Researchers Take on the Growing Risk of Fake Audio
Romit Barua, Gautham Koorma, and Sarah Barrington, all from the MIMS ’23 program, initially presented their research on voice cloning as their final project for the Master of Information Management and Systems degree. Barrington has since become a Ph.D. student at the I School. Teaming up with Professor Hany Farid, they delved into techniques to distinguish between a real and a cloned voice designed to mimic a specific person . Professor Farid initially underestimated the capabilities of AI-powered voice cloning but acknowledged the rapid evolution of the technology. The team's research focused on analyzing perceptual features in audio samples, particularly looking at patterns in audio waves. Real human voices, they observed, tend to have more pauses and variations in volume due to filler words and movement during recording. Identifying pauses and amplitude (voice consistency and variation) became key indicators of authenticity . Taking a more detailed approach, the team employed ...
