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. 

Because Amazon opened up the development of Alexa Skills to anyone with the free Alexa Skills Kit (ASK) in 2015, anyone can create an Alexa Skill. As Alexa uses Natural Language Programing (NLP), those looking to build a skill don't need to worry about complex speech recognition. The ASK tools also makes it easier for novices to work with sophisticated NLP ideas.
This shouldn't scare you away, however. Alexa-enabled devices are great to have in your home and, with a little tweaking, can prove to be very good companions. I’ve hand-picked some of the most useful and unique Alexa skills from the thousands that are out there. Many of these skills will not be enabled by default, so you may need to follow the proper activation steps before using each one for the first time. 
One of my favorite features of Amazon’s voice controlled speakers, the Echo and Echo Dot, is the Alexa News Flash skill. Out of the box, it plays you a quick news briefing from standard news sources. What you probably didn’t know however was that you can customize your Alexa Flash Briefing with literally thousands of skills, tailored perfectly to the news you want. Here’s how it all works and how to set it up.

Now you’re ready to set up your flash briefing feed. First, type in a custom error message, which can be up to 100 characters. Alexa will say this text to the user if the skill fails to deliver the content. For instance, you might say something like, “[Skill name] is not available at the moment.” To hear a preview of Alexa saying your error message, click the Play button on the right.

Note: Your Flash Briefing settings apply to all Alexa devices registered to your Amazon account, and all users in your home get access to the same Flash Briefing content. However, if you or anyone in your home has a voice profile, Flash Briefing automatically skips stories and news items you've already heard. To learn more, go to About Alexa Voice Profiles.
The first of the Alexa flash briefing options to include is an error message. Alexa will read this to your audience if your briefing is unavailable. Next, you’ll be asked to paste the RSS feed provided by your audio host. The “preamble” field is a short, introductory cue that Alexa will read before delivering your briefing. Finally, fill out any remaining Alexa flash briefing options — frequency, briefing name, category/genre and more — and soon you’ll be ready to launch.
If you have an audience that cares about what you and you have content that you would like to share with that audience, Alexa Flash Briefing is an ideal way to engage with that audience. Whether you are posting your Flash Briefing hourly, daily, weekly, biweekly, or some other frequency, enabling your audience to add your content to their Flash Briefing is an easy way to become part of someone’s routine. Examples of Alexa Flash Briefing content would be updates from experts (health news, stock tips, political campaign news). See below for a more extensive list of examples. But the sky is the limit. If you have something to say and you have people who would love to hear from you, and hear your speak the content in your voice, Flash Briefing is ideal.
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."
The next step in our Alexa flash briefing tutorial is to set up an Alexa skill for delivering the briefing. First, visit the Amazon Developer Console to create a new skill. Begin by giving it a name, then click “next.” You’ll be offered a selection of Alexa skill models to choose from. Select “flash briefing” from the list, then you’ll be met with a series of Alexa flash briefing options.
