The Hiya Deepfake Voice Detector uses artificial intelligence to determine if the voice on screen is legitimate or faked. The company claims the tool has a 99% accuracy rate and says it can verify (or debunk) audio in just a few seconds.

"Our models are trained to detect subtle audio artifacts unique to AI-generated voices -- imperceptible to the human ear but identifiable by machine learning algorithms -- and just a second of audio is enough to detect their presence," Patchen Noelke, vice president of marketing for Hiya, tells Fast Company.

I put the free tool to the test and found that while it certainly does catch some deepfakes, its accuracy varied.
