Researchers at the University of Eastern Finland have found skillful voice impersonators are able to fool state-of-the-art speaker recognition systems, posing a significant security risk.
The researchers analyzed the speech of two professional impersonators who mimicked eight Finnish public figures, and they also examined acted speech from 60 Finnish speakers who participated in two recording sessions. The speakers were asked to modify their voices to fake their age, attempting to sound like a senior citizen and like a child.
The researchers found the impersonators were able to deceive automatic systems and human listeners in mimicking some speakers.
For the acted speech aspect of the study, the researchers found both automatic systems and human listeners were tricked by participants who altered their voices to sound like children more so than those who changed their voices to sound like senior citizens.
