      Alexa For Dummies - Paul McFedries

      Introduction

      Okay, I know just what you’re thinking: Why, oh, why would someone write a book about Alexa, Amazon’s famous and wildly popular virtual assistant? After all, don’t you just plug in an Echo or any of the umpteen other devices that come with Alexa built in, say, Alexa, and then ask a question or give a command? What else does a person need to know, for pity’s sake? I’m surprised Alexa requires even three pages of explanation, so how can this book have hundreds?

      First, wow, you ask a lot of questions. Second, well, you’d be surprised. Sure, Alexa’s basics are readily understood. That’s part of the beauty of Alexa and the devices that run it: The initial learning curve is pretty much a horizontal line.

      Ah, but Alexa is way deeper and more powerful than those out-of-the-box basics would indicate. You have a serious piece of software at your beck and call. (Well, your call, anyway; Alexa does not yet respond to becks.) I’m talking high-end artificial intelligence (AI), world-class voice recognition, and tons of third-party extensions. All that adds up to an amazingly sophisticated app that contains hidden depths just waiting for you to find them.

      About This Book

      Alexa For Dummies, 2nd Edition not only takes you on a complete tour of Alexa’s capabilities, tools, settings, and skills but is also fully updated to cover all the latest Alexa devices and features. You’ll even see that Alexa has a hidden whimsical side that it’s just dying to show. In the end, you’ll discover everything you need to know to get the most out of your Alexa investment. Best of all, you’ll have a ton of fun as you go along.

      This book boasts 15 chapters, but just because they appear sequentially, that doesn’t mean you have to read them that way. Use the table of contents or index to find the information you need — and dip into and out of the book when you have a question about Alexa.

      If your time is limited, you can also ignore anything marked by the Technical Stuff icon or the information in sidebars (the gray-shaded boxes). Yes, these tidbits are fascinating, but they aren’t critical to the subject at hand, so you won’t miss anything critical by skipping them.

      Within this book, you may note that some web addresses break across two lines of text. If you’re reading this book in print and want to visit one of these web pages, just key in the web address exactly as it’s noted in the text, as though the line break doesn’t exist. If you’re reading this as an ebook, you’ve got it easy — just click the web address to be taken directly to the web page.

      Finally, throughout this book, when you see an italicized word in a command to Alexa, that’s a placeholder. That is, you replace the italicized word with something else specific to your command. For example, the placeholder title means you replace title with the actual title of something (such as a song or an album).

      Foolish Assumptions

      This book is for people who are new (or relatively new) to using the Alexa voice-activated virtual assistant. Therefore, I do not assume that you’re an Alexa expert, an Alexa maven, or an Alexa aficionado. However, I do assume the following:

      You know how to plug in and connect devices.

      You have a running Wi-Fi network with an Internet connection.

      You know the password for your Wi-Fi network.

      You have either an iOS or an Android mobile device (that is, a smartphone or tablet).

      You know how to install and operate apps on your mobile device.

      Icons Used in This Book

      Like other books in the For Dummies series, this book uses icons, or little pictures in the margin, to flag things that don’t quite fit into the flow of the chapter discussion. Here are the icons that I use:

      Remember This icon marks text that contains something useful or important enough that you’d do well to store the text somewhere safe in your memory for later recall.

      Technicalstuff This icon marks text that contains some for-nerds-only technical details or explanations that you’re free to skip.

      Tip This icon marks shortcuts or easier ways to do things, which I hope will make your life — or, at least, the Alexa portion of your life — more efficient.

      Warning This icon marks text that contains a friendly but unusually insistent reminder to avoid doing something. You have been warned.

      Beyond the Book

      In addition to what you’re reading right now, this product also comes with a free access-anywhere cheat sheet that includes ten must-do setup tasks, 50 of Alexa’s most useful voice commands, and 50 of Alexa’s most fun voice commands. To get this cheat sheet, go to www.dummies.com and type Alexa For Dummies Cheat Sheet in the Search box.

      Where to Go from Here

      If you’ve had Alexa for a while and you’re familiar with the basics, you can probably get away with skipping the first three chapters and then diving in to any part of the book that tickles your curiosity bone. (Or, why not take advantage of your handy personal assistant? Just say, Alexa, give me a number between 4 and 15.) The chapters all present their Alexa know-how in readily digestible, bite-size tidbits, so feel free to graze your way through the book.

      However, if you and Alexa haven’t met yet — particularly if you’re not sure what Alexa even does — this book has you covered. To get your relationship with Alexa off to a fine start, I highly recommend reading the first three chapters to get some of the basics down cold. From there, you can branch out anywhere you like, safe in the knowledge that you have some survival skills to fall back on!

