Sending all microphone input to a remote server would be really bad for battery life and data usage.
It still works even in airplane mode.
I agree that they probably only send speech recorded after the activation words. However, I don't arguments think your arguments hold up. Speech data compresses exceptionally well and generally requires lower sampling rates and/or resolutions. So, it's feasible to compress the speech signal (possibly hardware-assisted), buffer it, and send it to the server at some regular interval or when the user wakes the phone.
- organsnyder 10y agoYes, it is possible for them to be sending all recorded sounds (even if the hotwords are not detected) to a remote server. However, as discussed above, there would be no legitimate reason for doing so—it is demonstrably true that the phone is able to recognize the hotwords even when a remote server is not reachable.
- Symmetry 10y agoIf you're only interested in spying, sure. If you want the phone to respond when a user says "ok, google" rather than a minute later it wouldn't work.
