A year after saying it was coming, Sonos finally announced that a public beta is incoming for Alexa support. At an event in New York today, the company said the functionality will be rolling out to all current models of its speakers. Support is provided by your Echo, Echo Dot or other Alexa-enabled device. But this just the first step, 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.
