Before starting the set up of MATRIX Voice Google Assistant it would be good if you know a little bit about the components and boards used in this project. You can either read it or just start the tutorial section. Let us get familiarized.
Raspberry Pi is small credit card sized, light weight and compact computer available which is used by both professions, hobbyist and of course hackers alike. This mini computer can do (almost) any thing a normal linux machine can do. It is widely used in various industries, robotics, home automation projects.
This little development board consist of a radial array of 8 MEMS microphones, 18 RGBW LED’s and 64 GPIO pins, which is linked to a Xilinx Spartan6 FPGA and 64 Mbit SDRAM. This provides the hobbyists and developers a wonderful opportunity to add custom voice and hardware-accelerated machine learning technology In no time.
An advanced version of this MATRIX Voice is also available employing a ESP32 Wi-Fi / BT chipset which will enable users to easily connect to the network or other devices via WiFi and Bluetooth in no time.
MATRIX Voice Google Assistant Tutorial
Step 1 : Setting Up Raspberry Pi
Download and burn latest Raspbian image to a micro SD card and insert it into the raspberry Pi.
Now power it up with a power adapter that can provide at least 2.5 Ampere. Now fire up your terminal and create a password for the user ‘pi’ by executing the command
sudo passwd pi
Connect your Raspberry Pi to a WiFi router or Wired network and make sure it is connected by checking whether it is getting an IP address from the switch.
Now perform and update and upgrade by running
sudo apt update -y
sudo apt upgrade -y
Step 2 : Adding the Repositories
In order to set up Google Assistant in your MATRIX Voice, you should start by installing the right tools. First we will install the MATRIX Software by adding the right repositories. Enter the below commands to install MATRIX Software
Go to Actions Console and select the project you created on the upper part of the screen.
From the left navigation bar, click on the Connected properties.
Click on the DEVICE MODELS tab and Click on the REGISTER MODEL button.
Fill up all the information and Click REGISTER MODEL. when you are finished
Download credentials.json file to your computer and place it in your Raspberry Pi in which MATRIX Voice Google Assistant will be running.
It is recomended not to rename this file and keep it under /home/pi folder.
Download this file and transfer it to the device. Click NEXT.
Before installing the SDK, it will be a smarter move to isolate system packages from packages that we are about to install. For that, we will set up a virtual environment for us to tinker with.
Note: Run these codes from /home/pi directory otherwise it wont work.
Setup Python Virtyual Environment using the following commands
If everything is done correctly, you should see a URL displayed in the terminal some what like this:
Please visit this URL to authorize this application: https://...
Enter the authorization code:
Now all you have to do is copy the entire URL, open up a browser and paste the URL in the address bar and hit enter. It will ask you to login to the Google Account that is linked with the developer project and as you for your approval.
Once you approve the request, you will be provided with a Key. Copy the key and Paste it in the Terminal. If everything went well, you should see something like this in the Terminal.
Now you can interact with your MATRIX Voice Google Assistant.
Try asking the usual question –
Hey Google, Whats the time now?
Hey Google, How is the weather outside?
