This repository contains the source code for the AIYProjects "Voice Kit". See https://aiyprojects.withgoogle.com/voice/.
If you're using Rasbian instead of Google's provided image, read HACKING.md for information on getting started.
Troubleshooting
The scripts in the checkpoints directory verify the Raspberry Pi's setup.
They can be run from the desktop shortcuts or from the terminal.
Upgrading your AIY Project
Updated May 2017
Log into your Raspberry Pi, or use the Start Dev Terminal from the desktop:
# UPDATE GOOGLE ASSISTANT SDK
cd ~/assistant-sdk-python
git checkout master
git pull origin master
# UPDATE VOICE RECOGNIZER (AKA: AIY PROJECTS)
cd ~/voice-recognizer-raspi
git checkout master
git pull origin master
# UPDATE DEPENDENCIES
cd ~/voice-recognizer-raspi
rm -rf env # needs to be rm'd w/current version of install-deps.sh
scripts/install-deps.sh
As long as you did not modify any of the files, those should have ran smoothly. If you, like me, were tinkering with the src/main.py and got a conflict, erase the changes by using git checkout <file> (make a backup if you want first with cp <file> <file>~).
Test everything is working:
sudo systemctl stop voice-recognizer.service # if you had it running
cd ~/voice-recognizer-raspi
source env/bin/activate
src/main.py
New Config Files
You may want to backup your existing config file and bring over the newest versions, then re-implement your configurations.
# back them up first
cp ~/.config/status-led.ini ~/.config/status-led.ini~
cp ~/.config/voice-recognizer.ini ~/.config/voice-recognizer.ini~
# copy the new ones over
cp ~/voice-recognizer-raspi/config/status-led.ini.default ~/.config/status-led.ini
cp ~/voice-recognizer-raspi/config/voice-recognizer.ini.default ~/.config/voice-recognizer.ini
# open and review the new options
nano ~/.config/voice-recognizer.ini
Enabling “OK Google” and “Hey Google” Hot Words
Edit the voice-recognizer.ini file as per the original setup docs:
nano ~/.config/voice-recognizer.ini
Make the trigger say “ok-google”:
# Select the trigger: gpio (default), clap, ok-google.
trigger = ok-google
NOTE: You can only have one trigger with the current project at this time.
Press CTRL-X and Y to save. Then restart the service:
sudo systemctl restart voice-recognizer.service
Now, speaking “OK Google” or “Hey Google” should work.
Setting to Auto-Start on Reboot/Power On
# UPDATE AUTO-START SERVICES ON BOOT (optional)
cd ~/voice-recognizer-raspi
sudo scripts/install-services.sh
sudo systemctl start status-led.service
sudo systemctl start status-monitor.service
sudo systemctl start voice-recognizer.service
sudo reboot
