What's the magic word?
Amazon's smart assistant Alexa can now be made to encourage children to say: "Please," and: "Thank you," when they ask it something. The new function addresses some parents' concerns that use of the technology was teaching their offspring to sound officious or even rude.
The move has been welcomed by one of Alexa's critics. In January, the research company ChildWise published a report warning that youngsters that grew up accustomed to giving orders to Alexa might become aggressive when they have to interact with humans.
