Amazon wants to see Alexa inside the next generation of smart watches and headphones. To make that happen, the company announced plans this morning for a “mobile accessory” development kit, which is supposed to make it easy for hardware companies to build Alexa into their wearable products. Amazon says it will allow them to “add Alexa to their devices with minimum investment in hardware or integration efforts.”

This won’t mark the first time Alexa has made it to headphones or watches — companies have tried this in the past — but it’s been rare. The promise here is that products using the toolkit should theoretically work better, too, since Amazon is handling the bulk of the integration.
