Is Google Now violating my privacy?

Episode 1069 (1:28:57)

Neil from Sulfur, OK
Motorola Moto X

Neil got the Motorola Moto X and he loves it. Leo says that from a functional point of view, it's a great phone. The voice controls are great. Neil says that the Google Now's capability of always listening freaks him out, though. Leo says that there's no worry about that. It's very passive. It's not sending what he's saying up to the server, that would be crazy. It just listens for him to say "OK Google Now." When it gets that, it knows to wake up. It does that by comparing the wave form of his voice stored on the phone itself.
