Amazon has responded to a letter of inquiry it obtained from U.S. Senator Chris Coons (D-DE) that asks the corporate to element what occurs to prospects’ Alexa voice information and information after they converse to their digital assistant. The Senator’s letter was prompted by a CNET investigation in May, which discovered that Amazon retains voice information until customers manually delete them — and that it could hold textual content transcripts of these voice recordings indefinitely.
In Amazon’s response, revealed in the present day on Senator Coons’ web site, the corporate confirmed CNET’s findings, explaining that it does, in reality, retailer customers’ voice recordings up till the purpose they select to manually delete them.
In different phrases, the recordings aren’t mechanically deleted at any level.
However, the unique CNET report claimed textual content transcripts of the voice information have been nonetheless maintained on Amazon’s servers even after customers deleted their recordings, with “no option for you to delete them.” As CNET defined, Amazon would delete the textual content log from Alexa’s “main system,” however not remaining subsystems.
In Amazon’s response to the Senator’s inquiry, the corporate detailed what precisely it shops and what it doesn’t.
It clarified that transcripts themselves are deleted when a buyer chooses to delete a voice recording utilizing the Alexa Privacy Hub dashboard. But, like CNET had claimed, the transcripts are deleted from Alexa’s “primary storage systems.” Amazon isn’t clear about the place else they could nonetheless reside, saying solely that there’s “an ongoing effort” to make sure the transcripts aren’t saved in every other Alexa storage programs.
Other information can also be retained after voice recordings are deleted, nevertheless it’s of much less concern.
“We do not store the audio of Alexa’s response,” Amazon additionally famous. “However, we may still retain other records of the customers’ Alexa interactions, including records of actions Alexa took in response to the customer’s request,” the corporate mentioned.
These information of actions could also be retained by both Amazon or a third-party developer when an Alexa ability (voice app) is concerned.
“For example, for many types of Alexa requests — such as when a customer subscribes to Amazon Music Unlimited, places an Amazon Fresh order, requests a car from Uber or Lyft, orders a pizza from Domino’s, or makes an in-skill purchase of premium digital content — Amazon and/or the applicable skill developer obviously need to keep a record of the transaction.”
This appears sensible. After all, in the event you order an Uber or a pizza, or began a subscription, you’d count on there to be a file of that with the corporate the place the order was positioned. And nobody actually asks their pizza place to wipe their pizza ordering historical past.
Amazon additionally mentioned that for different forms of requests — like setting a recurring alarm, asking Alexa to remind you of one thing, placing a gathering in your calendar or messaging a pal — prospects wouldn’t count on deletion of the voice recording or the info, nor would they need that, because it may forestall Alexa from performing the duty.
The firm defined why it makes use of transcripts, saying that it helps to coach and enhance Alexa’s machine studying programs, and to supply a log to prospects immediately of what they mentioned, what Alexa heard and the way the digital assistant responded.
Additionally, Amazon confirmed the system stops recording as quickly because the buyer stops talking — as indicated by the blue mild on the Echo gadget or, optionally, a tone that may be set to play.
The firm then goes into extra technical element concerning the brief buffer on the gadget, which is constantly overwritten, and says that Alexa is designed to file and course of as little audio from prospects as doable as processing audio not supposed for Alexa could be pricey and of no worth to Amazon.
The authentic inquiry from the Senator gave Amazon a June 30 deadline, and the response letter was dated June 28.
Coons in the present day applauded the timeliness of the response, however mentioned there have been nonetheless questions.

“I appreciate that Amazon responded promptly to my concerns, and I’m encouraged that their answers demonstrate an understanding of the importance of and a commitment to protecting users’ personal information,” he mentioned, in an announcement revealed to his web site.
“However, Amazon’s response leaves open the possibility that transcripts of user voice interactions with Alexa are not deleted from all of Amazon’s servers, even after a user has deleted a recording of his or her voice. What’s more, the extent to which this data is shared with third parties, and how those third parties use and control that information, is still unclear.  The American people deserve to understand how their personal data is being used by tech companies, and I will continue to work with both consumers and companies to identify how to best protect Americans’ personal information,” he added.

While many corporations retain person information indefinitely, the elevated deal with client privateness as regulators examine huge tech is beginning to drive change. For instance, final week Google rolled out a brand new function that lets customers configure their account settings to mechanically delete location historical past on iOS and Android. But that is after years of hoovering up person information, and nonetheless requires handbook motion.
Still, many would argue that voice assistants ought to at the least provide an identical setting: a technique to set voice information to auto-delete, as an alternative of getting to recollect to take action manually.
It’s value mentioning that Amazon is just not alone in hoarding person voice information.
Google additionally saves voice and audio clips to customers’ accounts with an choice to assessment and delete recordings. While saving information is its default, it does permit customers to show voice and audio exercise off, if they like. Apple, in the meantime, saves Siri voice recordings for six months, then saves a replica of the info in a extra anonymized trend for as much as two years longer.
But extra broadly, there are considerations round Amazon’s assessment course of itself and its lack of consideration to person privateness.
As Bloomberg lately discovered, Amazon staff and contractors through the assessment course of had entry to the recordings, in addition to an account quantity, the person’s first title and the gadget’s serial quantity. And they have been additionally discovered to have been sharing audio clips in inner firm chat rooms — both to get assist with transcribing or to have amusing at a humorous recording.
In different phrases, there’s not a tradition of privateness at Amazon in relation to how an organization ought to respect client’s non-public information. That’s completely different from Apple’s stance as of late, the place it goals to stability its want for some information retention with customers’ want for elevated privateness.
In mild of most huge tech corporations’ incapacity to correctly self-police, there’ll finally be laws put into place, as these corporations insert themselves ever additional into our lives. Now, they’re not simply gathering information as we kind right into a keyboard or as we transfer around the globe with a cellphone; they’re in our houses, listening to us and our kids as we speak to their programs immediately.
Amazon was requested for additional remark relating to Coons’ assertion.
