Pi 5 Voice Assistant Kit
Build Your Own Offline Voice Assistant with Raspberry Pi 5 Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a voice assistant that never phones home—every word you speak stays inside the room, processed instantly on a single board. This kit puts Whisper speech-to-text, Ollama’s local large language model, and Piper’s natural text-to-speech engine onto a Raspberry Pi 5, letting you build a completely offline conversational AI that you control end to end.
What You'll Build
You'll assemble a standalone device that listens through an I2S microphone, transcribes your speech on-device with no cloud delay, generates intelligent answers locally, and speaks them through a clear 3W speaker. The result is a private, always-available assistant you can query for facts, project help, or even coding suggestions—without depending on an internet connection.
What You'll Learn
- Set up Raspberry Pi 5 and NVMe SSD for fast model storage and boot
- Interface I2S MEMS microphones and Class‑D amplifiers for low‑latency audio I/O
- Deploy Whisper STT on edge hardware and fine‑tune for real‑time transcription
- Run Ollama with small language models and integrate them into a spoken dialogue pipeline

Who This Kit Is For
B.Tech ECE and CSE students building offline AI projects, Smart India Hackathon teams prototyping voice‑based rural solutions, CBSE Class 12 students curious about generative AI, and ATL Tinkering Lab mentors will all find this kit purposeful. If you’re tired of cloud‑dependent assistants and want a hands‑on understanding of how large language models work at the edge, this bundle delivers everything you need in one box.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Your kit includes a QR code linking to an AI companion that walks you through wiring, driver setup, and software configuration step by step. If you still need human help, our WhatsApp support responds within a working day.
Can I use this kit without any internet connection?
Yes. After the initial model download (guided by the AI companion), Whisper, Ollama, and Piper all run entirely offline. The assistant works in rooms with no WiFi, ideal for privacy and remote locations.
What kind of conversations can the assistant handle?
You can load open‑source models like Mistral, Phi, or LLaMA onto the NVMe SSD via Ollama. The assistant will answer general knowledge queries, debug code, suggest project ideas, or even control home‑automation routines if you expand the setup later.
Is this kit compatible with other Raspberry Pi models?
The kit is specifically designed for Raspberry Pi 5. The M.2 HAT uses the Pi 5’s PCIe connector, and the I2S audio chain is tested with the Pi 5’s 40‑pin header. It will not work directly with Pi 4 or earlier boards.
Whisper STT on Pi 5 transcribes speech, Ollama generates response, Piper TTS speaks reply — fully offline voice assistant.
