Your voice can be cloned in just a few seconds! The Ministry of National Security reveals why people are silent for three seconds when receiving calls from strangers

Kuai Technology reported on October 11 that artificial intelligence technology is developing rapidly. While empowering daily life, it has also become a tool for criminals to commit new types of fraud. Many people receive a call from a stranger and will habitually answer "Hi, who's there" as soon as the call is answered, but most people do not realize that these casual words may cause the leakage of their own voiceprint information. The Ministry of National Security issued a safety reminder: The current technical threshold for AI voiceprint cloning continues to decline, and it only takes a few seconds of human voice material to generate a highly simulated fake voice. With its powerful audio and video analysis capabilities, AI can also extract standardized personal biometrics in batches from various types of information published online. Some informal application software and network platforms will also over-collect or even steal sensitive data such as faces and voiceprints of users under the guise of face verification. Relevant research shows that AI can also estimate a person's posture and physiological characteristics based on facial images, and use gait information to further determine age and capture emotional changes. Once criminals master this information database, combined with genetic data, they can lock in personal identities and deduce family relationships. In telecom fraud scenarios, many criminals deliberately remain silent after making calls and do not actively communicate, just to induce the person who receives the call to speak first. As long as they intercept a few seconds of valid human voice, they can use AI to complete the voiceprint and forge the voice of the person involved. After obtaining the cloned voiceprint, the scammer will pretend to be the person involved and contact relatives, friends and colleagues, fabricate various emergency reasons to ask for money, and will also pretend to be relatives and friends to lay traps for the victim. Faced with this new type of risk, the security department has given a simple and feasible method to deal with it: after receiving an unknown call, remain silent for three seconds, do not speak immediately, and wait for the other party to speak first. If there is still no movement on the other side of the receiver after three seconds, the call is likely to be a safety hazard and you should hang up without continuing the conversation.
