Build Notes
This project is a fully local, privacy-first alternative to cloud-based voice assistants. By hosting intelligence on-site, voice data never leaves the home network while still delivering modern AI response speeds.
Infrastructure is distributed for performance and reliability: a Proxmox VM running Home Assistant acts as the central command center; a Mac mini (M1, 16GB RAM) provides local LLM compute; and a Raspberry Pi serves as the physical interface in a custom 3D-printed mount.
Core technologies include local LLM integration for natural language understanding, openWakeWord for on-device 'Hey Jarvis' wake detection, and a Jabra Speak 4 for microphone pickup and response output.
Key benefits: near-zero latency from local processing, full data sovereignty for voice and smart-home telemetry, and sustainable reuse of existing hardware into a high-performance automation suite.
