We see a future where the service will know you: know your intent, your social and business connections, your likes and dislikes, your privacy preferences, and the things that define the context that’s important to you. The result will be a speech NUI service that helps you accomplish everyday tasks in a more natural and conversational manner. This service will simplify tasks that used to be tedious or impossible on a TV or other device, by combining an understanding of language and intent with a deep knowledge of you, the user. We envision a future where we build on the experiences we deliver today with Kinect for Xbox 360, Windows Phone, or Bing for iPad or iPhone apps, by enhancing the speech NUI experience to understand more layers of context: what you are doing, where you are doing it, the kinds of devices you are using and your historical preferences. Because this is a cloud-based service, your interactions will be able to persist over time, enabling you to pick up where you left off, regardless of what device you may be using. “
