What is Amazon Alexa?
The brains behind many smart products, Amazon Alexa is the voice assistant that powers the Echo smart speakers, newer Fire TV devices and more. As Alexa runs in the cloud, the facilities it provides are largely the same across all devices. As such, this is a guide to Alexa, which will contain the latest updates and features as the technology progresses. Hardware reviews can be found elsewhere on the site. And, this guide shouldn’t be confused with the specific Amazon Echo guide – that looks in-depth at Amazon’s own-brand smart speakers and tells you the tips and tricks you can use to improve them.
Amazon Alexa – Which devices use the smart assistant?
Amazon Alexa features in a growing range of products, developed both by Amazon itself and numerous third parties. Alexa’s popularity looks set to grow, as more manufacturers look to integrate the smart assistant into their own speakers, tablets and more. Here’s the list of products that have Alexa built in that Trusted Reviews has already reviewed.
- Amazon Echo 2nd Generation
- Amazon Echo Dot (2nd Gen)
- Amazon Echo Dot (3rd Gen)
- Amazon Echo Plus
- Amazon Echo Plus (2nd Gen)
- Amazon Echo Show (2nd Gen)
- Amazon Echo Spot
- Amazon Echo Sub (not a standalone product, requires additional Echo devices)
- Sonos One

Amazon Alexa – A note on third-party speakers
There’s a growing number of third-party speakers with Amazon Alexa built in, giving you more choice. At the moment, that choice comes with some fairly hefty caveats that may put you off, as Amazon doesn’t open up the full Alexa abilities to all devices. For example, you can’t make calls or use drop-in with third-party devices.
More crucially, many third-party speakers can’t be placed into a smart home group. This is massively restrictive. I’ve covered this in more detail below, but the short version is that when Alexa devices are put into groups with other smart devices, voice control is easier. For example, if you say, “Alexa, turn on the lights”, she knows which lights you’re talking about; outside of a group, you have to explicitly name the device that you want to control.
That’s not to say that third-party Alexa devices are useless, just that they may not have the full range of capabilities that I’ve listed here. Our reviews will explain any issues.
Amazon Alexa – Personal assistant capabilities
At its most basic, Amazon Alexa is a voice assistant designed to help out with basic tasks. For the most part it does this job well, providing actions and options that you’d expect.
For example, you can ask the time, set an alarm, start a timer, find out the current weather conditions and so on. Link Alexa to your Gmail, Microsoft or Apple accounts and you can get your calendar appointments read out to you, or even create new ones. Unlike Google Assistant, Alexa can even work with paid-for G Suite accounts.
Multiple users are supported, too, with Alexa able to recognise individual voices and offer up personalised information from their own accounts.
Best Amazon Echo Deals
A great bundle to kickstart your smart home system, enjoy Alexa across both your Echo and Smart Plug, allowing you to turn on an appliance of your choosing.
Not feeling the bundle? Well, enjoy this fantastic price cut from £89.99, down to £69.99 and have Alexa as your right hand woman for less.
Alexa can also answer some simple questions, from maths to how you spell a word. Alexa used to be relatively dumb beyond this, and couldn’t even offer directions or traffic updates, bar information from your home address to your work address.
However, now you can ask Alexa for directions, and you’ll get them, along with current traffic conditions. But, the results aren’t always perfect; Alexa can struggle. Ask how long it takes to drive to Heathrow and Alexa will tell you how far it is, but without knowing your speed it’s impossible to know how long it will take. Google Assistant gives you the current driving time.
Local business searches have improved, and you can ask for a list of local pizza restaurants. Alexa’s information can be a little out of date and not as good as that of Google Home.
In general, interacting with Alexa can be a bit clunky, and I find myself having to format my questions in a specific way to make myself understood. Alexa also doesn’t understand context – so you can’t, for example, ask for today’s weather and then say, “and the weekend?”.
