Hi @mtwomey
Thanks for flagging this - Sonos Voice Control should not be mentioned in the S1 guide at all. SVC is only compatible with S2 and will not run on S1, even on a device that has a microphone.
Although Alexa and Google Assistant can command S1 devices with no mic, they can only do so because they are on the same Sonos system. I think this must be where this error came from. SVC cannot be on the same system as S1 devices, therefore cannot command them.
I’ve passed this up the chain and it should be corrected sometime soon. Thanks again!
