Researchers say the technology (Calling Emergency Services; Smart Assistants in Amazon Echo And Google Home) was able to detect agonal breathing 97 percent of the time from up to 20 feet away.
Calling Emergency Services in Amazon Echo And Google Home
In this paragraph, I’m going to discuss about Calling Emergency Services in Amazon Echo And Google Home. Firstly Smart speakers and smart assistants are not just about commanding it to play music or tell you the weather or book an Uber for you. Researchers at the University of Washington have developed and artificial intelligence (AI) tool that allows smart speakers(Amazon Echo And Google Home) to detect signs of a heart attack or cardiac arrest, and alert emergency services as well as friends and relatives. In the research published in NJP Digital Medicine, researchers Justin Chan, Thomas Rea, Shyamnath Gollakota and Jacob E. Sunshine say that the technology was able to detect agonal breathing 97 percent of the time from up to 20 feet away.

The researchers say that they sourced the pre-heart attack or pre-cardiac arrest agonal breathing recording samples from the 9-1-1 emergency calls between the years of 2009 and 2017, from the Public Health-Seattle & King County, Division of Emergency Medical Services. This dataset included 162 calls, roughly about 19 hours of clear recordings of agonal breathing. Those who may be suffering with sudden cardiac arrest or initial stages of a heart attack struggle with irregular gasps of breath, also known as agonal breathing. If they are alone at the time, they may be unable to seek help.

“For each occurrence, we extract 2.5 seconds worth of audio from the start of each agonal breath. We extracted a total of 236 clips of agonal breathing instances. Given the relatively small size of our agonal breathing dataset. We augment the number of agonal breathing instances with label preserving transformations. A common technique applied to sparse datasets. We augment the data by playing the recordings over the air over distances of 1, 3, and 6 meters. In the presence of interference from indoor and outdoor sounds with different volumes and when a noise cancellation filter is applied,” say the researchers. The indoor and outdoor sounds could include the noise made by air-conditioners, pets and even traffic movement outside.
In addition Researchers say the technology (Calling Emergency Services; Smart Assistants in Amazon Echo And Google Home) Was able to detect agonal breathing 97 percent of the time from up to 20 feet away.
The recordings were captured on different devices. Including an Amazon Alexa smart speaker, an Apple iPhone 5s and a Samsung Galaxy S4 to get 7316 positive samples.
In conclusion This tool is currently in the testing phase. It by smart speakers like Amazon Echo And Google Home . Similar to how an Amazon Alexa speaker can enable a skill, and will detect the breathing patterns of users. Incidentally, this process will run on the processors built inside smart speakers and will operate locally. The researchers want to further tune the algorithms to eliminate the false alarms.