One frustrating thing about the single-word wake-up phrase is that Alexa wakes up regularly, mishearing ordinary conversation. This will be particularly annoying if you have someone in your house called Alexa, or even Alex. You can change the wake-up word, although “Amazon” or “Computer” are likely to cause as many problems. A two-word wake-up phrase would help ease the issue.
Best Amazon Echo Dot Deals
The Echo Dot was always great value for money but with its new design, the Dot is finally as visually appealing as the Google Home Mini, making it a serious contender as your go-to smart speaker.
When Alexa can’t do something, the chances are that there’s a skill that does. Skills are effectively apps for the voice assistant, adding new features, such as live Tube updates and the like. There’s a huge library of skills to search through in the app. Many are poor, but there’s a big selection of quality add-ons. Most importantly, being able to expand what Alexa can do means that this personal assistant can do far more than Google Assistant.

Now, Alexa can do even more thanks to Amazon Alexa Blueprints. These let you create your own custom skills that you can run in your home or even share with friends. To keep things simple, Amazon has used a series of basic templates that you populate with the information that you want.
Many skills are based around the Q&A format. For example, you can set a Home Guest skill, which helps people staying in your house find the things that they need. Guests can ask Alexa what the Wi-Fi code is or where the spare toilet roll is, having the smart speaker dish out the answers. This is a powerful way to expand what Alexa is capable of.
Amazon Alexa – Drop in, calls and messages
Amazon recently added voice and video calls, and the drop-in intercom feature. Both work either locally inside your home, or externally to friends with Echo devices who are in your contacts book. The difference between a call and drop-in is how the person at the other end responds.
A call has to be answered, making it useful for talking to a friend over the internet; all of their Echo devices will ring (bar those set to Do Not Disturb).
Drop-ins are automatically connected, making the Echo a useful intercom system for the home, or just to see what’s going on at home when you’re out. Drop-in settings are managed by device. By default, drop-in is only enabled for members of your household and contacts with permission, but you can change that to only household members, or disable the feature entirely.
Amazon also has Announcements, where you can transmit a voice message to all Echo devices in your home (“Alexa, announce dinner is ready”). If you want to get the kids’ attention, then it’s a handy tool and matches Google Home’s Broadcast feature.
Call quality, both audio and video, is excellent. I find it particularly useful in-house as a way to talk to other people when I’m too lazy to stand up and move. A recent update lets you make calls or drop in from the Alexa app on your phone or tablet, too.
With the Skype integration, you can hook your Alexa speakers up to your VoIP account and make calls. These can either be over the internet (Skype-to-Skype) or telephone calls using your Skype credit. That’s not quite as powerful as the free landline and mobile calls that Google gives you with the Google Home.
You also can’t set the outbound caller ID to match that of your mobile phone, as you can with Google. The nearest option is to buy a number from Skype and make out-bound calls from this. Alexa can call anyone in your Skype address book, although you can manually say a number to call, too. It’s a shame that you can’t just say the name of local business.

Amazon Alexa – Smart home
There’s no doubting that Alexa is the king of the smart home. Thanks to the easy-to-develop skills and popularity of the Echo devices, Alexa is the first stop for smart home manufacturers. Google Home is slowly starting to catch up, but Amazon maintains a strong lead. And, as new products are launched, most come with Alexa support, while Google Assistant support can be delayed, although this is starting to change.
Amazon’s voice control is simple, although you need to format your phrase carefully. The phrasing changes from device to device. For most smart home devices you can say something along the lines of, “Alexa, turn on living room lights”.
Other devices require you to ask the skill to do something. If you want to turn on your Dyson 360 Eye robot vacuum cleaner, for example, you have to say, “Alexa, ask Dyson to turn on”. Remembering what your devices are called and which phrasing to use can be tricky at times. This isn’t helped by Alexa occasionally mishearing what you’re saying, performing an action on a different device entirely.
Best Amazon Echo Spot Deals
Want to turn off the lights or switch off the TV as you set your smart alarm clock with the Echo Spot? Why not get this great bundle and turn any household appliance smart with the Amazon Smart Plug.
