Press invites reference UI elements present in the FCC filing that appear to be on-device controls for playing, pausing, navigating, and activating voice control. The invites also feature a prominent Rolling Stones-esque mouth that � as far as we can tell � is a nod to voice control capabilities. Check out TechCrunch’s report for a side-by-side look at the invites TechCrunch and The Verge received � they’re different styles that, when combined, reveal even more of the UI controls. (Android Central also received the second invite � we’ll see you there!)Sonos’s smart speaker is expected to include far-field voice recognition technology (like the far-field microphones in Amazon Echo devices and may include support for multiple voice assistants. How that would work, exactly, isn’t mentioned in the FCC filing, but it could get confusing shuffling between Amazon’s Alexa voice assistant, Google Assistant, and � if applicable � any smart assistant Sonos brings to the table.No word yet on when this product will launch or how much it’ll cost, but folks are starting to bet that Sonos will try to beat Apple’s HomePod to market, which is expected in December.
