Amazon Echo might soon be able to tell voices apart - SlashGear

Amazon arguably kicked off the "personal assistant in a can" line of products, so it's almost fitting that it also be the first to implement one of the most needed feature for smart speakers. These devices can already recognize and understand voices and speech, but they can't really differentiate one voice from the next, which makes for a sometimes hilarious, sometimes frightening situation. Amazon, however, is tipped to be working on a certain "Voice ID" feature that would put those worries to rest. Neither of them can really tell their owner's voice from other voices within earshot. That has lead to rather comical instances where Echo would try (and fortunately fail) to order toys for kids or Google Home responding to triggers in an advertisement for Google Home. It is a security nightmare waiting to happen.
