# google-assistant-hotword-raspi

Simple Google Assistant with hotword activation from Snowboy setup for RaspberryPi 1 and Zero W.

# Setup

#### 1. [Google Assistant Python setup on Raspbery Pi](https://developers.google.com/assistant/sdk/prototype/getting-started-pi-python/)

  * [Configure a Developer Project and Account Settings](https://developers.google.com/assistant/sdk/prototype/getting-started-pi-python/config-dev-project-and-account)

  * [Configure and Test the Audio](https://developers.google.com/assistant/sdk/prototype/getting-started-pi-python/configure-audio)

  * Setup virtual environment

    ```

    -   (Recommended) For Python 3:

    

        sudo apt-get update

        sudo apt-get install python3-dev python3-venv

        python3 -m venv env

        env/bin/python -m pip install pip setuptools --upgrade

        source env/bin/activate

    

    -   For Python 2:

    

        sudo apt-get update

        sudo apt-get install python-dev python-virtualenv

        virtualenv env --no-site-packages

        env/bin/pip install pip setuptools --upgrade

        source env/bin/activate

    ```

  * Install dependencies

    `sudo apt-get install portaudio19-dev libffi-dev libssl-dev`

  * Install Google Assistant SDK + Samples

    ` python -m pip install google-assistant-sdk[samples]`

  * Get 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`

  * Test using the sample

    `python -m googlesamples.assistant`

    Issue commands after pressing `enter` and if you did all the steps above Google Assistant should respond.

***PS** On Raspberry Pi Zero W this setup takes about 30-40 minutes.*

#### 2. [Snowboy Python setup on Pi](http://docs.kitt.ai/snowboy/) - [Github](https://github.com/Kitt-AI/snowboy)

  * (Optional - The required files are already in this repo) Download Snowboy [compiled library for all versions of Pi + demo](https://s3-us-west-2.amazonaws.com/snowboy/snowboy-releases/rpi-arm-raspbian-8.0-1.2.0.tar.bz2)

  *  Install dependencies

    `sudo apt-get install python-pyaudio python3-pyaudio sox`

  * Install BLAS

    `sudo apt-get install libatlas-base-dev`

  * Install PyAudio

    `pip install pyaudio`

    You should be able to recored audio using:

    `rec temp.wav`

***PS** For Python 3 rename `_snowboydetect.so_py3` to `_snowboydetect.so`.*

#### Train your own hotwords or download existing ones from https://snowboy.kitt.ai/

#### 3. Run `gassistant.py` and you should have a working Google Assistant with hotword activation

    `python gassistant.py models/ok_google.pmdl`
