The Amazon Echo is a voice-activated home audio speaker system with Bluetooth and Wi-Fi connectivity. Here we answer your Amazon Echo questions and explain what are the various products in our complete guide to Amazon Echo.

Who is Alexa? 

Alexa is the wake word for Amazon Echo. Its digital voice assistant will happily fulfil any of your spoken commands, from setting an alarm to searching the web to answer your burning questions and playing music. Echo is constantly learning, too, adapting to your speech patterns, vocabulary and personal preferences. Amazon says that the company is constantly updating the way Alexa listens and responds and will eventually provide an interface with natural-sounding responses. 

What is Amazon Echo? 

Amazon Echo is a cylindrical home audio speaker that integrates a personal voice assistant named Alexa, very much like Siri, Cortana and Google Now on your phone or tablet. It's always on and always connected with Wi-Fi allowing it to sit on your home network and access cloud services, and Bluetooth letting you stream music from mobile devices. 

Alexa can handle things like multiple timers and alarms, IFTTT support, integration with Google Calendar, and lets you listen to Audible audiobooks and re-order Prime-eligible items from Amazon. It can even order your favourite takeaway from Just Eat.

Some of those capabilities are built in, while other 'Skills' have to be enabled in the Alexa app. They're like apps which created by developers and some let you control smart home products, including Philips Hue, LIFX, WEMO and Nest devices.

Amazon Echo 2

On 27 September 2017 Amazon announced its second-generation Echo, which replaces the older version at the new significantly cheaper price of £89.99. Right now it's even cheaper, at £69.99 as part of Amazon's Black Friday sales.

The new Echo has a new shorter and more customisable design, improved sound with Dolby processing, and second-gen far-field technology. Read more about the Echo 2 here.

What is the Echo Show?

It's an Echo with a screen and a camera as well as a 'room-filling speaker'. It's now been announced for the UK and is available to pre-order at £199.99, going on sale on 16 November.

What is the Echo Plus?

The Echo Plus is a bigger and better version of both the original and the new 2nd-gen model. Its increased size allows it to incorporate enhanced speakers - 360-degree sounds comes via a 2.5in woofer and 0.8in tweeter. There's also Dolby processing, which should make your music sound better.

On the top of the Echo Plus are similar controls and seven far-field microphones. Combined with beam-forming technology and noise cancellation, Amazon says the Plus can hear you from any direction-even while music is playing.

The Echo Plus is available to order now at £139.99.

What is the Echo Dot?

Amazon's newly updated Echo Dot brings Alexa support to any room in your home, offering pretty impressive functionality for such a small device. It costs £49.99 and is available from Amazon now, though for Black Friday is down to just £34.99.

First, and most obviously, the Echo Dot will use the Alexa Voice Service to provide users with everything from music playback to the latest news, and even control of smart home devices (if compatible, anyway!). It's also smart enough to work out which Echo you're closer to (if you have more than one) and respond only from that speaker, despite being heard on multiple speakers. 

However, the Echo Dot also features Bluetooth functionality allowing you to connect it to any Bluetooth speaker in your home, bringing Alexa functionality to, say, the high-end Kef Muo Bluetooth speaker. It also allows you to play music from services like Spotify, Prime Music and Pandora without the need for a computer or smartphone. The virtual assistant is activated by simply saying "Alexa" and thanks to its "far-field voice recognition" it can pick up commands from across the room while music is playing from the speaker.

It also features a built-in speaker, allowing the Echo Dot to be used in a number of situations from simulating an alarm clock in your bedroom to reading out a recipe in the kitchen, and can be hooked up to an existing speaker system via a line out cable.

What is the Echo Spot?

For now the Echo Spot is a US-only product, but it will be coming to the UK in 2018. It's a smart alarm clock, and a cross between the Echo Show and Echo Dot.

It's more expensive than the Dot at $129.99 (UK price will be confirmed before it arrives here), but it has greater functionality. There's a 2.5in display that can show the time or allow you to make hands-free calls and video calls. Audio quality won't be amazing, but you can hook up an external speaker via Bluetooth or AUX.

What is the Echo Look?

The Echo Look is another currently US-only product, which costs $199.99 but can be purchased from Amazon.com only by invitation.

Echo Look

A hands-free camera and style assistant, the Echo Look can ensure you are always looking at your best.

Echo Look can take full-length selfies and video at request, allowing you to show off your wardrobe to your heart's content, or for personal use quickly and easily scroll through your outfits and pick out one to wear. The depth-sensing camera has built in LED lighting and computer vision-based background blur.

A dedicated companion app lets you see yourself from every angle, while Style Check can use a combination of machine learning and advice from fashionistas to let you know which outfit looks best.

What is Amazon Tap?

Amazon Tap is a portable Bluetooth and Wi-Fi enabled speaker, providing users with Alexa functionality while on-the-go, and everything that comes with it including music streaming support, smart home support and even the ability to order a pizza from Dominos (in the US, anyway!). However while the Tap provides Alexa functionality, the real focus is on the audio quality - it features dual stereo speakers with Dolby processing, allowing for high-quality vocals and deep bass. It was also designed to provide users with 360 degree sound projection, providing users with omni-directional audio. 

It's small and lightweight making it the ideal travel companion, and the 9-hour battery life should serve most users well. 

Can Amazon Echo hear me while music is playing? 

Yes. Amazon Echo has seven mics hidden inside and around the edges of the speaker, which use beam-forming tech and enhanced noise cancellation, so it'll hear you no matter how loud it is and where you're sitting. 

That's the theory, anyway. In practice, Alexa can't always hear you when the music is loud and you might have to turn it down a bit manually before she'll respond.

What is Amazon Echo's audio quality like? 

The quality is fairly decent from the original Echo, although we have not yet tried the newer versions which should offer improved audio. It's excellent for things like news briefings, audio books and anything else spoken. It's not the greatest for music, but it's perfectly acceptable. 

Inside the Echo is a 2.5in woofer that delivers deep bass, and a 2in tweeter for hitting the high notes. Amazon also says a reflex port is able to enhance the woofer's output without distortion. 

The Echo Dot has a much smaller speaker that's not great for music at all, but pretty good for vocals. The idea with the Dot is that you connect it to your existing hi-fi or a Bluetooth speaker. 

How do I control Amazon Echo? 

Besides using the Alexa wake command, an Amazon Echo companion app is available for Fire OS and Android, and can be accessed via the browser on iOS devices, PCs and laptops. This lets you manage alarms, music, shopping lists and more. 

There is also a volume ring at the top of the big Echo, (buttons on the Echo Dot), plus Action and mic mute buttons on top.
