Amazon reportedly teaching Alexa to distinguish voices

PanARMENIAN.Net - Amazon is working to make its Alexa a better listener. The Seattle-based technology giant has been developing a feature that would allow the voice assistant that powers its Echo line of speakers to distinguish between individual users based on their voices, according to people familiar with Amazon's Alexa strategy. The sources declined to be identified by name because they are not authorized to talk about the company’s future product plans, Time reports exclusively.

An Amazon spokesperson declined to comment.

Alexa, like Apple’s Siri or Microsoft’s Cortana, can interpret and respond to voice commands such as “How’s the weather?” or “What movies are playing tonight?” So far, though, none of the mainstream voice-enabled smart speakers have been able to distinguish who in a household is asking for something.

Amazon’s new feature would match the person speaking to a voice sample, or “voice print,” to verify a person's identity, according to a source. A primary account holder would be able to require a specific voice print to access certain commands. A user would, for example, be able to set it so that a parent's voice would be required to make a credit card purchase or turn on the coffee machine through the Echo.

Amazon has been developing this capability, internally called Voice ID, since at least the summer of 2015. It remained on the Alexa roadmap as recently as late last summer, but it's unclear when or if the feature will launch. The underlying technology has been completed; it's just a matter of integrating the feature into Echo products, one of the sources claimed.

A number of factors could delay or the feature, including privacy concerns, which have become a greater issue for the company. Amazon recently refused to turn over voice records from an Echo user to Arkansas police investigating a murder which took place last November, saying that such recordings should be protected under the First Amendment.
