Microsoft Readies Its Answer to Siri: 'Cortana'

Microsoft is reportedly readying its answer to Siri and Google Now: Cortana. Named after a central character in the game Halo, Cortana aims to go beyond both Siri and Google Now by being a more comprehensive way to interact with Microsoft devices.

According to Microsoft watcher Mary Jo Foley:

Cortana, Microsoft's assistant technology, likewise will be able to learn and adapt, relying on machine-learning technology and the "Satori" knowledge repository powering Bing.

Cortana will be more than just an app that lets users interact with their phones more naturally using voice commands. Cortana is core to the makeover of the entire "shell" -- the core services and experience -- of the future versions of Windows Phone, Windows and the Xbox One operating systems, from what I've heard from my contacts.

A comprehensive personal assistant powered by AI across all Microsoft systems and devices is a very ambitious plan. It remains to be seen whether Microsoft can do it. 

Yet in order to not be perceived as more than a me-too product Microsoft will have to roll out something truly impressive and more utilitarian than Siri or Google's mix of voice-enabled search and personalized data features.
