If you want to do some casual research for a future trip, you can get fare estimates using the Kayak skill. You can say, "Alexa, ask Kayak where I can go for $400" or "Alexa, ask Kayak how much it costs to fly from Los Angeles to Dublin." The skill will ask for additional information and eventually provide you with a series of options and price ranges.
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."
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.
If you think you’d like a briefing in the future, but not now, just toggle it off. If you want to permanently disable a Flash Briefing skill, you’ll need to head over to the Skills section in the app and then tap Your Skills. Find the skill you want to disable and then tap Disable Skill. You don’t delete the skill, which makes sense since nothing installs on your Alexa device.
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.
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.
