What is Google Home, how does it work, and when can you buy it?

Google Home

• Voice-activated speaker, similar to Amazon Echo
• Uses Google Assistant AI
• Google is looking to embed itself in your home, in a bid to one-up Amazon.
• Amazon announced its Echo speaker, complete with its voice-controlled personal assistant called Alexa, back in 2014. Google followed with Home in 2016 - its hands-free smart speaker with Google Assistant built-in - for the USA, and now it's the UK's turn to experience the smart home system.
  

• What is Google Home?

• Google Home is a Wi-Fi speaker that also works as a smarthome control centre and an assistant for the whole family. You can use it to playback entertainment throughout your entire home, effortlessly manage everyday tasks, and ask Google things you want to know.
• The device itself has interchangeable bases available in various colours and finishes (such as metal and fabric, allowing you to match it to your decor). Underneath that swappable shell there is a speaker that can playback songs and allow Google Assistant to talk to you.
• At the top of the device there is a capacitive touch display with four LEDs. You'll use this interact with Home, trigger Assistant, adjust volume, and so forth. As for buttons, there are none at the top (just dual mics that listen for your voice). There is a single mute button on the shell. Google Home is able to filter and separate speech from noise and offers "best-in-class voice recognition", according to Google.
• The speaker features dual side-facing passive radiators, which deliver full range, clear highs, and rich bass. And the entire thing is available in three colour variations: Mango, Marine, and Violet bases join Carbon, Snow, and Copper tops. The bases can be swapped out.

  How does Google Home work?

• Music and video playback

• Because Google Home is a Wi-Fi speaker, it can stream music directly from the cloud. With it you can access songs, playlists, albums, artists, and podcasts from your favourite music services just by asking with your voice. Or, if you prefer, you can send music from your Android or iOS device through Google Cast.
• That last bit is important because, with Google Cast support, you'll be able to use Google Home to control other connected speakers in your home. You'll even get multi-room playback, meaning you can add one or more Google Home devices to a group of speakers in order to blast tunes throughout your house. But that's not all: Google Home will let you control your video content.
• Let's say you want to watch your latest episode of Daredevil on Netflix, or some sort of cat video on YouTube. Just issue a voice command to Google Home, and the content will appear on your TV (again, thanks to Google Cast support).

  Smart home hub

• Google Home can be a control centre for your entire home, because it has access to Google Assistant (see below). It will let you do the basics like set alarms and timers and manage to-do lists and shopping lists. It will also connect your smarthome and support popular network systems. That means you will be able to control smart lights, switches, doors, and Google's own Nest products.
• Google plans to work with developers so you can control things beyond the home too, such as booking a car, ordering dinner, or sending flowers to a loved one. And the best part is you will be able to do this with just your voice.
• 
  

  Ask Google

• Speaking of your voice, Google Home will let you ask Google anything. You can ask for the weather or check facts on Wikipedia. You will have access to Google's 17 years of search experience. That allows you to ask specific questions such as "How much fat is in an avocado?" or "What is Wayne Rooney's shirt number?" Those types of questions would stump Amazon Echo, but not Google.
• Because Google Home has Google Assistant, you can be conversational and ask follow-up questions like "Where did he go to school?" and Google Home will be able to connect the "he" pronoun to your previous question about Rooney or whoever in order to serve up an accurate answer. You can even ask complex stuff like "What was the US population when NASA was established?"
• Google Home will give you immediate answers each time. Also, it can read the relevant parts of webpages back to you.

  Which services does Google Home support?

• At launch, Google Home works with YouTube Music, Spotify, Pandora, Google Play Music, TuneIn, and iHeart Radio.
• In the UK there are specific services, such as BBC, Telegraph and Guardian news sources.
  With support for these services, you can ask, "OK Google, play that Shakira song from Zootopia." Without having to name the song, Home can figure it out and play it from your favourite app. Thanks to Google Assistant and its machine-learning capabilities, Google Home knows you and your preferences.
  Google Home also works with Nest, SmartThings, Philips Hue, and IFTTT, which means you'll be able to control these smart home devices and activate your IFTTT recipes using the speaker. Google Home also acts as a Chromecast Audio receiver.

• What is Google Assistant in Google Home?

• Back at Google I/O 2016 Google announced a new Siri-like bot that is an adaption of Google Now and Ok Google. It's called Google Assistant, and it improves the two-way conversation experience of those services thanks to AI and machine learning.
• These advances essentially add context to your questions. For instance, when you say "OK Google" followed by "What's playing tonight?", Google Assistant will show films at your local cinema. But if you add "We're planning on bringing the kids", Google Assistant will know to serve up showtimes for kid-friendly films. You could then say "Let's see the Jungle Book", and Assistant will buy tickets.
• You can even ask "Is the Jungle Book any good?", and then the assistant will display reviews, ratings, and a trailer. Google Assistant is able to string your questions together in order to determine context and serve up the right information. It can do basic stuff like retrieve your travel itinerary, daily schedule, commute time to work, package delivery information, and more.
• Google Home isn't the only device with access to the Google Assistant however. You'll also be able to use the assistant with Android Nougat devices and your Android Auto head unit. Here's how Google explained its new assistant:
