Apple Is Working On A Way For Siri To Recognize An Imposter’s Voice

When iPhone users set up Siri for the first time, you will have to say certain phrases so that Siri can learn how you sound. However, it seems that Apple is working on expanding on that feature. According to a patent discovered by Patently Apple, the company is working on a potential new Siri feature that can learn to ignore an imposter’s voice.

What’s interesting is that this patent suggests that Apple could actually use the phone’s accelerometer to detect an imposter’s voice through a voice activity detector. When the person speaks the key phrase, like “Hey Siri”, it passes through an algorithm based on speech rate and also the accelerometer’s signal detector to determine if it is the voice of the device’s owner.

If it is, it will proceed as per usual, if not, it won’t act on the command, simple as that. That being said, the patent seems to be more focused towards the AirPods, but Apple does note in the patent that this system could also be applied to other devices like the iPhone, iPad, HomePod mini, and more.

We should point out that for the most part, Siri is limited in what it can do while your phone is locked, so there’s not much an imposter can do as long as your phone is locked. However, having additional security measures isn’t a bad idea, but whether or not Apple actually implements this remains to be seen.
