Amazon's VP of Alexa explains what's next for the company's smart personal assistant

In the Game of Thrones-like artificial intelligence competition between Houses Amazon, Apple, Facebook, Google, and Microsoft, the company most reticent to speak about its technology has usually been the one that ships planeloads full of stuff to consumers, hosts thousands of companies in its data centers, greenlit Catastrophe, and has a breakaway hit product that answers questions, plays music, and 4,998 or so other things. Yes, for some time, Amazon has been even more shrouded than the famously secret Apple, which opened up about its machine learning programs earlier this year. Lately, however, Amazon's head scientist and vice president of Alexa, Rohit Prasad, has been speaking up in public, making the case for his company's prowess in voice recognition and natural language understanding. Alexa, of course, is the conversational platform that supports that aforementioned hit product, Echo. On Wednesday Prasad gave an Alexa "State of the Union" address at the Amazon Web Services conference in Las Vegas, announcing an improved version of the Alexa Skills Kit, which helps developers create the equivalent of apps for the platform; a beefed-up Alexa Voice Service, which will make it easier to transform third-party devices like refrigerators and cars into Alexa bots; a partnership with Intel; and the Alexa Accelerator that, with the startup incubator Techstars, will run a 13-week program to help newcomers build Alexa skills.
