Nick Wingfield, writing for the NYT:
Cortana is named after a virtual character in Halo,
Microsoft’s science-fiction video game series, that uses her
encyclopedic knowledge about the universe to help the game’s
protagonist, Master Chief. The actress, Jen Taylor, who does the
voice for the character, also provided recordings for the phone
Two things jumped out at me regarding this story. First, that Microsoft gladly credited the actress supplying Cortana’s voice. Second, that Google and Android went unmentioned in the article.
Update: More on Cortana from The Verge.
