Microsoft's heavily rumored Siri-like personal digital assistant "Cortana" remains officially unannounced, but the evidence for its existence continues to mount.
UnleashThePhones.com has posted an extended video showing off what appears to be Cortana. It's the first time we've seen the service in action. Unfortunately, it lacks a speaking voice believed to be performed by none other than Cortana actor Jen Taylor.
Cortana is Microsoft's rival to Apple's Siri and Google Now. As gamers will no doubt know, it takes its name (or potentially code-name) from the holographic artificial intelligence character Cortana from the Halo series.
The Cortana service for Windows Phone will reportedly be able to learn and adapt, allowing it to address you by your name or a nickname. You'll also reportedly be able to ask Cortana to perform tasks for you like "wake me at 7 a.m." to set an alarm.
GameSpot sister site CNET reports that Cortana will be an opt-in service, so you won't have to use it if you don't want to. Unsurprisingly, you'll need a Microsoft Account to use Cortana, which will officially replace Bing, according to the report.
Cortana is expected to launch as part of Windows 8.1 in late March or early April. Support for other Microsoft devices like Windows computers and Xbox consoles could come later.
