[MUSIC] So one of Google Home's cool features is its ability to use the context from your previous question, to answer the next question. But Alexa can do that to an extent, too. Alexa, what's the weather? Right now. So I asked the follow-up question, I'm not even going to say the word weather. Alexa. How about Friday? Here's the forecast for Friday. And she infers the weather. Now, Google Home can take it a step further. Alexa. Stop. Hey, Google. Who plays Luke Skywalker? Mark Hamill plays Luke Skywalker. And I'll just use pronouns on the follow-up. Hey, Google. What other movies is he in? Star Wars, Episode Seven, The Force Awakens. Star Wars [CROSSTALK] So Google takes a step, but only a step beyond what Alexa can do.
