As of this writing, Amazon has thousands of sources for flash briefings. The sources they include can be hyper-local like your local news station. Amazon also has specific topics like tech or business, or general info. Many of these sources, like NPR, are podcasts provided by Tune-In. These briefings are audio files Alexa plays for you. Other sources like the AP news stories are read in Alexa’s voice. I wish Amazon told you which ones were audio files because her voice drones on after a while. I hope I get to change her voice like I can with Siri. Right now, you can just change the language to the English (UK) or German.
If you think you’d like a briefing in the future, but not now, just toggle it off. If you want to permanently disable a Flash Briefing skill, you’ll need to head over to the Skills section in the app and then tap Your Skills. Find the skill you want to disable and then tap Disable Skill. You don’t delete the skill, which makes sense since nothing installs on your Alexa device.
The Capital One skill allows you to check your credit card balance or make a payment when one is due. This is secure: The skill performs security checks and requires you sign in using your username and password. Then, when you open the skill, you must provide a four-digit code to confirm your identity. Just be wary of who is around when using the skill -- anyone who overhears you say your personal key can access your banking or credit card info just by asking Alexa.
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.
