Google Assistant is the search giant’s voice-activated virtual assistant that features in the Google Home and many Android phones alike. Designed to answer questions, manage and plan your day, control your smart home, plus plenty more, this is one of the most prominent personal assistants in the world.
Like its main competition, Amazon Alexa, Google Assistant runs entirely in the cloud. That means that any device with which it integrates will have pretty much the same functionality. For that reason, this guide contains all of the latest Google Assistant features and updates. Hardware is reviewed separately.
Before we get into the details of the system, it’s important to point out that most of the features we talk about here work on all devices, both those made by Google and third-party ones. That’s quite different to Amazon Alexa third-party devices, which miss out on some of the core features, including Echo-to-Echo call. In other words, you can buy a Google Assistant smart device from anyone and enjoy the same features. That makes these devices and this ecosystem a little more flexible than Amazon’s.

Google Assistant – Which devices use the smart assistant?
Google is expanding its range of products that have Google Assistant built in. Now, the personal assistant is available on Google’s own smart speakers, plus third-party speakers from the likes of Panasonic, Android smartphones and tablets, and even smart cameras. Cleverly, Google doesn’t restrict features on third-party devices, so you get the same experience whether you buy from Google or now.
Google Assistant – Personal assistant capabilities
If the Google Assistant has one advantage, it’s that it’s powered by Google’s services, from search to maps and beyond. Out of the box, then, it’s fair to say that Google Assistant is that bit smarter than its rivals.
Ask for the nearest pizza restaurant, for example, and you’ll get an up-to-date list. Ask for driving directions to Heathrow Airport, and you’ll get the latest driving instructions from your home location (unless you ask otherwise), complete with an estimated time of arrival. Google can send the directions to your phone, too, provided both devices are signed in with the same Google Account.
To do this, you need to set up Voice Match via the Google Home app. Select Devices and you should see a blue banner that says ‘Link your account with Voice Match’. Then, provided your phone and Google Home device are linked, you can say something like, “OK Google, directions to Heathrow”, followed by, “Send to my phone”.
You’ll then receive a pop-up notification on your handset. Multiple users can configure Voice Match, returning personalised information such as calendar entries, just as with Alexa.
Results can be pulled from search consistently, too, whether you want to know who stars in the Avengers movies, how far away the moon is, or just when the next bank holiday is – the Google Assistant routinely delivers the best results.
And, unlike Alexa, the Google Assistant more often understands exactly what I ask of it. The former often suffers the odd blip of either not understanding what I’ve asked or returning irrelevant information. The gap between the two has certainly closed, but the Google Assistant is generally better.
Of course, the Google Assistant offers up all the things you’d expect of a personal assistant. That includes setting timers and alarms, providing up-to-date weather forecasts, and pulling information from your calendar. The last one is true for anyone bar G Suite account holders; if you pay for your Gmail and other services, the Google Assistant can’t read any of the information at all. That’s plain odd, as Amazon Alexa has been able to do this since day one, and there appears to be no good reason why Google still can’t do the same.
Conversationally, the Google Assistant is easier to talk to. I find that natural language is interpreted better and more accurately than with rival systems. Plus, Google understands context, enabling you to continue a conversation. Ask, “What’s the weather like today?” followed by, “And at the weekend?”, and you get weather reports for today and tomorrow, without having to repeat the entire conversation.
Admittedly, the number of times that this becomes useful is limited, but it’s just an example of how the Google Assistant is that little bit more natural to converse with.
Google is expandable with Actions, which are developed and automatically integrated into the system without needing to be installed. That’s good news, but there isn’t a central store of available Actions to view capabilities – and Alexa, so far, is expandable and does more.
I slightly prefer the two-word wake-up phrase for Google (“Hey Google” or “OK Google”), since it means that Google Assistant rarely wakes up by mistake; this is a constant problem for Alexa. That said, both of Google’s wake-up phrases are a bit of a mouthful.

