Alexa, the voice assistant in Amazon's Echo devices, has its first celebrity voice! Oprah becomes the first celebrity to collaborate with Amazon, but it's only for a special holiday shopping promotion. The collaboration will see Alexa customers shop her “Favorite Things.” Echo owners must say "Alexa, let’s shop Oprah’s favorite things.” Oprah will then give an explanation on why she picked the item this year. There are 102 products on Oprah’s list, like a Samsung TV or lipstick. Are you ready to go shopping with Oprah?
