Amazon patents new Alexa feature that knows when you're ill and offers you medicine

Amazon has patented a new version of its virtual assistant Alexa which can automatically detect when you're ill and offer to sell you medicine. The proposed feature would analyse speech and identify other signs of illness or emotion. One example given in the patent is a woman coughing and sniffling while she speaks to her Amazon Echo device. Alexa first suggests some chicken soup to cure her cold, and then offers to order cough drops on Amazon. If Amazon were to introduce this technology, it could compete with a service planned by the NHS.
