This repository contains a way to use a custom hotword with google assistant.

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

Prerequisites

• Python >= 3.4
• Raspberry Pi 3 running Rasbian (or any other linux-arm7l SBC)
• A Google API Console Project
• A Google account

Setup

• Install Python 3

  • Ubuntu/Debian GNU/Linux:

    sudo apt-get update
    sudo apt-get install python3 python3-venv

  • MacOSX, Windows, Other

• Create a new virtual environment (recommended):

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

Authorization

• Follow the steps to configure the project and the Google account.

• Download the client_secret_XXXXX.json file from the Google API Console Project credentials section and generate credentials using google-oauth-tool:

  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

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

• If that works, execute:

    python3 -m jarvis

Changing the hotword

• The hotword can be changed in jarvis.py

Troubleshooting

• 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=16k --file-type=raw out.raw
  aplay --format=S16_LE --rate=16k --file-type=raw out.raw
