Alexa, it's time for work: Ask Cortana to read Outlook emails

The two archrivals in the field of cloud computing are partnering so their voice-controlled assistants can talk to one another. Amazon currently dominates the market it created. Alexa and Cortana will be going to the dance together. On Wednesday, Amazon and Microsoft announced a first-of-its kind collaboration between the one-time rival digital assistants that will begin in earnest later this year. Owners of Amazon's popular Alexa-driven Echo speakers will be able to say, "Alexa, open Cortana."
