Samples and Tools the Google Assistant SDK

Google Assistant SDK for devices - 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[samples]

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 the Actions Console project and the Google account <httpsb://developers.google.com/assistant/sdk/guides/service/python/embed/config-dev-project-and-account>`_.
- Follow the steps to `register a new device model and download the client secrets file <https://developers.google.com/assistant/sdk/guides/service/python/embed/register-device>`_.
- Generate device credentials using ``google-oauthlib-tool``:

pip install --upgrade google-auth-oauthlib[tool]
google-oauthlib-tool --client-secrets path/to/credentials.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-devicetool
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This tool allows you to register Google Assistant device models and
instances and associate them with Device Actions traits.

- Install the sample's dependencies::

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

- Show the CLI tool usage::

googlesamples-assistant-devicetool --help

- Register a new device model and new device instance (after replacing the 'placeholder values' between quotes)::

googlesamples-assistant-devicetool --project-id PROJECT_ID register --model 'my-model-identifier' \
--type LIGHT --trait action.devices.traits.OnOff \
--manufacturer 'Assistant SDK developer' \
--product-name 'Assistant SDK light' \
--description 'Assistant SDK light device' \
--device 'my-device-identifier' \
--nickname 'My Assistant Light'

- Register or overwrite the device model with the supported traits (after replacing the 'placeholder values' between quotes)::

googlesamples-assistant-devicetool --project-id PROJECT_ID register-model --model 'my-model-identifier' \
--type LIGHT --trait action.devices.traits.OnOff \
--manufacturer 'Assistant SDK developer' \
--product-name 'Assistant SDK light' \
--description 'Assistant SDK light device'

*Note: The model identifier must be globally unique.*

- Register or overwrite the device instance using the device model (after replacing the 'placeholder values' between quotes)::

googlesamples-assistant-devicetool --project-id PROJECT_ID register-device --device 'my-device-identifier' \
--model 'my-model-identifier' \
--nickname 'My Assistant Light'

*Note: The device instance identifier should be unique within the Google Developer Project associated with the device.*

- Verify that the device model and instance have been registered correctly::

googlesamples-assistant-devicetool --project-id PROJECT_ID get --model 'my-model-identifier'
googlesamples-assistant-devicetool --project-id PROJECT_ID get --device 'my-device-identifier'

- List all device models and instances::

googlesamples-assistant-devicetool --project-id PROJECT_ID list --model
googlesamples-assistant-devicetool --project-id PROJECT_ID list --device

googlesamples-assistant-pushtotalk
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This reference sample implements a simple but functional client for the `Google Assistant Service`_.

- Install the sample's dependencies::

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

- Run the push to talk sample. The sample records a voice query after a key press and plays back the Google Assistant's answer::

googlesamples-assistant-pushtotalk --device-model-id 'my-device-model' --device-id 'my-device-identifier'

- Try some Google Assistant voice query like "What time is it?" or "Who am I?".

- Try a device action query like "Turn <nickname / model product name> on".

- Run in verbose mode to see the gRPC communication with the Google Assistant API::

googlesamples-assistant-pushtotalk --device-model-id 'my-device-model' --device-id 'my-device-identifier' -v

Also see sample `README <googlesamples/assistant/grpc/README.rst`_.

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]

- Try the hotword sample::

googlesamples-assistant-hotword --device_model_id 'my-model-identifier'

Also see sample `README <googlesamples/assistant/library/README.rst`_.
