The Nana and Poppy Project

This is a customized Google Assistant with push button activation. What makes it special is here.

Configuration

Follow the instructions for the Google AIY Voice Kit and get an initial working configuration. Next, install python modules for the Open Weather Map API wrapper and the inflect project.

pip3 install inflect pyowm

Copy the contents of this repository to /home/pi on the Raspberry Pi. The assistant.json file should match your Google Assistant API credentials and ids.

Configure Raspberry Pi

At a minimum, you'll need to set the timezone and WiFi networking options. Run the Raspberry Pi Software Configuration Tool ...

sudo raspi-config

Change the default password for user pi from raspberry to something else you can remember. Enter the WiFi credentials under "Network Options". Finally, set the desired timezone under "Localisation Options->Change Timezone".

Get the audio clips

The phrase-list.txt file contains all the words and phrases for which you'll need audio clips. Make sure that these are in Waveform Audio File Format (WAV) and that the filenames exactly match the words and phrases in the phrase-list.txt file, sans the .wav extension.

You can confirm the audio clips are fully populated and properly named using the check-file.sh bash script.

./check-files.sh child1 wav
./check-files.sh child2 wav

Enable service start at boot

Install the service unit file and enable the service to start when the device boots.

sudo ln -s `pwd`/assistant_grpc_demo.service /lib/systemd/system
sudo systemctl daemon-reload
sudo systemctl enable assistant_grpc_demo.service
