Google announced that they have integrated Multilingual support for all devices with Google Assistant, due to their advancement in Speech Recognition. Through this, users will be able to interchangeably speak two separate languages and Google Assistant will be able to handle this level of interaction. This feature is currently open to 6 languages (English, German, French, Spanish, Italian, and Japanese) with more coming.
Not to mention, Google also introduced 6 new Routines for Google Assistant. This allows for a wider array of actions that your device can take with a single command. You can read more in their blogpost.
