Amazon wants to bring Alexa to more devices than smart speakers, Fire TV and various other consumer electronics for the home, like alarm clocks. The company yesterday announced developer tools that would allow Alexa to be used in microwave ovens, for example – so you could just tell the oven what to do. Today, Amazon is rolling out a new set of developer tools, including one called the “Alexa Mobile Accessory Kit,” that would allow Alexa to work Bluetooth products in the wearable space, like headphones, smartwatches, fitness trackers, other audio devices, and more.

This kit is already being used by several companies, including device makers and solution providers Bose, Jabra, iHome, Linkplay, Sugr, Librewireless, Beyerdynamic, Bowers and Wilkins.
