Well that took awhile: Sonos just announced that a public beta is incoming for Alexa support, a year after saying it was coming. At an event in New York today, the company said that the functionality will be rolling out to all current models of its speakers. Alexa support is provided by your Echo, Echo Dot or other enabled gizmo. With the firm saying Alexa is but the first voice control system, maybe don't be surprised if Google Assistant or Siri show up as well. Sonos is also working to get more developers onboard for its ecosystem, with a "Works with Sonos" certification program.
