Alexa for Speakers

A Full Alexa Experience for Connected Speakers

Device makers can provide a full Alexa experience in their connected speakers with Alexa built-in. Customers can talk to speakers to play music, listen to the news, set timers, conduct phone calls, and control smart home devices. With Alexa Multi-Room Music (MRM), Alexa built-in speakers can be grouped with other Echo family products and MRM-compatible third-party products for a whole-home music experience. Finally, customers can also use Alexa Cast to cast music to any Alexa built-in speaker from any Alexa Cast-compatible mobile app.

Spotlight: Harmon Kardon Allure

The Harman Kardon Allure is a premium connected speaker with Alexa built-in that combines industry leading sound design with a unique aesthetic that brings connected speakers to the centerpiece of any room in the connected home. The Allure features a 4-mic, far-field mic array and audio front end solution from Synaptics, one of Amazon’s certified third-party development kits, and Amazon’s wake word engine.

Harman Kardon also partnered with Linkplay, one of Amazon’s Solution Integrators, to design and implement a custom AVS device firmware built to Harman Kardon's specifications to accelerate their time-to-market. This approach allowed Harman Kardon to focus on designing an optimal acoustic experience for the device while delivering a top-notch Alexa implementation at an increased pace.

Harman Kardon certified their architecture for Amazon’s Multi-Room Music (MRM) time synchronization protocols and deployed a custom set of time synchronization libraries from Amazon to add MRM compatibility. Coming soon, the Harman Kardon Allure will add capabilities to participate in a group with any MRM-compatible and Echo family devices to synchronize music playback across many devices in multiple rooms.
