This shouldn't scare you away, however. Alexa-enabled devices are great to have in your home and, with a little tweaking, can prove to be very good companions. I’ve hand-picked some of the most useful and unique Alexa skills from the thousands that are out there. Many of these skills will not be enabled by default, so you may need to follow the proper activation steps before using each one for the first time.
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.
You'll notice in the lists below that many Alexa skills are called by using trigger words like open, start, play and ask. While select skills require you to use specific terms, others consider them to be interchangeable and will work with some or all of these phrases. Over time you'll begin launching your favorite skills by the words you feel most comfortable using. Initially, though, it can be fun to play around with each.
