Google Assistant SDK for Python

This package contains a collection of samples and tools to help you get started with the Google Assistant SDK using Python.

Installing

• You can install using pip:

  pip install --upgrade google-assistant-sdk
  

Usage

google-oauthlib-tool

This tool creates test credentials to authorize devices to call the Google Assistant API when prototyping.

• Follow the steps to configure a Google API Console Project and a Google account to use with the Google Assistant SDK.

• Download the client_secret_XXXXX.json file from the Google API Console Project credentials section and generate credentials:

  pip install --upgrade google-auth-oauthlib[tool]
  google-oauthlib-tool --client-secrets path/to/client_secret_XXXXX.json --scope https://www.googleapis.com/auth/assistant-sdk-prototype --save --headless
  

googlesamples-assistant-audiotest

This tool verifies device setup for audio recording and playback.

• Install the sample's dependencies:

  sudo apt-get install portaudio19-dev libffi-dev libssl-dev
  pip install --upgrade google-assistant-sdk[samples]
  

• Record 10 seconds of audio samples and play them back:

  googlesamples-assistant-audiotest --record-time 10
  

• Adjust the sound device block size and flush size for a soundcard with limited throughput:

  googlesamples-assistant-audiotest --record-time 10 --audio-block-size=3200 --audio-flush-size=6400
  

The same --audio-block-size and --audio-flush-size options can be used on the gRPC samples included in the SDK.

googlesamples-assistant-pushtotalk

This reference sample implements a simple but functional client for the Google Assistant gRPC API.

• Install the sample's dependencies:

  sudo apt-get install portaudio19-dev libffi-dev libssl-dev
  pip install --upgrade google-assistant-sdk[samples]
  

• Try the push to talk sample:

googlesamples-assistant-hotword

This reference sample implements a simple but functional client for the Google Assistant library (linux_arm7l and linux_x86_64).

• Install the google-assistant-library package:

  pip install --upgrade google-assistant-library
  pip install --upgrade google-assistant-sdk[samples]