      Part 1

      Getting Started with Alexa

      IN THIS PART …

      Find out what Alexa is, what Alexa can do, and what hardware you need to use Alexa.

      Welcome Alexa into your home by learning where to put your Alexa device, getting your device on your network, and customizing Alexa.

      Discover some crucial basics about your Echo device and Alexa itself, as well as some important Alexa commands.

      Chapter 1

      Getting to Know Alexa

      IN THIS CHAPTER

      Bullet Learning about Alexa

      Bullet Seeing where you can buy Alexa

      Bullet Looking at Amazon’s Echo devices

      Bullet Figuring out which Alexa device is best for you

      Bullet Reviewing what you can do with Alexa

      An old proverb tells us that Well begun is half done. That is, if you begin a project in the best way you can, you'll have made such a good start that it'll seem like you're already halfway to your goal. In this chapter, you begin your relationship with Alexa well by learning some useful, perhaps even interesting, background about Alexa, including an answer to what might be the most important question of all: Just what is Alexa, anyway? (Or should that be just who is Alexa?)

      To get your Alexa education off to a solid start, this chapter takes you on an exploratory tour of the Alexa landscape. This is big-picture stuff where you learn not only what Alexa is but also where you can get Alexa and how to figure out which Alexa-friendly device you need. After taking you through these what, where, and how fundamentals, you also investigate what is likely the second most important question: Why would people even need Alexa in their lives?

      What Is This Alexa That Everyone’s Talking About (or, Really, To)?

      Okay, let me get right to it: Amazon Alexa is a voice service, a cloud-based software program that acts as a voice-controlled virtual personal assistant. In a nutshell, you use your voice to ask Alexa a question or give Alexa a command, and it dutifully answers you (assuming an answer exists) or carries out your request (assuming your request is possible). The key here is that Alexa responds to voice commands.

      In the movie Star Trek IV: Voyage Home, the crew of the Starship Enterprise travel back in time 300 years to 1986. In a memorable scene, Scotty, the ship’s chief engineer, goes up to a mid-’80s-era PC and says, Computer! When the machine doesn’t respond, he says, Computer! once again. He’s then handed a mouse and, thinking it’s a microphone, says, Hello, computer! Apparently, in the year 2286, interacting with a computer using anything but voice commands is unthinkable.

      We’re a long way from the voice-only future envisioned in Star Trek (and countless other sci-fi stories; remember voice-controlled HAL in 2001: A Space Odyssey?). However, as we sit here near the end of the second decade of the 21st century, you can feel the computer-interaction landscape starting to shift. After some 40 years of folks sitting in front of their PCs, typing away in near-total silence (with only the occasional wail of exasperation or groan of impatience to break the quiet), users are starting to find their voices.

      True, operating systems such as Windows and macOS have had voice-control tools for many years, but they were obscure and unreliable and used by only a handful of people. Voice control’s bid for the mainstream didn’t get serious until Apple purchased the Siri speech-recognition app in 2010 and released it with iOS 5 a year later. Suddenly, it became cool to interact with a computer (at least one in the shape of a smartphone) by using voice commands.

      Since then, numerous voice-control tools have been released, including Google’s Assistant, Microsoft’s Cortana, and various voice-command features found in modern cars. But it was the release of the full version of Amazon’s Alexa in 2015 that really got the voice ball rolling. Amazon doesn’t share sales figures, but most industry know-it-alls agree that at least two hundred million Alexa devices have been sold.

      Meet your new assistant

      Why is Alexa so popular? There are lots of reasons, but the one that matters is that Alexa is (or tries hard to be) a personal assistant. Older voice-command tools were geared toward using a computer: running programs, pulling down menus, accessing settings, and so on. Alexa doesn’t do any of that. Instead, it’s focused on doing things for you in your real life, including (but by no means limited to) the following:

      Playing music, podcasts, or audiobooks

      Setting timers and alarms

      Telling you the latest news, weather, or traffic

      Creating to-do lists and shopping lists

      Buying something from Amazon

      Controlling home-automation devices such as lights and thermostats

      Telling jokes

      That last one may be a bit surprising, but perhaps the second-most important reason behind’s Alexa’s success is that it comes with whimsy as a feature. Alexa, as I hope to show in this book, is both useful and fun.

      Remember Older and lesser voice-controlled systems recognize only a limited set of commands that have to be enunciated precisely, so using such systems feels stilted and slow. Alexa, by contrast, is an example of a new breed of voice-aware systems that use conversational artificial intelligence. That term sounds pretty geeky, but it simply means that Alexa isn’t meant to be controlled so much as interacted with. With Alexa, you ask your questions and give your commands using natural language and your normal voice. Does it work perfectly every time? Nope, we’re not in Star Trek territory just yet, but I think you’ll be pleasantly surprised at just how well it does work.

