Microsoft Corp. and Amazon.com Inc. may be competing with each other in the cloud-computing market, but in the realm of voice-controlled personal assistants, Cortana and Alexa are forging a friendship.
On Monday, the two companies showed the fruits of a collaboration announced last August to let Amazon’s Alexa and Microsoft’s Cortana talk to each other. In a demonstration, Cortana executive Megan Saunders used Alexa to order milk and then had the assistant wake Cortana to check her schedule and send email.
