was designed to enable users to build their own voice control assistant
using a Raspberry Pi.
Here are the key components and steps involved in creating a Goog-
le AIY Voice Kit with Raspberry Pi:

• Hardware Components: The Raspberry Pi acts as the central com-
puting unit that runs the AIY software, while the Voice hardware
attached on top (HAT) is an accessory board that includes neces-
sary hardware for audio input and output. A speaker is provided
for audio output of the AI assistant’s responses, and a microphone
captures user voice commands. Additionally, a button allows us-
ers to trigger the AI assistant with a physical button.
• Software and Libraries: The Google Assistant SDK is a software
development kit provided by Google that enables developers to
integrate Google Assistant functionality into their projects. Rasp-
bian OS is the recommended operating system for Raspberry Pi,
and Google provides a set of software packages and configurations
tailored for the AIY Voice Kit through their AIY Projects software.
• Assembly and Configuration: Users need to assemble the hardware
components, which includes connecting the Voice HAT to the Rasp-
berry Pi. Once assembled, users can install the required software
packages and configure the system to work with the AIY Voice Kit.
• Integration with Google Assistant: To integrate with Google Assis-
tant, users must set up a Google Cloud Platform (GCP) project to
obtain API credentials. These credentials are then used to config-
ure the AIY kit, allowing it to communicate with Google’s servers.
