Cloud-Controlled Soundbars & AVRs

Alexa for Speakers

Multi-Room Experiences with Proprietary Protocols

Device makers with a proprietary multi-room music protocol can connect their soundbars & AVRs 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 Living Room”) or by designating a device as the preferred speaker for any room. In this latter configuration, a customer can say, “Alexa, play music” and music will play on the preferred device automatically. Customers can also use Alexa Cast to cast music to any Alexa-connected device 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 simply 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.

Customers can also control their home theater experience using voice, including adjustment of EQ (e.g., “Alexa, turn up the bass”), setting sound modes (e.g., “Alexa, set movie mode”), and switching inputs.

Spotlight: Denon HEOS

HEOS is a connected technology platform from Denon and Marantz, powering connected experiences across a multitude of Audio/Visual Receivers and stand-alone connected speakers. The included HEOS mobile application allows users to stream music from their favorite supported music service provider and synchronize the music across all of the user's HEOS-enabled devices.

HEOS built a combined Alexa Connected Speaker and Smart Home Skill to add voice control of streaming music, such as Pandora, TuneIn, and others, and device control capabilities, such as power on/off and input switching, on a user's HEOS device. Once a user enables the HEOS Home Entertainment Skill and completes device discovery, they can ask any Alexa built-in or Echo family devices in their Alexa account to start streaming music on their preferred HEOS device or pre-established HEOS group, skip to the next song (when allowed), raise/lower the volume, switch inputs on the device, and voice control many other functions.

When a user asks Alexa to perform a function on a HEOS device or pre-established HEOS group, Alexa passes the commands to the HEOS Connected Speaker Skill Lambda function as directives, and the HEOS skill lambda dispatches the directives to the HEOS cloud. Once the directive arrives, the HEOS cloud takes appropriate control actions on the targeted connected device. Both the cloud and the connected device generate related events to communicate play or control state information asynchronously back to the Alexa cloud. When users use the HEOS mobile application to initiate music stored on their phone or from other supported streaming providers, information about what is playing is communicated by events to the Alexa cloud, keeping Alexa aware and in-sync with what is playing on the HEOS device. Since Alexa is aware of what HEOS is playing, users can still ask Alexa what's playing, and they can control the music with commands like next, pause and resume, even though the HEOS cloud initiated and controls the music source.

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 SkillVideo 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.
