How realistic are AI-generated voice impersonations?

AI-generated voice technology has reached concerning levels of realism. Modern voice synthesis can create natural-sounding speech that mimics human conversation patterns, complete with natural pauses, filler words, and authentic intonation. These voices are increasingly capable of deceiving people on phone calls, particularly in high-pressure scenarios when combined with other social engineering tactics. Our clients implementing military-grade security services have found that cross-channel behavior analysis significantly improves their ability to identify these sophisticated voice-based social engineering attempts.
