Deepfake Audio Has A Tell – Researchers Use Fluid Dynamics To Spot Artificial Imposter Voices

Imagine the following scenario. A phone rings. An office worker answers it and hears his boss, in a panic, tell him that she forgot to transfer money to the new contractor before she left for the day and needs him to do it. She gives him the wire transfer information, and with the money transferred, the crisis has been averted. The worker sits back in his chair, takes a deep breath, and watches as his boss walks in the door. The voice on the other end of the call was not his boss. In fact, it wasn’t even a human. The voice he heard was that of an audio deepfake, a machine-generated audio sample designed to sound exactly like his boss. Attacks like this using recorded audio have already occurred, and conversational audio deepfakes might not be far off. Deepfakes, both audio and video, ha...

Highway Departments Find Bats Roosting Under Bridges With The Help Of Artificial Intelligence

Tianshu Li, University of Virginia The Research Brief is a short take about interesting academic work. The big idea Photographs and computer vision techniques using artificial intelligence are able to detect the presence of bats on bridges automatically with over 90% accuracy, according to our new study. More than 40 species of bats are found in the U.S., and many of them are endangered or threatened. Bats often nest by the hundreds or thousands underneath bridges, so transportation departments are required to survey for them before conducting repair or replacement projects. I conducted the recently published study with colleagues at the University of Virginia’s MOB Lab in collaboration with the Virginia Transportation Research Council. Bridge surveys are important for protecting threa...

Explainable Artificial Intelligence Can Help Humans Innovate – Here’s How

The field of artificial intelligence (AI) has created computers that can drive cars, synthesize chemical compounds, fold proteins and detect high-energy particles at a superhuman level. Understanding how artificial intelligence algorithms solve problems like the Rubik’s Cube makes AI more useful. Roland Frisch via Wikimedia Commons, CC BY-SA However, these AI algorithms cannot explain the thought processes behind their decisions. A computer that masters protein folding and also tells researchers more about the rules of biology is much more useful than a computer that folds proteins without explanation. Therefore, AI researchers like me are now turning our efforts toward developing AI algorithms that can explain themselves in a manner that humans can understand. If we can do this, I belie...

Lost your job due to coronavirus? Artificial intelligence could be your best friend in finding a new one

Millions of Americans are unemployed and looking for work. Hiring continues, but there’s far more demand for jobs than supply. As scholars of human resources and management, we believe artificial intelligence could be a boon for job seekers who need an edge in a tight labor market like today’s. What’s more, our research suggests it can make the whole process of finding and changing jobs much less painful, more effective and potentially more lucrative. Make me a match Over the last three years, we’ve intensely studied the role of AI in recruiting. This research shows that job candidates are positively inclined to use AI in the recruiting process and find it more convenient than traditional analog approaches. Although companies have been using AI in hiring for a few years, job applicants ...

White Supremacy and Artificial Intelligence

Developing technology that doesn’t perpetuate racism demands putting social values before profit. In her new book Race After Technology: Abolitionist Tools for the New Jim Code, Ruha Benjamin breaks down the “New Jim Code,” technology design that promises a utopian future but serves racial hierarchies and racial bias. When people change how they speak or act in order to conform to dominant norms, we call it “code-switching.” And, like other types of codes, the practice of code-switching is power-laden. Justine Cassell, a professor at Carnegie Mellon’s Human-Computer Interaction Institute, creates educational programs for children and found that avatars using African American Vernacular English lead Black children “to achieve better results in teaching scientific concepts than whe...
