Sonos version 8.2.3 is now available for the Sonos One (other Sonos devices will stay on 8.2.2). This update improves Alexa responsiveness for Sonos One users in US, UK, Germany, and Austria.
You should find that Alexa is getting better at listening, with a decrease in the times Alexa speaks up when not called. Alexa on Sonos One is now more likely to carry out your desired action when requested; especially when it’s noisy, when the speaker is further away, or when speaking quietly.
Update within your Sonos app by going to More > Settings > Online Updates.
We’re continuing to work with Amazon and the Alexa team to improve Sonos One voice control. You can expect to see more developments as we go. Let us know what you think of the changes. We’d love to hear from you.