Google Assistant – Voice calls and messages
The Google Assistant is the first to let you make free calls to local landlines and mobile phones via Google Home devices. Calls can be placed to local businesses (“Hey Google, call Papa Johns”) or anyone in your personal address book. Even better, you can set the outgoing number as your own mobile phone number, so it looks as though you’re calling from your own phone.
Google Home calling works brilliantly with both the main Google Home and Google Home Mini, with call quality matching the best mobile calls. It’s hugely convenient, too, as you can quickly make a call without having to reach for your handset.
Via Google Duo, you can now call between your Google Home speakers, although it needs some configuration to get working; Ech speakers can do this out-of-the-box. You can also use Broadcast, which lets you send a voice message to all Google Home devices that you own. This is a good way to get attention – shouting out to the kids to come down for dinner, for example – but full-on voice calls would be nice.
With the launch of smart displays, Google has now included Google Duo calls. You can either make video or audio calls over the internet to any compatible devices. Duo isn’t as well supported as, say, FaceTime, but it’s handy to have this type of option available and means that you can make calls to other Smart Display users for free. Duo is a bit of a pain to set up, but the guide on how to set up Google Duo on smart displays for video and audio calls.
Google Assistant – Smart home
The Google Assistant used to lag behind Amazon Alexa when it comes to smart home support. Now, Google has massively caught up and supports nearly the same range of products as Amazon does. There are only some minor differences. For example, Dyson Link products, aren’t currently supported by the Google Assistant.
There are also some strange differences between Alexa Skills and Google Actions. For example, Alexa could switch the Nest Thermostat to Eco mode, but the Google Assistant couldn’t, until recently. However, it can turn the Thermostat back to heat mode.
In-app, the Google Assistant organises your smart devices into rooms, which makes finding them easier. You can then control devices in groups, such as turning off all devices in your living room. It doesn’t always work perfectly, though. I had two groups, one called ‘Office’ and one called ‘Mad’s Office’ (for my wife). Saying, “OK Google, turn off office” prompted the assistant to turn off lights in both rooms. Renaming ‘Office’ to ‘Dave Office’ fixed this, temporarily. Then, I added a Google Nest Hub into the mix, and now saying, “OK Google, turn off Dave office”, prompts the Home Hub to append the word ‘display’ to the end of the sentence. Google then complains that it can’t turn off the ‘Dave office display’. Sometimes, Google just needs to do exactly what it’s told.
As of a recent update, Google Home devices now understand which room they’re in. So, you can now say, “OK Google, turn off light”, and it understands which room you’re in. That makes control a lot easier and means that you don’t have to remember the names for the devices that you want to control. To be less annoying, Google simply plays a chime, rather than giving you a voice reply when controlling devices in the same room; however, this doesn’t work if you’re using a Sonos speaker, such as the Sonos One. Here, the speaker will tell you exactly what it’s doing (“turning off four lights”, for example) when you control devices in the same room.
Strangely, Google doesn’t pull in as many smart device features as Alexa. For example, while Alexa can control Hue lights by the rooms that you’ve defined in the Philips app, Google Home can’t do the same thing and makes you organise everything manually. If you change where your lights are located, it means you have to change the settings in two places.
Google now provides in-app control for smart devices. Letting turn on and control lights, thermostats and other smart devices. For example, you can control the brightness of a set of lights in a room, or turn a thermostat up.
It’s good to see routines are finally available in the UK, too. This lets you control multiple devices using a single command and means that Google now rivals Amazon for features. Truly, Google has caught up with Amazon in all areas bar one: there are still a few products that don’t work with the Google Assistant, although this list is diminishing.

Google Routines are more powerful than Alexa ones in some ways. With the Google Assistant you can make a routine run any command: you just type in what you’re normally speak. However, Google Assistant Routines miss out on one key Alexa feature: you can’t trigger them based on a smart device, say turning off lights when a motion sensor no longer detects motion. This makes Alexa the far more powerful smart home assistant.
