How can a device that is only activated by listening not always be listening? If I turn off Siri on my phone the microphone is supposed to go off.
Edit: I know about the wake word. It was a statement on the quote that a device that only works on voice wouldn't be "listening".
- lazerwalker 9y agoWake word detection (listening for a specific phrase, such as "Hey Siri") typically happens using a completely different subsystem from active voice recognition, since it's a much more bounded problem that also needs to run with far lower power consumption. (in the case of Siri specifically, Apple actually has a pretty nifty whitepaper: https://machinelearning.apple.com/2017/10/01/hey-siri.html https://machinelearning.apple.com/2017/10/01/hey-siri.html) That said: right now, common sense would dictate that your phone's battery really can't handle recording full audio at all times, but once that's no longer the case, it does seem problematic that we don't yet have the audio equivalent of putting a piece of tape over your laptop webcam.
- criddell 9y agoIt's always listening for the keyword. The listening isn't problematic, it's the sharing.

I don't know how easy it is with today's smartphones, but it was definitely a thing in the dumbphone era. Similar issues with your laptop or these smart speaker devices.
