“You cough it can help us in the fight against the pandemic in the City and no, it is not science fiction. IATos is a system of artificial intelligence that detects disease patterns through cough audios. While it is in a experimental stage, already reached a 88% accuracy. Not bad, huh? You are now adding coughs to refine your algorithm and the idea is that soon I will complement the remote testing and diagnosis that the City does through me. ”
The message is issued by Boti, the WhatsApp chat of the City in which you can check for coronavirus symptoms and do all kinds of procedures.
The cough study seeks to know if the person may be infected. The objective of this tool is supplement medical triage (system of selection and classification of patients in emergency services) that is done through Boti, so that later the person is swabbed, if necessary, to confirm or reject the diagnosis.
“We have already collected more than 6,000 coughs, half belong to negative cases and the other half to positive cases. These data are now available in an open domain dataset and available so that any organization or person can deepen the development and analysis of systems of this type and advance projects to be able to face COVID19 using better tools, “said Fernando. Benegas, Secretary of Innovation of the City.

The official explained that in the world there are studies similar to the Argentine one, although only here is a collection of coughs with a CRP associated with each one. “This,” he affirmed, “will allow solutions like ours to accelerate, collaborating with the world of research and strengthening the remote diagnostics “.
The next goal is to “keep training the machine learning algorithm to achieve a higher level of system precision. We experimentally reached a 88% accuracy thanks to the training of the neural network. We present these results to Cornell University in the United States and we are presenting them to the academic community. “
The project seeks to detect the SARS-Cov-2 Coronavirus through machine learning algorithms, based on sounds of voice, breathing, and coughing. In this way, the City Government uses technology to accelerate and enhance the remote testing and diagnosis strategy.
The information used is absolutely confidential to protect the privacy of the participants, and they are only accessible to doctors and health authorities.
How does it work?
The person who wants to know if their symptoms are compatible with COVID19, will answer the questions of the protocol defined by the health authorities and then will send your cough through a voice memo. The chatbot will be able to recognize and analyze it through a neural network developed to differentiate if it matches the patterns of positive cases.
In fact, through Boti (which works on 11-5050-0147) you can already consult for other symptoms of covid. The system guides the neighbor who is contacted, through a triage of symptoms by which it ends up recommending or not consulting the doctor.
In addition to the symptom query, “Boti” is being used to keep track of close contacts of patients with covid. Every day, the bot communicates with more than 15,000 people to check that they have not started having symptoms. This control is maintained for 10 to 14 days.
