Microsoft unveils voice assistant Cortana to rival Apple's SiriSAN FRANCISCO - Microsoft Corp on Wednesday formally announced it has developed a voice activated phone assistant feature called Cortana, a direct rival to Apple Inc's Siri.
The feature has been rumored for some months and a test version was demonstrated by Joe Belfiore, a Windows Phone executive, at Microsoft's annual developer conference in San Francisco.
The Cortana service, which can take verbal instructions to search the Web, set alarms, make calls and a host of other actions, is still in beta testing, said Belfiore, but will soon be a standard feature on Windows phones.
Belfiore announced that the latest version of Microsoft's smartphone software, called Windows Phone 8.1, will be rolled out to consumers as a downloadable upgrade in the next few months, and new phones running the software will be in stores by late April or early May.
