SEATTLE, March 3 (UPI) -- Microsoft's upcoming Windows Phone 8.1 update will replace its Bing search functionality with a new personal digital assistant called Cortana, according to The Verge.
Sources familiar with the development told the technology magazine that the new voice-activated personal assistant will be a circular animated icon rather than a female character like Siri. But Cortana will be similar to Siri in that it will develop a personality the more you speak to it.
