Warner Brothers created a choose-your-own-adventure game for Alexa called The Wayne Investigation, wherein you investigate the death of Bruce Wayne's parents, Thomas and Martha Wayne. Start the game by saying, "Alexa, open The Wayne Investigation" and follow the prompts. Each choice you make affects the outcome of the story. This is one of the best examples of a game style that suits Alexa perfectly.
When Alexa recognizes your voice, stories and news items you’ve already heard will be skipped. To set up voice recognition, say “Alexa, learn my voice.” This is feature is especially useful if you listen to flash briefings on weekends when many flash briefings don’t post new content. With Alexa voice recognition enabled, you won’t hear the flash briefing episodes you already listened to.
Amazon's Alexa-powered speakers are great for a lot of things beyond playing music or changing the color of your smart bulbs. Alexa can play audiobooks or read your Kindle books to you, if you don't have the audiobook version. It can give you the forecast, the latest tech news (with CNET!) or tell you if you should expect traffic on your way to work. And it can, of course, tell you a few jokes.
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.
