Google AI could soon use a person’s cough to diagnose disease

Machine-learning system trained on millions of human audio clips shows promise for detecting COVID-19 and tuberculosis.

A team led by Google scientists has developed a machine-learning tool that can help to detect and monitor health conditions by evaluating noises such as coughing and breathing. The artificial intelligence (AI) system1, trained on millions of audio clips of human sounds, might one day be used by physicians to diagnose diseases including COVID-19 and tuberculosis and to assess how well a person’s lungs are functioning.

AI detects eye disease and risk of Parkinson’s from retinal images

This is not the first time a research group has explored using sound as a biomarker for disease. The concept gained traction during the COVID-19 pandemic, when scientists discovered that it was possible to detect the respiratory disease through a person’s cough2.

What’s new about the Google system — called Health Acoustic Representations (HeAR) — is the massive data set that it was trained on, and the fact that it can be fine-tuned to perform multiple tasks.

  Silicon Valley Is Pricing Academics Out of AI Research Stanford University's Fei-Fei Li, an ACM Fellow known as the "godmother of AI," pressed President Joe Biden, following his State of the Union address, to fund a national warehouse of computing power and datasets to ensure the nation's leading AI researchers can keep pace with big tech firms. Said Li, "The public sector is now significantly lagging in resources and talent compared to that of industry. This will have profound consequences because industry is focused on developing technology that is profit-driven, whereas public sector AI goals are focused on creating public goods.".  The Washington Post; Naomi Nix; Cat Zakrzewski; Gerrit De Vynck (March 10, 2024)

Google DeepMind Unveils AI Football Coach Researchers at Google DeepMind collaborated with English Premier League club Liverpool to develop an AI football coach. The geometric deep learning model TacticAI was trained on a dataset of 7,176 corner kicks from the English Premier League from 2020 to 2023. After analyzing corner kicks with different player configurations, it can suggest positional improvements. In a study, experts including data scientists, a video analyst, and a coaching assistant chose TacticAI's recommendations over existing strategies 90% of the time.
