Speech is critical to detecting suicidal ideation and a key to understanding the mental and emotional state of people experiencing it. Suicide hotline counselors are trained to quickly analyze speech variation to better help callers through a crisis.

But just as no system is perfect, there is room for error in interpreting a caller’s speech. In order to assist hotline counselors to properly assess a caller’s condition, Concordia Ph.D. student Alaa Nfissi has developed a model for speech emotion recognition (SER) using artificial intelligence tools. The model analyzes and codes waveform modulations in callers’ voices. This model, he says, can lead to improved responder performance in real-life suicide monitoring.

A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet.

The planet hunters spotted the Neptune-like planet as it crossed in front of its host star, temporarily dimming the star’s light in a way akin to a solar eclipse on Earth...

Patients with growth hormone receptor deficiency, or Laron syndrome, appear to have lower than average risk factors for cardiovascular disease, according to a new study.

A new study highlights possible cardiovascular health advantages in individuals with a rare condition known as growth hormone receptor deficiency (GHRD), also called Laron syndrome.

GHRD, which is characterized by the body’s impaired ability to use its own growth hormone and results in stunted growth, has been linked in mice to a record 40% longevity extension and lower risks for various age-related diseases...

Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use.

The multi-university and industry research team led by computer scientists at University of California San Diego will present their work at the 2024 ACM ASPLOS Conference that begins tomorrow...
