What command/wake word do I use?
- Amazon Alexa – “Alexa”
- Siri – “Hey Siri”
- Google Assistant – “Hey Google”
You can also personalise this in Settings with most speakers, choosing to use a command which is easier to remember or shorter.
Which smart speaker is best for privacy?
Some people are cautious of smart speakers being able to listen in to everything we do. Most will have some form of a button which allows you to turn off the microphone, but look out for it as a redeeming feature if you’re really concerned.
In what may be a surprise for some people, Amazon’s speakers are actually great privacy-wise, as you can turn the microphone off. Turn the video off on their video speakers, too. You can listen back to your voice recordings at any point and delete them as well, which is good if something has accidentally triggered Alexa to listen in.
You can turn off Siri on the HomePod simply by asking her, and Apple products also come with encryption, anonymous IDs, and other privacy features. It uses random identifiers when you make a command, and they are not associated with your Apple ID, email address, or any other data you stored on your Apple devices.
Sonos speakers also feature encryption, and they do not store the voice recordings you have made. Instead, they are sent to the voice partner you have used for the commands, where you can deal with them appropriately.
Google Assistant products delete recordings once they have fulfilled your request, and anything which has been stored can be deleted at any time. You also have control over what it stores or listens to.
Most have updated their privacy policies to say that only anything recorded after the wake word has been said will be stored, limiting what it can do with what you say at other times.
Do I need a Smart Home hub speaker?
Smart home hubs, which connect either locally or to a cloud, are useful for Internet of Things (IoT) devices that use the Zigbee or Z-Wave protocols or Bluetooth, rather than Wi-Fi.
This includes some brands of doorbells, lights, locks, security cameras, and thermostats. In some cases, a singular phone or smart speaker will allow you to give voice commands to one or two items, but if you have multiple devices to both talk to and be controlled, you may need a centralised hub to make communication easier.
But which to buy can be complicated. You need to think about the smart devices you have in your home, the protocols they use and the platform your smart speakers are on. Also, IFTTT (If This Then That) applets are mostly used now, especially with brands such as Nest home security and Samsung smart lighting, allowing you to set up one thing to happen if something is triggered.
There’s a good chance dedicated hubs will fade out in the next few years, such as their integration in smart speakers now. So, if you will have a huge system of smart devices, stick to a smart speaker with a hub for a futureproof pick. But if you just want to get some smart lights and not bother with anything else, a hub is likely unnecessary.
