We built a voice AI agent in Rust.
EchoKit server is an open-source framework that connects speech input, LLM reasoning, and speech output — so you can build local or hybrid voice assistants with real-time interaction. It's super easy to set up.
Current features:
1. Supports both traditional ASR → LLM → TTS pipelines and end-to-end models like Gemini Live.
2. Voice Activity Detection (VAD) for low-latency, streaming voice input.
3. MCP support for external tools.
4. Works with both ESP32 hardware and web clients.
5. Streaming TTS output for GPT-Sovits
Would love to hear what kind of projects people would build with this or any feedback.
