Custom Devices with Google Assistant

You can't launch commercial devices that integrate with the Google Assistant SDK. It's available for experimental and non-commercial uses only.

The Google Assistant SDK lets you add voice control, natural language understanding and Google’s smarts to your ideas.

Your project captures an utterance (a spoken audio request, such as What's on my calendar?), sends it to the Google Assistant, and receives a spoken audio response in addition to the raw text of the utterance.
