Echo has an always on microphone as well. The story is that audio gets sent to a temporary buffer on a server somewhere to listen for your trigger word, and I trust them, but it would be so easy to start storing that data if they wanted, (or rather, the NSA wanted).
I'm not normally really intense about privacy (relative to other tech people I know), but all these devices creep me out.
- Jarwain 10y agoI was under the impression that the audio is stored locally while listening for the trigger word. Once the trigger word is recognized, Alexa begins recording and sends the result to be processed.
- spdustin 10y agoNo, the processing for the trigger is done locally, no network communication until the trigger is recognized. That's why you can only have one of a couple of trigger words.
- kajecounterhack 10y agoThe same is true of most modern android phones with Google Now AFAIK. E.g Moto X was one of the first phones with a low power dedicated ASIC for wakeup-word recognition to further make it sustainable on mobile devices.
- vlunkr 10y agoYeah I read somewhere that it was all sent off, but everything else I've looked at says it's all local.
- hackmiester 10y agoThe data is not sent to a server all the time - only when someone is using the device. Source: tcpdump
- joezydeco 10y agoDo you have a rough guess as to how compressed the outbound audio is?
