Amazon adds voice recognition to Alexa

Amazon has added a new voice recognition feature to its Alexa smart assistant. It allows the smart speaker and apps to recognise users from their voice, and personalise information to them. It comes just days after Google, which already has a similar feature in its Assistant, launched a raft of devices in its bid to topple Amazon in the personal AI war. Amazon's new Echo (£89.99 / $99) has six'shells' users can swap to customise its appearance. The next generation speaker, which is powered by Amazon's Alexa voice assistant, will have a dedicated woofer and a tweeter for the first time, as well as Dolby sound.
