Mary Jo Foley is reporting that Microsoft is in a process of testing Siri-like personal assistant, fittingly called Cortana from Halo. Cortana would be brought to Windows Phone 8.1 “Blue”. If you haven’t used Siri, the difference here to simple voice commands is that this gives wider range of commands and is able to learn and adapt.
The Verge has also acquire pictures of a early test version of Cortana on Windows Phone 8.1 and its “service-enabled shell”. It shows that Microsoft is certainly aiming Cortana to be quite a deep on features, and The Verge claims there should be even more on the final version.
