Once hardware and software basic setup complete. We can move ahead for Alexa on raspberry pi setup.


Firstly open a terminal window on raspbian operating system desktop. Then type the following commands.

$ cd /home/pi/

$ sudo apt-get update

After updating all packages up to date now ready to integrate AVS (Alexa voice service).

How to integrate Alexa with Raspberry Pi

Before download and build AVS device SDK needs to register a device and open a developer account.

So that can create a device config file (config.json) that contains client ID and client secrets. Also need to create a security profile.

After doing all these actions refresh the token to authorize to access Alexa.

But first thing first open or create an amazon Alexa developer account.

If you are creating an account first time then need to fill in all the details like first and last name, email and phone number, location, address, etc.


Need to define your role in the team. Because from this account you can work as a developer team.

After create account or log-in and you will see welcome screen.


Just click on get started then click on products as shown below.


Now click on ADD NEW PRODUCT at the right top of the screen. Enter the details to set up Alexa on raspberry pi.

  1. Enter product name AVS Tutorial Project or any name of your choice.
  2. The next option is Product ID .enter ID for your product.
  3. In Product Type select Device with Alexa built-in.
  4. Will your device use a compression app? select No.
  5. The product category selects Other.
  6. In specification provide value like a prototype.
  7. Can write the description of your choice.
  8. select the next option Hand Free.
  9. Skip the next step or upload an image of your choice 142×130 px.
  10. Want to distribute product select No.
  11. The device listed for Alexa business? select No.
  12. Device associated with Alexa IoT core select No.
  13. product for children also selects No.

Now after clicking on the next page will display. Here need to create a security profile for Alexa on raspberry pi.


Click on CREATE NEW PROFILE then type security profile name and description.

Choose Other devices and platforms from the Web – Android/Kindle – iOS – Other devices and platforms from the menu.

Then click on download for downloading the config.json file. Copy jason.config file and paste into home/pi/ directory.


Download the SDK configuration scripts for Alexa On Raspberry Pi

Open /home/pi/ directory in terminal and enter the following commands.

wget \
wget \

Note: Above commands should type carefully because it is case sensitive. In case receive any error then verify the command.

As soon as the download finished again command prompt will appear.

Now need to run script from the command prompt with some additional arguments.

Script builds SDK and install dependencies for following functions.

  • Maintain an HTTP/2 connection with AVS.
  • Play Alexa TTS and music.
  • Record audio from the microphone.
  • Store records in a database (persistent storage).

Type the following command and press enter.

cd /home/pi/
sudo bash config.json [-s 123456]

There are two arguments with The first one is config.json file which we create and download earlier. It has device details and security configuration.

The second argument is Device Serial Number which is unique for each instance of SDK. If you don’t supply SDK generate default value 123456.

From here almost halfway is finished to install Alexa on raspberry pi.


The next screen will display AVS Device SDK Raspberry Pi Term and Agreements. Read it and type AGREE then press the return key.

From this point it takes around twenty minutes to finish.

During installation at some point, SDK setup stops and ask to accept sensory wake word’s term and conditions. Type yes and press return to proceed.

The Wake Word Engine (WWE) Alexa on raspberry pi from sensory compares incoming audio to an onboard model of Alexa wake word.

Also initiates the communication of voice to the server when triggered.

For Prototype Device WWE (wake word engine) is free. But for commercial devices need to buy licenses.

Get refresh token for Alexa on raspberry pi

Once completion message received on the terminal as mentioned in the picture.


In case received any error or process stops then you can start it over. The setup process will install the rest of the SDK packages.

Now run the sample app using the following command.

Before running the command make sure all input/output devices (microphone and speaker) should be attached with raspberry pi.

cd /home/pi/
sudo bash

After that Alexa on the raspberry pi is running. All the AVS device SDK installed and credentials loaded.

But the device still needs a refresh token to maintain communication with Alexa voice service.

For the production of Alexa enabled products can use the same Client ID and Product ID.

But each user required a unique refresh token for AVS identification via LWA( login with amazon).

Once the above command starts running then need to scroll upside all the debugging messages and search for authorization code as mention in the image.


Note down the code which is unique for each device.

Click on ‘‘ login via LWA (login with amazon) and register your device by entering this code.

It might take around thirty-second CBLAuthDelegate to successfully get a refresh token from LWA ( Login with Amazon).


After punching the code and press continue will ask to allow AWS (Alexa voice service) and Alexa account connection.

Click on allow as shown in the image.


At last the success message will come up in new page. walla it’s time to talk with alexa on raspberry pi.


Talk with Alexa on raspberry pi

Here now first Alexa based prototype project is ready for testing. Running after few debugging messages you will see the IDLE message.

Which means the device is ready to receive voice commands.

While called Alexa bunch of messages start to scroll on the terminal which indicates device status changed IDLE to Listening mode.

In case I never changed from IDLE to Listening mode then need to verify the microphone is working properly or not?

Sometimes keep mouth close to the microphone started to respond because of less sensitive microphones.

Use wake-word Alexa and will see the status changed to Listening now after wake-word give the command for example “Alexa what is time now”.

After command again status will change it will show in terminal like Thinking then will show speaking when Alexa will start to speak.

  • Say “Alexa”, then ask “What time is it?”
  • Say “Alexa”, then say “Who is Eon Musk?”
  • Say “Alexa”, then say “How do you say friend in Spenish”

Multi turn interaction with Alexa on raspberry pi

If you ask Alexa to set an alarm on 12 then it will ask for am or pm.

While you instruct about am or pm you don’t need to call Alexa at the starting of the phrase again.

This is known as multi turn speech interaction.