      Alexa’s components

      Throughout this book I talk about Alexa as though it’s a single object, but Alexa is actually a large collection of objects that, together, create the full, seamless Alexa experience. I talk about many of these objects — particularly the Alexa app — throughout this book. From the behind-the-scenes perspective, however, all you need to know for now is that Alexa consists of the following four components:

      Name recognition: When you interact with Alexa, it seems as though the device understands what you say, but the only speech your Alexa device recognizes is the word Alexa, which Amazon calls the wake word. That is, it’s the word that lets Alexa know it should wake up and start listening for an incoming command or question. (In case you’re wondering: Yep, you can change the wake word to something else. I show you how to do that in Chapter 15.)

      Speech recording: Your Alexa device has one or more built-in microphones that capture the questions, commands, requests, and other utterances that you direct to the device. A simple computer inside records what you say and then sends the recording over the Internet to the Alexa Voice Service (discussed next). This part of Alexa is sometimes called the voice user interface (VUI).

      Alexa Voice Service (AVS): Here’s where the real Alexa magic happens. This part of Alexa resides in Amazon’s cloud. AVS takes the recording that contains your voice command and uses some fancy-schmancy speech recognition to tease out the words you spoke. AVS then uses natural-language processing to analyze the meaning of your command, from which it produces a result.

      Speech synthesis: This component takes the results provided by AVS and renders them as speech, which it stores in an audio file. That file is returned and played through the Alexa device’s built-in or connected speakers.

      Technicalstuff WHAT’S ALL THIS ABOUT A CLOUD?

      I’ve mentioned the term cloud a couple of times now, so let me take a few minutes of your precious time to explain what I’m talking about. In many network diagrams, the designer is most interested in the devices that connect to the network, not the network itself. After all, the details of what happens inside the network to shunt signals from source to destination are often complex and convoluted, so all those minutiae would only detract from the network diagram’s larger message of showing which devices can connect to the network, how they connect, and their network entry and exit points.

      When designers of a network flowchart want to show the network but not any of its details, they almost always abstract the network by displaying it as a cloud symbol. (It is, if you will, the yadda yadda yadda of network diagrams.) At first the cloud symbol represented the workings of a single network, but in recent years it has come to represent the Internet (the network of networks).

      So far, so good. Earlier in this millennium, some folks had the bright idea that instead of storing files on local computers, they could be stored on a server connected to the Internet, which meant that anyone with the right credentials could access the files from anywhere in the world. Eventually, folks started storing programs on Internet servers, too, and started telling anyone who’d listen that these files and applications resided in the cloud (meaning on a server — or, more typically, a large collection of servers that reside in a special building called a data center — accessible via the Internet).

      One such application is Alexa Voice Service, which resides inside Amazon’s cloud service called Amazon Web Services (AWS). So, that’s why I say that Alexa is a cloud-based voice service. That’s also why you need an Internet connection to use Alexa: It requires that connection to access its cloud component.

      How Alexa works

      Given the various Alexa components that I outline in the preceding section, here’s the general procedure that happens when you interact with Alexa to get something done:

      You say Alexa.

      Your Alexa device wakes up, as indicated (in most cases) by the device’s light ring turning blue. (See Chapter 3 for more about the light ring.) The device is now hanging on your every word.

      You state your business: a question, a command, or whatever.

      The Alexa device records what you say. When you’re done, the device uses your Internet-connected Wi-Fi network to send the recording to AVS in Amazon’s cloud.

      Warning It may seem as though Alexa lives inside whatever device you have, but Alexa is an Internet-based service. If you don’t have Internet access, you don’t have Alexa access either.

      AVS uses its speech-recognition component to turn the recorded words into data that can be analyzed.

      AVS uses its natural-language processing component to analyze the words in your command and then try to figure out exactly what you asked Alexa to do.

      AVS doesn’t analyze every single word you say. Instead, it’s mostly looking for the telltale keywords that indicate what you’ve asked Alexa to provide. For example, if you said What’s the weather forecast for tomorrow?, all AVS needs are the words weather, forecast, and tomorrow to deliver the correct info.

      If AVS can’t fulfill your request directly, it passes the request along to a third-party service (such as AccuWeather or Wikipedia), and then gathers the response.

      AVS returns the response via the Internet to your Alexa device.

