Sonos is almost certainly going to throw its hat in the smart speaker ring on October 4, when it’s hosting an event in NYC. We know about its forthcoming voice-enabled speaker because such a device was filed with the FCC, and the filing describes a speaker with voice control and far field microphones capable of picking up voice commands in a big room and filtering out background noise.

The invitation TechCrunch received features an open mouth, and in the lower left corner, an image that was present in the FCC filing which looks like a controller graphic complete with a microphone icon and play/pause controls. Taken together, it’s basically a lock that Sonos will reveal its own voice-enabled hardware on October 4.
