Actions on Google lets you extend the functionality of the Google Assistant with Actions.

Actions let users get things done through a conversational interface that can range from a quick command to turn on some lights or a longer conversation, such as playing a trivia game.

If you live in a multilingual home, Google has also made it so Google Home speakers can understand two languages at once. You can currently choose a combination of any two of the currently supported languages: English, German, French, Spanish, Italian and Japanese. 

Conversations, as an example, may include: (refer CNET for example,  see the page helloEd Helpful Links)

Routines

 Google Home now has routines that can be triggered with a custom phrase or on a custom schedule. In short, you can create a routine that turns off the lights around the house, locks the front door, adjusts the temperature and plays soothing music when you say, "OK, Google, good night." 

Or you can have a routine that runs every morning on a schedule as an alarm that plays the news, turns on the lights, makes your coffee and creates a timer so you know when it's time to leave the house.