      What AVS returns to your Alexa device depends on the result. If the result is just information for you, AVS passes along the text and also converts the text to speech and stores the speech in an audio file that your Alexa device can play. If the result is a command (for example, to play a particular song), AVS passes that command back to the Alexa device.

      The Alexa device either uses its built-in or connected speaker to broadcast the result of your request or carries out your command and lets you know what it did.

      If your Alexa device has a screen, you also see the result on the screen.

      Where Do You Get Alexa?

      In most cases, Alexa is closely associated with hardware devices, and how close that association is depends on the device. There are three types of devices to consider:

      Devices that have Alexa built in: As you might have expected, Amazon offers a huge range of products that have Alexa inside, including the Echo, Echo Dot, Echo Plus, Echo Spot, Echo Show, Fire tablet, and Fire TV. In addition, a massive ecosystem of third-party devices are Alexa-enabled, including select Windows PCs, sound systems, TVs, tablets, appliances, GPS units, and even car models.

      Devices that Alexa can control directly: Many devices are Alexa-friendly, meaning that Alexa can connect to and control those devices directly using either a Bluetooth or Wi-Fi connection. For example, you can use Amazon’s Echo Show to connect to and control a smart-home device such as a thermostat. Similarly, you can use any Amazon Echo device to operate the AmazonBasics microwave (yes, that’s right: a microwave oven that you can control with your voice!).

      Devices that Alexa can control indirectly: Although as I write this some 100,000 devices fit into the previous two categories, that still leaves a huge number of Alexa-ignorant devices. However, in some cases you can still have limited control over even these devices. For example, you can connect any Amazon Echo device to an Amazon smart plug, which you can turn on and off using Alexa. So, when you plug a non-Alexa device (such as a lamp) into the smart plug, you can use Alexa to turn that device on and off.

      Note that, at the start of this section, I said, in most cases. What are the exceptions? As I talk about in Chapter 2, Amazon offers the Alexa app, which is a program that you install on your smartphone or tablet. You can use the app to connect with and manage smart-home devices, but if you just want the standard Alexa experience — that is, using voice commands to ask questions and make requests — you can do all that directly from the app; no external hardware (such as the devices I ramble on about in the next section) is required.

      Figuring Out Which Alexa Device You Need

      In the preceding section, I mention that, with the exception of using Alexa on your phone or tablet, you can’t do the Alexa thing until you get a device that’s Alexa-enabled. That sounds straightforward enough, but that illusion of simplicity is shattered when you see the sheer number of available devices — and I’m not even talking about all the third-party Alexa devices. Amazon alone offers well over a dozen different Alexa-enabled devices just in its Echo brand of smart speakers. How are you supposed to know which one to get?

      Checking out Amazon’s Echo devices

      To help you make the right Alexa decision, this section offers a quick look at what’s available from Amazon’s Echo brand.

      Echo

      Echo (the fourth generation is shown in Figure 1-1) is your garden-variety Echo smart speaker designed for larger rooms because it comes with three speakers: a 3-inch woofer and two 0.8-inch tweeters. It’s fairly big — 5.7 inches in diameter and 5.2 inches high — so you may need to clear a spot for it. The fourth generation of the Echo comes with a built-in smart-home hub.

      FIGURE 1-1: Amazon’s Echo smart speaker.

      Echo Dot

      The Echo Dot is a smart speaker designed for smaller rooms because it comes with a single speaker. It's quite a bit teensier overall than the Echo (about 3.9 inches in diameter and about 3.5 inches high). It’s also half the price of the Echo, which is likely why it’s Amazon’s bestselling Alexa device. Some models of the fourth generation Echo Dot also come with a built-in clock, as shown in Figure 1-2.

      Photo depicts Amazon’s Echo Dot smart speaker.

      FIGURE 1-2: Amazon’s Echo Dot smart speaker.

      Echo Studio

      Echo Studio (shown in Figure 1-3) is the smart speaker designed for audiophiles thanks to its support of several high-end audio formats (including Dolby Atmos) and five — yep, you read that right: five — speakers: a 5.3-inch woofer, a 1-inch tweeter, and three 2-inch midrange speakers. It’s the biggest Echo at 6.9 inches in diameter and 8.1 inches high, so it won't go unnoticed. Echo Studio also comes with a built-in smart-home hub.

      Echo Flex

      The Echo Flex (shown in Figure 1-4) is a smart speaker that plugs directly into an electrical outlet. The Echo Flex comes with a single speaker (so it's not suitable for music playback) and is 2.6 inches wide and 2.8 inches high. Yep, that's tiny, but Echo Flex has a USB port that you can use to charge your USB devices or connect accessories such as a night light or a motion sensor.
