After your kids are asleep, Alexa can help you doze off with the Ambient Noise skill and its companion skills. There are several different sounds to choose from, all of which come with their own skill. You can fall asleep to the sounds of a thunderstorm, rain, ocean, wind chimes, babbling brook, rain on a tent, city sounds and much more. For all available sounds, just say, "Alexa, ask Ambient Noise for a list."
Amazon's Alexa is the voice-activated, interactive AI bot, or personal assistant, that lets people speak with their Amazon Echo, Echo Dot and other Amazon smart home devices. Like Siri and Cortana, Alexa is designed to respond to a number of different commands and even converse with users. Alexa comes with more than a few capabilities: playing music, pulling up the weather or even reading news. But Alexa Skills are apps that give Alexa even more abilities, letting her speak to more devices even websites.
