UW-Madison researchers have discovered a way to mimic people’s voices using household items that, under the right dimensions, can effectively elude voice security technology.
Professor of Electrical and Computer Engineering Kassem Fawaz and Ph.D. student Shimaa Ahmed have developed a mathematical model that could allow almost anyone to imitate the resonance of another person’s voice with a simple tube. As long as a person could nail down the frequency of a voice with a PVC pipe that, based on the algorithm, had the correct width and length, they could trick the security technology 60% of the time.
Researchers’ attempts to dupe the security technology were 10 times more successful with that PVC pipe than if people tried to impersonate another with their voice alone.
The research suggests security systems within voice recognition software aren’t as secure as…
