Alexa, what can you do for me?

“Alexa, what time is it?” You’ve seen the commercials. Folks going about their daily lives, chatting with Amazon’s amicable virtual assistant.

It started in November of 2014, when Amazon branched out into a new space. It released the Echo, a cylindrical smart home speaker imbued with artificial intelligence. Dubbed Alexa, Amazon’s AI gained popularity in many households.

Nowadays, Amazon’s Alexa products are a common fixture in the tech news cycle. However, you still may not know all that much about her. Here are the details on how she works, a few of her tricks, and how she compares with other leading digital assistants out there.

What is Amazon Alexa?

Alexa is the name of Amazon’s voice-based smart home assistant. While some folks will use the names interchangeably, Alexa is actually the name of just the AI—not the product. You can use Alexa in Amazon’s Echo products. These now include the original Amazon Echo, the smaller Echo Dot, the Amazon Tap, the Echo Look, and the newest addition to the lineup, the Echo Show.

Once you’ve got an Echo device, you download the Alexa app on your phone to go along with it and complete setup.

Recently, Amazon also gave iPhone owners the ability to access Alexa without an Echo device, though. You can access her simply through the Amazon app.

Like Apple’s Siri in the U.S., Alexa has a female voice. She only responds when summoned, and you can talk to her using normal sentences.

How does Alexa work?

By default, Echo devices use “Alexa” as their wake word. While the device is constantly listening, it only starts tracking and analyzing what you say next after it hears “Alexa.” It then pulls up the relevant results. However, if, say, someone in your house is already named Alexa, you can change the wake word to something else: Amazon, Echo, or Computer.

From there, you can ask Alexa all sorts of questions: You can ask her to play music, ask about the weather, or ask her to convert measurements for you. You can also use her to shop for products on Amazon or to control other smart home devices in your home. A number of third-party apps and services work with Alexa, so you can do things like order a Domino’s pizza, or ask for the latest Washington Post headlines. Amazon calls each of these different capabilities “skills.” One of her newest skills is the ability to work as an intercom system in your home.

There are also a number of hidden features and quirky questions-and-answers you can ask Alexa. For example, you can ask her to play Rock, Paper, Scissors; get responses when you quote favorite movies (“May the force be with you”); or use her to do math on your behalf.

Alexa’s Settings

You can customize a lot of what Alexa can do (beyond just changing her wake word) by heading into the app. In the menu on the left-hand side of the app, you can log into your favorite music (and video and e-book) sources, including Spotify and Pandora. You can add items to shopping or to-do lists, and manage alarms or reminders. And under Skills, you can download some of those third-party capabilities we mentioned above: adding an NPR flash briefing, downloading ambient rainforest sounds (apparently that’s a customer favorite this week), or add a game such as Jeopardy! or Word Reverse.

In the actual Settings section of this menu, you can customize your Alexa experience further. You can manage Amazon Shopping notifications, adjust what content you want in your daily flash briefing of the day’s headlines, and choose what sports teams you care about for your sports update. You can also enter in your home or work address to get traffic updates for your daily commute, and sync with your calendar (Gmail, Outlook, or iCloud) to know what’s up next on the day’s schedule.

If Alexa has trouble understanding your commands, you can go through a quick voice-training session to teach it how you speak. And if you’re wary that she might accidentally make purchases on your behalf, you can enable or disable voice purchasing, or add a four-digit confirmation code that you speak aloud to confirm purchases.

In the app’s settings, you can also see a history of all the voice interactions you’ve had with your Alexa. You can tap on any item in this list to hear the recording from that session. (Here, you can also delete recordings, too.)

How does Amazon Alexa stack up against the competition?

Is Alexa the home assistant of your dreams? It all depends on what you’re looking for.

Amazon Alexa vs. Siri

Until recently, Siri’s only been available on an iOS device, Mac, or (in limited form) through your Apple TV. However, in June, Apple debuted its true Amazon Echo home competitor: the HomePod. Unfortunately, if you want one now you’ll have to wait—it’s not shipping until December. Still, we can make some comparisons about the two lines of products, as well as how Alexa and Siri compare as disembodied virtual assistants.

