Google’s voice-activated assistant can now recognize who’s talking to it on the Google’s Home speaker. An update coming out Thursday, April 20, 2017, will enable Home’s built-in assistant to learn the different voices of up to six people, although they can’t all be talking to the internet-connected speaker at the same time. The feature will allow Home to be more personal in some responses and give it a potential advantage over Amazon.com’s Echo. (AP Photo/Eric Risberg, File)
