After your kids are asleep, Alexa can help you doze off with the Ambient Noise skill and its companion skills. There are several different sounds to choose from, all of which come with their own skill. You can fall asleep to the sounds of a thunderstorm, rain, ocean, wind chimes, babbling brook, rain on a tent, city sounds and much more. For all available sounds, just say, "Alexa, ask Ambient Noise for a list."

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.