Google has also gone through a process of trying to merge its Nest products into the Google Home app, but it’s not entirely successful and the Home app can be a bit of a mess. Then, there’s the fact that a few devices still insist on being installed through the Google Assistant app rather than the Home app. Alexa keeps everything in one place and Google has a big tidy up job.
Google Assistant – Music
Google supports Google Play Music, Deezer and Spotify for streaming. For each service, you can ask to play a specific track, album or playlist. However, the usual issues arise, and it’s often easier to find the content you want using the particular music app you want, and then use Cast to send it to a Google Home or Chromecast device. Controlling playback with your voice using the Assistant is then quite straightforward.
You can group multiple devices to create a playback group. It’s a little clunky to do this and nowhere near as easy as doing the same job with Sonos.
You can control any devices that support Google Cast, too, such as many smart multiroom speakers or a Chromecast Audio. That’s quite neat and is certainly useful for pausing playback or adjusting volume. Talking to Google Home dips the volume on any speakers that you’re casting to, so your music doesn’t drown out your voice commands.
There’s no a Sonos integration and you can select a Sonos speaker as the default for music. My guide on how to use Sonos with Google Assistant tells you more. You get the same features as on Alexa, although Google will not dip the volume on the Sonos speaker. And, once you’ve set the default Sonos speaker asking Google to change volume changes volume on the Sonos speaker not the smart speaker that you’re talking to, which is plain annoying.
Google Assistant – Films and TV
The Google Assistant can connect to any Chromecast or Chromecast Ultra devices you have around the home, streaming content from popular services, such as Netflix. Again, voice searching for content isn’t always accurate; it’s often best to start the playback from your phone.
However, having voice control of playback is often easier: if your phone rings, pausing what you’re watching with your voice is far easier than answering your phone and then trying to pause.
Control is also easier. With Alexa, you have to pair an Echo device to a Fire TV in the app. With the Google Assistant, you can say which device you want to control (“OK Google, pause the living room TV”).
If you have a smart display, you can now send Netflix and Disney Plus content to watch, too.
Google Assistant – Screen-enabled devices
Using the Google Assistant on a device with a screen brings in some more options, but the experience depends on the device. For example, with a phone you can ask for the weather and your display will show you a pictorial forecast for the coming week.
But, you can’t view video feeds from supported smart cameras on your phone. Instead, you can only stream video footage from smart cameras – such as the Nest Cam IQ Outdoor – to Chromecasts and Smart Displays. It’s still a potentially neat feature, letting you quickly get a security update. And, with the Google Home Hub, you can now get a preview of who’s at the door when someone presses your Nest Hello and answer from the screen; normal voice speakers broadcast that someone’s there but don’t let you anser.e
Smart Displays dramatically change what the Google Assistant can do. Ask to control a smart device, and the Smart Display pops up an on-screen control to let you fine-tune the experience. For example, you can turn on your lights with your voice and then set the brightness or colour with touch. The Home View feature, as this is called, can also be accessed from the top of the screen with a swipe down motion, giving you touch control over lights and thermostats.
Ask a Smart Display for a recipe, and you get a long list of options; football results are presented with a current league table; YouTube videos start playing on screen; and directions are shown directly on the display; plus there’s lots more. In terms of information accuracy and display information, devices such as the Home Hub are way ahead of the Amazon Echo Show.
Google Assistant – Conclusion
By far the more natural voice assistant to talk to, the Google Assistant generally picks up what you’re saying with a higher degree of accuracy than Amazon Alexa. There are some neat integrations in there, too, such as the ability to send results to your phone.
Voice calls to landlines is an excellent feature, and I often end up making calls on my Google Home Mini rather than reaching for my phone. Thanks to recent updates, Google Assistant now supports the same range of features and, mostly, devices as Amazon Alexa. Add in the growing number of devices and the smarter personal assistant, and the Google Assistant is suddenly looking like a real winner.