Thanks to more recent updates, Amazon Alexa now lets you sort devices into groups, and also lists devices by type. This makes finding the one you want much easier. And, you can control devices from the app, too, say setting the temperature on your Nest Thermostat or changing the colour of a Philips Hue bulb. It’s still not perfect; you can’t, at the time of writing, change the temperature of a Honeywell Evohome system.
However, you can group multiple devices together for combined control, and you can change the name of a device in the app. As of a recent update, you can now include your Alexa devices in a smart home group. This makes the associated Alexa device ‘aware’ of where it’s placed. For example, if you create a group for your living room and include all of your lights and an Alexa device, you ca talk directly to that Echo and say, “Alexa, turn off lights”. This will turn off all lights, without you having to mention which ones you want to turn off.
Likewise, you can set a temperature on your smart thermostat without having to say which device you want to control. It’s a simple update, but one that makes Alexa far smarter than previously, and easier to control, shortening the commands that you have to use. If you want to control a device outside of that group, you can just name it, such as, “Alexa, turn off dining room light”.
In-app, groups have a toggle on/off switch, so you can turn off compatible devices all in one go. Compatible devices are those that act like a switch, including smart plugs and smart lights.
Smartly, with some devices, Amazon pulls in the default sorting. For example, with Philips Hue bulbs Alexa can see and control the rooms that you’ve already configured. This is something that Google Home can’t do.
Each smart home device can be disabled if you don’t want voice control of it, but you can’t remove devices from the app; this can only be done through the web portal.
More recently, Amazon has enabled Routines, letting you perform a few steps at once when you say a particular phrase. For example, you could set “Alexa, goodbye” to switch off all of your lights when you go out. Routines are currently very limited and let you turn lights on and off, and toggle some modes on some thermostats but not all. With Nest thermostats, you can’t use Routines at all. Honeywell Evohome lets you trigger specific options, such as turning on Away mode.
Largely, the issue comes down to the way that the manufacturer created its Echo Skill. Those manufacturers that let their devices be individually grouped and enable special modes, such as Hue Scenes or Honeywell modes, to be seen in the app are generally the most flexible. The worst skills are those that require you to ask the Skill do to something, such as starting a clean. For these types of Skill, Alexa can’t see the underlying hardware, so can’t use these devices in Routines.

Brief mode is another great, recent addition. Rather than Alexa babbling away telling you what you’ve done, when you’ve just asked to turn a light down, Brief mode gets Alexa to respond to simple commands with a low beep. That makes the system far easier to use, still giving you a littlel bit of audible feedback that the command has been received.
Amazon Alexa – Music
Echo devices can play music from Sonos, TuneIn radio or, of course, Amazon Prime Music. You can even group multiple Echo devices to have music play through them all, although this feature doesn’t support Spotify. And, creating a group has to be done in the app in a fairly clunky way; it certainly isn’t as easy as grouping together your Sonos speakers.
Music quality depends on the device you’re using. Voice control is neat, but it isn’t always easy to say exactly what you want to listen to – I find that trying to specify a particular Spotify playlist often leads to the wrong track being played. It’s far more effective to use the Spotify app to select the track or playlist you want and then use Spotify Connect to send the audio to an Echo. Voice commands work far better for pausing, skipping and changing volume.
Sonos integration is great to see, and you can do all of the same things to your players as you can Echo devices. The only restrictions are that you can’t group or ungroup players, and you can’t adjust the group volume on pre-grouped devices. Neatly, when you trigger Alexa the Sonos volume is dipped, so that your Echo can pick-up your command more easily.
However, it’s frustrating that Alexa dips the volume of all Sonos players. It would be better if you could place devices into rooms; that way, when you triggered one Echo, it would only have to temporarily drop the volume of one device.
Commands are also quite clunky, and as mentioned above, recalling the exact phrasing to use can be a pain. For example, I found that “Alexa, stop playing in the office” didn’t work; but, “Alexa, stop playing music in the office” did.
