Python samples for the Google Assistant library

This repository contains a reference sample for the google-assistant-library Python package.

It demonstrates: - Initialization of the Assistant - Basic event handling including hotword detection.



  • Install Python 3

    • Ubuntu/Debian GNU/Linux:

      sudo apt-get update
      sudo apt-get install python3 python3-venv
  • Create a new virtual environment (recommended):

    python3 -m venv env
    env/bin/python -m pip install --upgrade pip setuptools wheel
    source env/bin/activate


Run the sample

  • Install the sample dependencies using pip:

    pip install --upgrade -r requirements.txt
  • Run the hotword sample. The sample waits for the "Ok Google" hotword, then records a voice query and plays back the Google Assistant's answer:

    python -m hotword --device_model_id 'my-model-identifier'


  • If audio is not working, verify the ALSA setup:

    # Play a test sound
    speaker-test -t wav
    # Record and play back some audio using ALSA command-line tools
    arecord --format=S16_LE --duration=5 --rate=16000 --file-type=raw out.raw
    aplay --format=S16_LE --rate=16000 --file-type=raw out.raw
