I have a suspicion that it could be something that does voice recognition via the gyroscope data. I believe so for many reasons-

1. Gyroscope creates a lot of data for every millisecond, so it doesn't makes any sense to send all of it over to the server.

2. You only need to recognise certain keywords/movements of the user for somewhat accurate ad-tracking and behavourial analysis.

3. You don't need to prompt the user to allow access to it.
