Using the Raspberry Pi 5 and ChatGPT, he developed a custom voice assistant capable of interpreting and responding to commands.

The project’s concept is simple, but its execution required considerable effort. The Raspberry Pi captures audio via a microphone, and ChatGPT processes and interprets the input to provide appropriate responses, which are then played back through a speaker.

Functionally, it resembles commercial systems like Alexa, but with a key difference: it doesn’t rely on Amazon’s servers, thus ensuring user privacy.

With sufficient processing power, the Raspberry Pi 5 can handle the assistant’s tasks, though it requires a fan to prevent overheating, a common issue for this model. Suryatejadev programmed the device to respond to a “wake word” – in this case, “Corgi.” When it hears the word, the Pi “barks” in response. Users can also use a smartphone to issue commands by installing "Easy Voice Recorder" and syncing it with Raspberry Pi via "Syncthing."

Suryatejadev has made the project’s source code publicly available, sharing details on the development process. The Python script he wrote manages audio processing and interaction with ChatGPT. The full source code is accessible on GitHub and the project’s official page here.
