Microsoft is preparing a Siri-like personal voice assistant based on Bing, code-named Cortana, for Windows Phone,  eWeek reports. (Cortana is a holographic AI construct that figures prominently in the Halo video game series.)

Like its Halo counterpart, Cortana “will be able to learn and adapt, thanks to machine-learning technology and the ‘Satori’ knowledge repository powering Bing,” according to ZDNet’s Mary Jane Foley.

Satori, which means “understanding” in Japanese, anchors Bing Snapshot, a feature that enhances search results by delivering in-context facts and associated content that is pulled from Wikipedia and social media.

The technology will also influence a major portion of the Windows ecosystem, suggests Foley.
