Home Assistant Voice Preview Edition

Home Assistant Voice Preview Edition is an open-source, privacy-focused voice assistant designed to seamlessly connect with Home Assistant and give you a glimpse of the future of voice control today. With an advanced audio processor and dual microphones, it captures your commands and controls your devices. Tactile buttons, an injection-molded case, and an LED ring contribute to its premium feel, allowing it to blend naturally into any home.

Note: Home Assistant Voice Preview Edition requires Home Assistant to operate. Weaker Home Assistant hardware may result in slower voice processing. If you have less powerful Home Assistant hardware, it’s recommended to offload speech processing to Home Assistant Cloud.
