Introduction to the Google Assistant Service

The Google Assistant Service gives you full control over the integration with the Assistant by providing a streaming endpoint. Stream a user audio query to this endpoint to receive a Google Assistant audio response.

You can generate bindings for this API from a variety of languages (for example, Go, Node.js, C++, and Java) on all platforms supported by gRPC.

Basic hardware requirements

Before you begin, you'll need the following components:

  • A device running on one of the supported platforms, with internet connectivity
  • A microphone
  • A speaker


The following sections are applicable to Python and the Raspberry Pi.

If you do not want to use Python, use the integration guide to integrate the Google Assistant Service in other languages and on different platforms.
