Voice Activated Google Assistant for Raspberry Pi

On this Instructablel I will be showing you how you can allow voice activation on your Google Assistant on your Raspberry Pi.

It's way more simple that you'll thought. Hope that you like it and thanks for reading this.

Step 1: What You'll Need

• A Raspberry Pi
• An USB Microphone
• Google Assistant's API
• A few dependencies

Step 2: Set Everything Up

Log into your Raspbian with PIXL Desktop.

Open up a Web Browser and go to "console.cloud.google.com/project"

Log into your Google Account.

Click on "CREATE PROJECT"

Give it any name you like and click "Create"

Wait for your project to show and then click the three dots on the project's name.

Click on the three little lines at the top left of the page, then select "API Manager"

Click on the dropdown menu.

Hit all, then select your project.

Type "Google assistant" on the search bar, this will make the searching process a lot quicker and easier.

Click on the "Google Assistant API" and then click "Enable"

Step 3: OAuth Key

Go to the bar on the left and select "Credentials" and then click on the "OAuth Consent Screen"

Hit on "Create Credentials", then select "OAuth client ID"

In the next screen, choose "Other" and give it any name that you want.

Hit "Ok" and then move your mouse over to an arrow pointing down at the right of the screen, click on it to download your Credentials file.

Step 4: Enable Permissions

Head over to "myaccount.google/activitycontrols"

Scroll down and activate the following controls:

• Web & App Activity
• Location History
• Device Information
• Voice & Audio Activity

Step 5: Download and Install Dependencies

Open up the Command Prompt.

Update your System.

Once it finishes, type in "sudo apt-get install python3-dev python3-venv" press "Enter" and wait for it to finish.

When the download finishes, type in "python3 -m venv env"

Once you enabled that, type "env/bin/python -m pip install –upgrade pip setuptools –upgrade" and press "Enter"

Type "source env/bin/activate" to get into the enviroment.

Step 6: Run Your Assistant

Type in "python -m pip install –upgrade https://github.com/googlesamples/assistant-sdk-py... and then press "Enter"

After it finishes downloading, run the OAuth tool by typing "python -m pip install –upgrade google-auth-oauthlib[tool]"

Type in "google-oauthlib-tool –client-secrets /home/pi/Downloads/client_secret_client-idxxx.json –scope https://www.googleapis.com/auth/assistant-sdk-pro... –save –headless". Replace "idxxx" with your project's ID number.

An URL will be displayed, right click on it, select "Copy" then paste it on your browser.

Copy the Auth key.

Go to the Terminal, right lick on it and then hit "Paste" to paste the Authentication Key.

Step 7: Start Google Assistant

You can start enjoying your Google Assistant with voice recognition by typing "google-assistant-demo"

Enjoy your shiny new voice recognition on your Raspberry Pi-based Google Assistant.

And that's it, I hope that you liked this Instructable, if you have any problem, suggestion or comment, leave it down below.

Thanks SO much for posting this. Unfortunately, I was trying it on a Pi Zero W, and I found out in the last step that the SDK only supports ARM7L, not the ARM6L used in the Zero. It sucks, but I was looking for an excuse to buy a Pi 3b, and now I have one.

A couple of notes to help others where I stumbled:

1) in the command "env/bin/python -m pip install –upgrade pip setuptools –upgrade" there are 2 hyphens before the word "upgrade". It was really hard to see in the proportionally spaced font and took me a lot of reading to find my mistake.

2) the command "python -m pip install –upgrade https://github.com/googlesamples/assistant-sdk-py..." is truncated. Right click on the link and select "Copy link address" and paste it into the command line (I tried to enter the full address here in the comment, but the editor keeps truncating it too, even if I try to unlink it!). Again, there are 2 hyphens before the words "upgrade".

3) similarly, the command "google-oauthlib-tool –client-secrets /home/pi/Downloads/client_secret_client-idxxx.json –scope https://www.googleapis.com/auth/assistant-sdk-pro..." is also truncated. Just copy and paste the link address into the command line.