Again, it’s just as hard to get Sonos to play the right track or playlist, so I prefer to set things off with the main Sonos app, using Alexa for volume, play/pause and volume control.
Amazon has also recently boosted the quality of the audio from its own Echo speakers. While the likes of the Amazon Echo Plus (2nd) gen are better to listen to than their predecessors, Amazon has now added the ability to create a stereo pair, so you can use two of the same Echo speakers together, one for the left channel and one for the right channel. To find out how, the guide on How to create an Amazon Echo stereo pair gives you everything you need to know.
On top of that, the Amazon Echo Sub is a wireless bass speaker that adds to the low frequency prowess of your smart speakers. The guide, how to add an Amazon Echo Sub and configure Alexa EQ settings shows you how to get started. Combining two Echo Plus devices and an Echo Sub in one package gives you a great combination of sound for surprisingly little money.
Amazon Alexa – Films and TV
With the video-enabled Echo devices, you can find film trailers or shows from Amazon Prime Video. On the Echo Show, this can be a neat way of keeping up with programmes you’re watching, although the comparatively low-resolution screen means that you’re probably better watching on a TV.
Search results on the Show can be a bit hit and miss. Ask to find The Tick and you can see the show, but you can’t select an episode using the touchscreen; the next episode you haven’t watched is viewed. If you want to pick an episode, you have to say what you want to watch. Most other searches work, but it’s a shame that you can’t send content from the Prime Video app on your phone to an Echo device; you can only send to a Fire TV device.
On Fire TV devices with the Alexa Remote, you get voice search for Netflix and Amazon Prime playback, as well as apps. Arguably, voice search works better here than on the voice-only devices, as your TV shows the results, which you can then select with the remote control.
You can’t pause or continue playing using your voice, but since you have to hold the remote why would you want to? The remote does give you the option to skip forward or reverse by a set time, which can be handy, such as “fast forward five minutes”.
Neatly, the Alexa Remote responds to all standard Alexa commands and home control, too, including displaying the feed from any video cameras.
You can also link an Echo to one Fire Stick or Fire TV, giving you voice control over playback. Realistically, it’s easier to reach for the remote than asking Alexa to pause playback. You can’t show the feed from a video camera using this method, which is a shame.

Amazon Alexa – Screen-enabled devices
Get a device with a screen – such as the Amazon Echo Show or Echo Spot, but also the Fire TV and tablets – and you get a range of additional features. As well as responding via voice, Alexa can display more information on the screen. For example: ask for the weather, and you get a forecast on-screen for the week ahead.
Touchscreen devices let you interact with what’s on-screen, too. Get a calendar appointment up on-screen on the Echo Show, for example, and you can delete the event.
Some skills have been updated to use the screen, too. If you’ve got a supported video camera, for example, you can view the live feed. It’s a little frustrating that the skills don’t let you do more. For example, it would be useful if you could answer a Ring Video Doorbell from the Echo Show, rather than just seeing the video stream when you ask. Fortunately, this is coming in a future update.
Arguably, Amazon’s touchscreen Echo devices are the best, giving a fuller experience than the smart speakers alone.
Best Echo Show (2nd Gen) Deals
The Echo Show was always a great product but it was hindered by lacklustre design. Not anymore. The all-new second gen Echo Show features a larger screen and a gorgeous fabric cover to make it seamlessly blend in with the decor of your home. This bundle also includes a free Philips Hue White Bulb.

Amazon Alexa – Conclusion
A powerful and extendable smart assistant, Amazon Alexa is currently king of the smart home, and is available on a wider range of devices than the Google Assistant. Importantly, Alexa is getting better all of the time, with Amazon adding new features and abilities.
The downside is that Alexa isn’t always as easy to converse with as Google Assistant (see Amazon Alexa vs Google Home for more information), and doesn’t always give you what you’re asking for. Understanding natural language is the main area that Amazon needs to work on. That said, for the scope, range of products and total smart home coverage, Alexa is a top smart assistant.
