There is a brief introduction to Alexa on page 4 of the manual. Amazon Alexa is built in the cloud, so it is always getting smarter. The more you use Alexa, the more it adapts to your speech patterns, vocabulary, and preferences with new features continually being added. Ask Alexa to answer questions, play music, hear the news, get weather and traffic reports, control your smart home, and more.
There is also an Amazon Alexa quick start guide that is included with the Safe & Sound. This is titled “Get Started with Alexa” and explains how you can talk to Alexa through the Onelink Safe & Sound, how to download the Alexa app, and other basic Alexa functionality.
