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."
Alexa Skills themselves are quite helpful. However, even with an updated Skills section in the Alexa app and the ability to add skills using only your voice, discovering new and useful skills is a less than desirable experience. So much so that Amazon actually created a skill called Skill Finder which, you guessed it, helps you discover new skills. Launch it by saying, "Alexa, open Skill Finder" or "Alexa, tell Skill Finder to give me the skill of the day."
How does Alexa work? Once you buy an Amazon Alexa device — Amazon Tap or an Echo Dot — the device connects through WiFi or Bluetooth to the internet and then to other devices. With the most common devices, the Amazon Echo and Echo Dot, people merely say "Alexa," which wakes up the device, and then ask for what they want. Alexa Skills radically expands the bots repertoire, allowing users to perform more actions with voice-activated control through Alexa.
