Google is making it easier for device manufacturers to integrate with Google Assistant technology, including those times when devices need to respond to voice commands without the benefit – or the expense – of being connected to Google’s cloud. To do so, Google is today launching a new set of tools called Google Assistant Connect into preview, before making them broadly available to device makers later this year.

The tools can be used to build devices that leverage an existing connected speaker with Google Assistant to deliver content and respond commands that require cloud computing resources.
