Amazon's Alexa has become the flag-bearer for AI assistants. Not only does she possess an exhaustive list of useful skills, but she's also started finding new homes in everything from phones to cars, watches, little robots and even refrigerators. There's a reason Amazon's Echo and Echo Dot speakers are particularly suited for ordering Alexa around at home, though. They both feature a fancy far-field, seven-microphone setup and audio processing smarts that help Alexa understand your muffled commands shouted from the downstairs bathroom. Today, Amazon's announced it's releasing this mixture of hardware and software in a new development kit, so other companies can build Alexa prisons that recognize you want to add mixed spices to your shopping list, and not listen to a Spice Girls mix (liar).
