If you're striving towards a more polite household, your Google Home smart speaker will soon have your back. Google announced a feature called Pretty Please at the Google I/O Developer Conference here on Tuesday that will cause your Google Home to respond positively to polite phrasing such as "please" and "thank you." Pretty Please will even prompt your child to say "the magic word" when they give a command.

Google Home is a smart speaker that responds to your voice commands through Google's digital assistant (just called Google Assistant). You can ask it to search the web, check your calendar, play music, control your smart home and more. Recently, Google has made a push to make Google Assistant more family friendly with games and activities created by partners such as Disney.
