rustvani (currently v0.30 on crates.io) is a pure-Rust voice agent framework implementing a full VAD -> STT -> LLM -> TTS pipeline, including a custom protocol (RAVI), a multi-agent bus, and a node-based conversation flow engine (Dhara). It targets low-latency, production-grade voice AI, with support for vernacular language pipelines.
