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.
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.
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.
