Samples and bindings for the Google Assistant API
Project description
This repository contains a Python sample for the Google Assistant API.
See Getting Started with the Raspberry Pi 3 for instructions on how to run the sample on supported hardware.
Prerequisites
Python (3.x prefered)
Google API Console Project w/ Google Assistant API enabled.
OAuth client ID credentials with application type Other.
Use a new virtualenv (recommended):
# python3 (recommended) sudo apt-get update sudo apt-get install python3-dev python3-venv python3 -m venv env env/bin/python -m pip install --upgrade pip setuptools source env/bin/activate # python2 sudo apt-get update sudo apt-get install python-dev python-virtualenv virtualenv env --no-site-packages env/bin/python -m pip install --upgrade pip setuptools source env/bin/activate
Setup
Install the sample dependencies:
sudo apt-get install portaudio19-dev libffi-dev libssl-dev
Install the latest Google Assistant SDK and samples package from PyPI:
python -m pip install --upgrade google-assistant-sdk[samples]
Or if working from this repository’s sources, run:
python -m pip install --upgrade -e ".[samples]"
Authorize access to the Google Assistant API:
python -m googlesamples.assistant.auth_helpers --client-secrets client_secret_XXXX.json Please go to this URL: ... Enter the authorization code:
Verify audio setup:
# Record a 5 sec sample and play it back python -m googlesamples.assistant.audio_helpers
Run the Sample
Record a voice query and the program should play back the Google Assistant’s answer:
python -m googlesamples.assistant
Record and send pre-recorded audio to the Assistant:
python -m googlesamples.assistant -i in.wav
Save Assistant response to a file:
python -m googlesamples.assistant -o out.wav
Troubleshooting
Verify 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
Run the sample with verbose logging enabled:
python -m googlesamples.assistant --verbose
