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.
Like all AI devices that use National Language Processing or NLP, Alexa does not understand all voices easily. But she learns to understand her people over time. She does, however, require people to speak in simple terms, with appropriate pauses, and use specific word orders. There are many times when she will say "I'm sorry, I don't know the answer to that question." More than likely, she doesn't recognize a word order or misunderstood the question.
