In Microsoft’s first-person shooter “Halo,” the character Cortana is a female A.I. companion that guides you through the battlefield. In real life, she’s about to become Microsoft’s answer to Siri and Google Now. The Seattle software giant took to its 2014 Build conference to unveil its Cortana voice assistant, which will launch in beta alongside the Windows Phone 8.1 operating system. While it may sound very similar to its competition, Cortana does have some neat features exclusively for Windows Phone owners.
Cortana is powered by Bing, and the assistant uses your voice searches to store your preferences in categories like sports, food, travel and weather inside of her "notebook." This allows the app to give you more personalized results as you continue to use it.
