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.
Google Assistant doesn’t have flash briefings in the Alexa sense — instead, you’ll be publishing your audio content as a podcast. This is a little more technical than Alexa’s process. First, your briefing will need its own homepage. Second, you’ll need to edit the briefing’s RSS feed to include snippets of code that are required for Google Assistant to recognize it in its directory — check out all the requirements here. Google doesn’t require setting up an Assistant action. Once you’ve included the necessary code in your RSS feed, your podcast will show up automatically within search results.
For tracking your food, you can use the Track by Nutritionix skill, which lets you record your food intake using your voice, or ask for caloric values of foods. (Alexa does the latter by default.) Say things like, "Alexa, tell Food Tracker to log a cup of almond milk" or "Alexa, ask Food Tracker how many calories are in two eggs and three slices of bacon."
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.
Alexa Skills can give users access to accounts they've already set-up, such as the Alexa Skill for SiriusXM radio, ESPN, or even their car insurance if they have Alliance Insurance. With Alexa connected to these accounts, people can pull up details and content through their Alexa-enabled device. For example, the Alexa Skill for Major League Baseball lets Alexa users stay current with baseball stats and hear shows. Use the Alexa Skill for Fandango to not just find a movie but buy a ticket.
How does Alexa work? Once you buy an Amazon Alexa device — Amazon Tap or an Echo Dot — the device connects through WiFi or Bluetooth to the internet and then to other devices. With the most common devices, the Amazon Echo and Echo Dot, people merely say "Alexa," which wakes up the device, and then ask for what they want. Alexa Skills radically expands the bots repertoire, allowing users to perform more actions with voice-activated control through Alexa.
