Wrapper around Google's pushtotalk.py for assistant interaction without the google-assistant-library

After Google's sudden deprecation of the assistant library users have been left with nearly no choice for interacting with the assistant. The gRPC interface is embarassingly undocumented and making it work means hammering the extremely hackish and poorly designed pushtotalk.py example.

I have made a lot of dirty work myself and created this repository to provide users with an easy way to get their assistant to work even without the assistant library. To get it to work:

• Install the Google Assistant SDK and oauthlib:

pip install 'google-assistant-sdk[samples]' 'google-auth-oauthlib[tool]'

• Generate a credentials file:

google-oauthlib-tool --scope https://www.googleapis.com/auth/assistant-sdk-prototype \
          --save --headless --client-secrets /path/to/client_secret_client-id.json

• Clone this repository and run assistant_sample.py to test the assistant:

import sys

from assistant import Assistant

assistant = Assistant()

while True:
    print('Press ENTER to start a conversation, Ctrl+C to terminate')

    try:
        sys.stdin.readline()
    except KeyboardInterrupt:
        print('\nExiting the assistant')
        break

    interactions = assistant.start_conversation()
    print(interactions)
    assistant.stop_conversation()

• The gRPC implementation doesn't support hotword detection (no more "OK Google" support). You can however use Snowboy as a workaround. Download or train your voice model on the Snowboy website, get the model file and install the Python bindings:

pip install snowboy

• Run the code in hotword_sample.py for hotword+assistant support:

from assistant import Assistant
from assistant.hotword import HotwordService

assistant = Assistant()
service = HotwordService(model='/path/to/your/model/file', assistant=assistant)
service.start()
service.join()