Amazon Alexa vs Siri

Apple HomePod

Smart Home Control

Both devices work with a variety of smart home lights, thermostats, plugs, and more, but Amazon’s Echo definitely works with a greater range of brands and products. The key difference is that with Apple’s HomePod, the compatible devices need to be HomeKit-enabled, where Echo-compatible smart home products don’t (necessarily). If you’ve already got some connected home products installed, you can check and see which platform it’s compatible with.

Voice Recognition

From time to time, both Siri and Alexa slip up and don’t quite understand what you’re saying (or asking). On the whole though, in my experience using Siri on an iPhone and on an Apple TV compared to speaking to an Amazon Echo, Alexa typically does a better job of understanding the words coming out of my mouth.

For example, I tasked both AI’s with three questions: “What’s the temperature outside?”, “When do the Sharks play next?”, and “What movie should I see this weekend?” Amazon understood all three questions perfectly, while Siri thought the latter was “What movies with you this weekend.”


Response Accuracy

Now, just because Alexa understands what I’m saying better doesn’t mean she always has a response to my questions, though. Both AI’s gave me the current weather report, Alexa said she didn’t have information for the Sharks query, and Alexa also didn’t have a response for the movie question. Siri, however, gave me information about the Sharks’ next game (October 4, against the Flyers, if you’re curious), and for the movie question, while she didn’t hear it quite right, she still got the gist: She suggested seeing War for the Planet of the Apes on Friday, along with movie times at a handful of nearby theaters. Is Siri smarter? She may know a wee bit more than Alexa, but largely, their question-and-answer base is comparable.

Speaker Quality

These devices are first and foremost, a speaker. If you plan to use the device to play your favorite tunes on the regular, Apple’s HomePod may make more sense. In its WWDC keynote, Apple really played up the HomePod’s audio chops—and it’s more expensive price tag would also suggest that it’s got higher quality drivers and woofers inside. However, we have not tested this in person, so this is speculative (for now).


Both Siri and Alexa have a ton of so-called “Easter eggs”—funny or amusing hidden responses. Alexa has a growing list, and Siri’s funny questions always seem to be evolving. But if you’re looking not just for utility, but for entertainment value, Alexa may beat out Siri since some of her third-party skills include games.


HomePod will cost you $349 compared to $179.99 for an Amazon Echo.

Amazon Alexa vs. Google Home

Amazon may have been first with its speaker-based assistant, but Google followed in 2015 with its own take, Google Home.

Google Home

Smart Home Control

While Google Home is compatible with a wider array of smart home products than Siri is, it’s still not as many as Alexa can work with. However, depending on what’s already in your home, that may not be a big deal.

Voice Recognition

Both Google and Amazon excel at understanding what you’re asking. In fact, they can even understand one another—and become friends (whether that’s amazing or terrifying is up to you). In my experience hailing “OK Google” on an Android phone over the past few years though, Google may slightly edge out Amazon in this department.

Response Accuracy

Google and Amazon each have different strengths here. Google, naturally, has the ability to answer some pretty darn complex questions—it is Google, after all. Alexa does better with more simple queries. Amazon’s AI, thanks to its third-party skills, can actually respond (or act) on a wider variety of requests than you can with Google’s assistant, though. So if you want your smart speaker to be more of an actual assistant—performing tasks for you, ordering things on Amazon for you—Alexa is what you want.


Speaker Quality

Audio quality may be in the ear of the beholder. The Wirecutter thought the Amazon Echo just edged out Google Home; PCMag, however, preferred the tones of Google’s smart home speaker. Basically: Both are comparable in terms of quality. However, if you stream music on Apple Music, Soundcloud, or Google Play, you’ll want to go with a Google Home over an Echo.


Google may have a few “quirky” responses, but really, it’s all about business. If you want no-frills information and functionality, a Google Home may make more sense for you.


Normally, Google Home is cheaper than many Amazon Echo products: $129 for a Google Home, compared to $179.99 for an Amazon Echo. (You can still get a smaller Echo Dot for $49.99). However, at the time of writing, both products are on sale for under $100—$99 for the Google Home, and $89.99 for the Echo, respectively.
