Amazon recently announced its voice assistant built in its echo speakers for the hospitality industry. Marriott hotels USA is going to be the front runner implementing this technology in their hotels.
This is possibly the first significant use case for Alexa that I have heard since its launch. For one, Alexa is redundant with Siri and ogle assistants built in our modern smartphones.
Hope Amazon can come up with more relevant use cases for Alexa in the near future!
