Cloud-Controlled Speakers

Alexa for Speakers

Multi-Room Experiences with Proprietary Protocols

Device makers with a proprietary multi-room music protocol can connect their speakers to Alexa using a Connected Speaker Skill. Customers can play music by explicitly referring to the room name (e.g., “Alexa, play music in the Kitchen”) or by designating a speaker as the preferred speaker for any room. In this latter configuration, a customer can simply say, “Alexa, play music” and music will play on the preferred speaker automatically. Customers can also use Alexa Cast to cast music to any Alexa-connected speaker from any Alexa Cast compatible mobile app.

Once the music has started, no mention of room names is required for customers to seamlessly control music. Customers can request controls like “pause”, “resume”, “next” or “turn it up.” Customers can also use their voice to control music initiated in third party applications, including music from services not yet offered from Alexa.

Spotlight: Sonos PLAY:1

Sonos PLAY:1 allows customers to use voice to control their entire Sonos home sound system, from specific rooms to curated groups. This mic-less speaker leverages a Sonos Skill to play music via voice using any device with Alexa built-in as the input. Customers can continue to choose to play music on PLAY:1 using the Sonos mobile application, which allows customers to stream music from their favorite supported music service provider and others, and synchronize the music across all of the users' Sonos devices.

The Sonos Skill was developed with the Connected Speaker Skill capability and allows Sonos to continue offering a multi-room home audio experience, something its customers have enjoyed for more than 15 years. The skill connects their custom, time synchronization cloud with the Alexa cloud. Users can play and control music from music services, such as Pandora, TuneIn, Amazon Music, and others, and control on-device features, such as volume and input control, on any Sonos speaker using a device with Alexa built-in. With the Connected Speaker Skill, Alexa passes any directives targeted at a Sonos device via the Lambda down channel to the Sonos cloud, where the request is executed or passed down to the device. The Sonos cloud also provides state information about the media playing back to Alexa so the Alexa App can display information about the media playing on the Sonos device in near instantaneous sync with the Sonos platform.

Build Your Own Connected Speaker Skill

The Connected Speaker Skill offering is ideal for device makers with in-market offerings that have limited hardware capacity to run additional client-side software. By using a skill-based (a.k.a. “cloud-controlled”) implementation, a Connected Speaker Skill prototype can be built in just a few days, and some device makers can launch an offering with little or no modification to the client-side software on their speakers.

Solution components: Connected Speaker Skill

Note: Connected Speaker Skills are restricted to commercial device makers with multi-room protocols for music playback. Talk to your Amazon point of contact to learn more about the offering and request access to the Connected Speaker Skill APIs and Alexa Music Services.
