Google Assistant SDK Experiments

Raspberry Pi + Google Assistant SDK

(With Sound & Automatic Turn On)

An extension of the basic Google Assistant + Raspberry Pi demo with instructions for automatically turning it on with the Raspberry Pi and to provide audio feedback when the user talks to the device.

Step 0: Setup Assistant on Pi

• Follow https://developers.google.com/assistant/sdk/prototype/getting-started-pi-python/
• Clone this repo in the home directory.

Step 1: Install audio library

Run sudo apt-get install sox libsox-fmt-all

Step 2: Startup script

Make a script called startup.sh with the following content.

#!/bin/bash

echo "Running Google Assistant…"
source env/bin/activate
python /home/pi/PiAssistant/assistant.py &

Step 3: Run the script on startup

• To schedule a task on reboot we need a GUI for Corn, install it using sudo apt-get install gnome-schedule. Read more here.
• Execute crontab -e and add the following two lines at the end of the file – one for setting the volume to a desirable level and another to start the assistant.

amixer set Master 80%
@reboot sleep 10 && /usr/bin/zsh -e "/home/pi/startup.sh"

• If you do not know the name of the device (Master in the example) run amixer to get the name of the device and set a volume you want the Pi to boot up with.
• Use the terminal client of your choosing, i prefer having zsh.
