AI Detects Depression in Voice Tone

AI Detects Depression in Voice Tone

Depression is a reality for many people, but due to the wide scope of symptoms and varying degrees of severity, it is often difficult to diagnose.

Researchers at the Computer Science and Artificial Intelligence Laboratory are attempting to combat this difficulty. They aimed at making diagnosis simpler for doctors and individuals by creating an algorithm that when taught to a machine, can detect depression simply by listening to the tone of your voice.

The technology is in its infancy, so while it promises to be a wonderful tool, there are still some hurdles to overcome. The algorithm is based on a study that used text and audio data from 142 interviews with patients; 30 of the patients had been diagnosed with depression, and the machine was able to correctly identify the other patients with a 77 percent success rate.

Tuka Alhanai, a researcher from the laboratory and one of the developers of the algorithm, said: "If you want to deploy models in a scalable way, you want to minimize the amount of constraints you have on the data you’re using."

Smoke From Canadian Fires Reaches Europe, Says EU Climate Monitor

Heavy smoke from intense wildfires in Canada has reached northwestern Europe, the European Union's climate monitoring service said on Tuesday.

The huge plumes are at very high altitude and do not pose an immediate health risk, it said in a statement.

"Smoke originating from the wildfires in the Canadian provinces of Manitoba and Saskatchewan has been transported across the Atlantic," the Copernicus Atmosphere Monitoring Service (CAMS) said.

Satellites tracked the smoke in mid-May, with some plumes reaching as far east as Greece and the eastern Mediterranean.

"A second, much larger, smoke plume crossed the Atlantic during the last week of May, reaching northwestern parts of Europe on June 1," CAMS said.

Additional plumes are expected to shade the continent in the coming days.

Wildfire smoke is comprised of gaseous pollutants such as carbon monoxide, along with water vapor and particle pollution, which can be particularly hazardous to health.

A high concentration of carbon monoxide is expected to pass over northwestern France, including the Paris Basin, on Tuesday.

The high-altitude smoke headed for Europe is not expected to have a significant impact on surface air quality, but is likely to result in hazy skies and reddish-orange sunsets.

Manitoba in central Canada is experiencing its worst start to the fire season in years due to drought, and Saskatchewan to the west declared a state of emergency at the end of May, evacuating thousands of residents.

"Central regions of Canada have experienced a very intense few weeks in terms of wildfire emissions," said Mark Parrington, scientific director at CAMS.

Canadian authorities have forecast a more intense fire season than usual this summer in central and western Canada, due in particular to severe or extreme drought.

Elsewhere, extensive forest fires have been raging in Russia's Far Eastern Federal District since early April, particularly east of Lake Baikal, generating carbon emissions of around 35 million tons, Copernicus reported.
