Set up the Azure Percept Audio device


Retirement of Azure Percept DK:

Update 22 February 2023: A firmware update for the Percept DK Vision and Audio accessory components (also known as Vision and Audio SOM) is now available here, and will enable the accessory components to continue functioning beyond the retirement date.

The Azure Percept public preview will be evolving to support new edge device platforms and developer experiences. As part of this evolution the Azure Percept DK and Audio Accessory and associated supporting Azure services for the Percept DK will be retired March 30th, 2023.

Effective March 30th, 2023, the Azure Percept DK and Audio Accessory will no longer be supported by any Azure services including Azure Percept Studio, OS updates, containers updates, view web stream, and Custom Vision integration. Microsoft will no longer provide customer success support and any associated supporting services. For more information, please visit the Retirement Notice Blog Post.

Azure Percept Audio works out of the box with Azure Percept DK. No unique setup is required.


  • Azure Percept DK (devkit)
  • Azure Percept Audio
  • Azure subscription
  • Azure Percept DK setup experience: you connected your devkit to a Wi-Fi network, created an IoT Hub, and connected your devkit to the IoT Hub
  • Speaker or headphones that can connect to a 3.5-mm audio jack (optional)

Connecting your devices

  1. Connect the Azure Percept Audio device to the Azure Percept DK carrier board with the included Micro USB to USB Type-A cable. Connect the Micro USB end of the cable to the Audio interposer (developer) board and the Type-A end to the Percept DK carrier board.

  2. (Optional) connect your speaker or headphones to your Azure Percept Audio device via the audio jack, labeled "Line Out." This will allow you to hear audio responses.

  3. Power on the dev kit by connecting it to the power adaptor. LED L02 will change to blinking white, which indicates that the device was powered on and is authenticating.

  4. Wait for the authentication process to complete, which takes up to 5 minutes.

  5. You're ready to begin prototyping when you see one of the following LED states:

    • LED L02 will change to solid white, indicating that the authentication is complete and the devkit is configured without a keyword.
    • All three LEDs turn blue, indicating that the authentication is complete and the devkit is configured with a keyword.
