Show HN: Jarvis, a voice assistant that never leaves your network (github.com)

Jarvis, a new self-hosted voice assistant, has been announced, offering a fully local solution that operates entirely on users' hardware rather than relying on cloud services. Key features include built-in wake word detection, speech-to-text, text-to-speech, and speaker identification, all performed locally to enhance privacy and performance. Users can access 20 core commands, with an additional 24 readily available from a community-driven store called the Pantry. Jarvis allows for easy extension through the AI Forge, which enables users to create and publish new commands using natural language descriptions. The significance of Jarvis lies in its commitment to privacy and independence from cloud-based voice assistants, addressing growing concerns over data security in AI-driven technologies. By running on local systems and allowing users to bring their own language models, Jarvis provides flexibility between privacy and convenience. Technical innovations, such as prefix-cache-aware prompts and local-first routing, enable fast response times, achieving full voice command execution in approximately 2.4 seconds. The use of affordable edge devices like Raspberry Pi Zero further democratizes access, making advanced voice assistant capabilities widely available without recurring costs or data compromise.
