It's the Echo news we've been waiting for - you can now synchronise music across multiple Amazon Echo devices in your home. Once the group is made, like "downstairs" for devices in the first floor, users can say phrases like "Alexa, play John Mayer downstairs" to hear their music through multiple Echo devices. It seems to be the current OEM trend, with the success of Amazon Echo devices, Google Home, Apple HomePod, etc. The new feature is now limited to US, UK, and German residents. Spotify support is in the works and should be released hopefully sooner than later. Also, you can't use the Echo Dot's Bluetooth connection with this feature, so you'll have to plug a speaker into its 3.5-mm jack instead. Once that's done - say you've added all of the speakers on your lower floor to the same "downstairs" group - you only need to say "Alexa, play Frank Sinatra downstairs" to have the silky tones of Ol' Blue Eyes begin playing across all speakers in the group.
Amazon is introducing new tools that enable AVS device makers to integrate with Amazon Alexa Multi-Room Music.
You can now group up multiple Echo's for music playback thanks to a new feature that Amazon has started to roll out to its Alexa software. Amazon has confirmed today that its Echo devices now have support for multi-room audio. It seems like Amazon is going after that, by making the sound in the Echo better.
Amazon also debuted a tool for developers that lets third-party manufacturers link their audio systems to Amazon's Echo and the smaller Echo Dot. Ask "Alexa, play classical music for studying", or "Alexa, play pop music for focusing".
Both the AVS Multi-Room SDK and Connected Speakers API are available starting today in the United States, United Kingdom, and Germany.
