There are millions of people who own multiple devices with Alexa built-in, and these customers want to be able to combine their speakers to create whole-home audio experiences. That’s why we created Alexa Multi-Room Music (MRM), which enables you to play music synchronized on multiple Alexa devices throughout your home. Tools are available for commercial device makers to integrate Alexa MRM into their products. In this video, David Frerichs, Principal Solutions Engineer with the Alexa Voice Service (AVS), provides details of MRM for device makers.
