For all of Alexa's many skills, one major thing Amazon's voice assistant is currently missing is the ability to distinguish who is actually speaking to it. According to a new report from Time magazine, however, the online retail giant is currently working to make that a reality. As Time's sources inside Amazon explained, the feature would use a "voice print" to verify each speaker's identity and primary account holders could set Alexa to require their voice print for specific commands. That means that the person with the credit card tied to the account could set their Echo to require their voice for purchases and restocking the fridge. The Voice ID feature, which has reportedly been in development since 2015, could also help ease some of those Alexa headaches and accidental shopping sprees.
