Sungkyunkwan University research team develops voice security technology to detect spoofed audio

A research team at Sungkyunkwan University has developed a voice security technology designed to combat increasingly sophisticated voice deepfake crimes, the university said Wednesday. The research team, led by Park Eun-il, a professor in the Department of Applied Artificial Intelligence, demonstrated that the technology can detect manipulated audio inserted into genuine voice recordings. The technology is expected to have broad applications in areas related to everyday security, including voice phishing prevention, voice-based identity verification for financial services and digital evidence analysis. The team used artificial intelligence (AI) to analyze subtle changes in audio signals and speech patterns that are difficult for the human ear to distinguish, pinpointing the exact locations of manipulated speech to within one second. Two papers by the team have been accepted for presentation at Interspeech 2026, an annual conference of the International Speech Communication Association on speech science and technology, scheduled for Sept. 27 to Oct. 1 in Sydney, Australia.
