Of course it's listening, at all times. Otherwise it would not be able to react to the trigger phrase. What is interesting is whether it sends this data anywhere, and that is probably impossible to ascertain, since it could store it for a while and tunnel it out with innocent looking traffic.

It would be interesting if it could be determined if it stores the passively obtained data at all. If one could monitor writes to memory while in passive state it might give a clue.

Since apparently it can be rooted without affecting the listening process, it should be possible to monitor writes in pure software.

Of course, it may detect the monitoring and avoid writing in those cases /tinfoil

Well, duh, of course it is. Monitoring writes to memory would be pretty interesting
