloCovid asks the user for their zip code and starts asking them questions. At all times it is an anonymous chat, since the interlocutor does not need to give his name. The system is capable of handling up to 1,000 calls at the same time.


When AlloCovid knows the seriousness of the case, it gives the necessary indications or redirects the call to a professional. It is a formula that offers a service especially for the elderly. This group of the most vulnerable population often has difficulties using a self-assessment app.

Ease the burden of care
In these weeks in which the burden of health services has been enormous, ways of relief have been sought. One of them have been the call centers that provided a quick way to briefly evaluate a person. They could offer some basic recommendations.

Applications for self-evaluation have also been launched, following the same protocol. Even health workers who couldn’t work in hospitals have been on the phone for remote consultations. Attempts have also been made to introduce artificial intelligence to filter patients or determine the spread of disease. At the same time that in some places they have used autonomous machines to reduce the exposure of the toilets to contagion.
