It offers hands-free voice control for Amazon Music, Prime Music, Spotify and other streaming services.
Even when you're playing music, Echo can use one of its seven hidden mics and so-called 'beam forming technology' to always be able to hear your next request, in spite of how loudly you like your music.
For customers who have multiple Echo devices within hearing distance, Amazon’s ESP technology intelligently calculates the clarity of the customer’s voice and determines which Echo is closest and should respond to the request—instantly.
This feature is now available to customers using both Echo and Echo Dot, with a software update pushed to Echo devices already in use.
In the US, Amazon partnered with brands such as Domino's and Uber to allow you to order a pizza and request a taxi using through Alexa.
Every Echo sold comes with a one-year limited warranty and service included and included in the box is a power adapter, and quick start guide WIRED had a brief, albeit crowded, hands-on with the Echo running Alexa at the UK launch event.
Admittedly we were asking the device questions from a list of approved queries on the demo station surrounded by other journalists all chatting away – but this, in fact showed Alexa’s beam forming and echo cancelling capabilities using that seven-microphone array really works when attempting to lock in on someone calling on the digital assistant in a party environment.
Amazon told WIRED that more list services are coming soon.
The device measures 9.3 x 3.3 x 3.3 inches (235mm x 84mm x 84mm) and weighs 37.5 oz, or 1,064 grams.
Alexa will fulfil your spoken commands, such as setting an alarm or finding the answer to a question you may have.
The Echo is always learning, to adapt to your speech patterns, vocabulary, and personal preferences.
Amazon Prime customers can get it for a limited time at a discount of £50, dropping it to £99.99.
