Machine learning has revolutionized numerous industries in the past decade, and the release of OpenAI’s ChatGPT marked a significant turning point in the accessibility of large language models (LLMs). While concerns about computing resources, privacy, and biases persisted, recent developments have made it possible for individuals to create their own LLM-based voice assistants on a Raspberry Pi.
Setting up this voice assistant is surprisingly straightforward. With a Raspberry Pi, a USB microphone, and a speaker, you can build your own personalized LLM-based voice assistant that operates entirely locally. Gone are the worries about sending sensitive information over the internet to cloud service providers. The focus is on privacy.
Here’s how it works: upon pressing a button, you speak your request, and a microphone captures the audio. The Whisper automatic speech recognition software then converts it into a transcript. This transcript is fed into the TinyLlama-1.1B LLM, which has been conveniently packaged as a llamafile. Llamafiles are self-contained LLM-based chatbot executables that can run on various hardware architectures and operating systems. The response from the LLM is then transformed into audio using the eSpeak speech synthesizer and played through the connected speaker.
The beauty of this setup is that it can all be done offline. Your Raspberry Pi can be disconnected from the internet, ensuring the privacy of your conversations. However, it’s important to note that the processing time for a request can range from 15 seconds for simpler requests to longer durations for more complex ones.
The instructions for building this LLM-based voice assistant are easily accessible, and the entire process should take less than an hour to complete. If you have a Raspberry Pi 5, the system should perform even faster. Additionally, there are possibilities to adapt and optimize the setup for other faster single-board computers.
With the current state of open-source models and advancements in technology, the barriers to entry for creating and utilizing LLM-based voice assistants have significantly diminished. Now, individuals with technical inclinations can explore the world of LLMs, harnessing the power of machine learning on their own terms. So, why not give it a try and embark on your journey with the World’s Easiest GPT-like Voice Assistant?
