If the phone is not unlocked, many users should have heard a kind greeting like "Please unlock the phone" when using the voice assistant. Samsung may already have a solution to this dilemma. On November 26, it was reported that the Samsung Galaxy S21 series released by Samsung early next year will provide voice unlocking function.

Because the mobile phone involves a lot of user privacy, and the security of common voiceprint recognition is too low, the voice assistant usually needs to be unlocked before it can be used with full blood. According to sammobile, Samsung's upcoming One UI 3.1 system (expected to be the first release of the Galaxy S21 series, after all, Galaxy S10 launched One UI 1.1, and S20 launched One UI 2.1) allows users to select Bixby voice unlocking in the lock screen security settings.

That is to say, on the Galaxy S21 series, the security level of voice recognition is promoted to be close to the level of fingerprint and face unlocking. But I don't know what kind of black technology Samsung uses. In fact, Bixby used to have a voice unlocking function, but it needs a specific voice password to unlock the phone (just like saying a mantra), and this function has been removed.

As we all know, the security of voiceprint recognition is very low. A "Hey Siri" often appears in the computer office, arousing the embarrassment of many iPhones. And even if the accuracy of voice recognition is improved, voiceprint recognition is difficult to prevent the "attack" of the recorder. If the disclosure is true, the natives are very interested in it. How does this work?
