For tracking your food, you can use the Track by Nutritionix skill, which lets you record your food intake using your voice, or ask for caloric values of foods. (Alexa does the latter by default.) Say things like, "Alexa, tell Food Tracker to log a cup of almond milk" or "Alexa, ask Food Tracker how many calories are in two eggs and three slices of bacon."
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.
In the Alexa app, this is achieved by selecting the main menu button (found in the upper left-hand corner of the screen) and choosing the Skills option. From here you can browse Alexa skills by category or other criteria such as those favored the most by its large user base. You can also search for skills by keyword or name through this same interface.
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.
Many Alexa Skills are tailored for news and information. Alexa's Flash Briefing, a quick update of top headlines, can be pulled from a preferred media source: Fox News, NPR, The Wall Street Journal, and The Daily Show are just a few options. Users can also check train or bus schedules, check for someplace to eat through Restaurant Finder, check the traffic, or find a select store's hours.
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.
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."
Starbucks lets you place an order using Alexa with the Starbucks Reorder skill. After you enable the skill, you will need to link your account. The skill will not work unless you've previously placed a mobile order with the Starbucks app on Android or iOS. It can place an order at one of the last 10 Starbucks locations you've visited in person. You can also check your account balance and switch between your five previous mobile orders.
You can create a flash briefing skill if you own, or have the right to distribute, original text or audio content that updates frequently. You should understand web technologies and have the ability to configure HTTPS, RSS and/or JSON content. The voice interactions for a flash briefing skill are defined by Amazon, but you must be able edit the format of your content so that the flash briefing Skill API can understand it.
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.
