Shopping by voice on Amazon Echo could be a ripoff

In the name of convenience, Amazon and Walmart are pushing people to shop by just talking to a digital assistant. Shopping by voice means giving orders to the Alexa assistant on Amazon's Echo speaker and other devices, even if your hands are tied up with dinner or dirty diapers. And next month, Walmart will start offering voice shopping, too, with the Google Assistant on the rival Home speaker. FILE - This file photo provided by Amazon shows models of the Amazon Echo Show. With Echo Show, Amazon has given its voice-enabled Echo speaker a touch screen and video-calling capabilities as it competes with Google's efforts at bringing'smarts' to the home. Amazon has been ramping up efforts to get more people to shop using the Alexa voice assistant on Echo speakers and other Amazon devices.
