EchoKit: Educational Voice AI Toolkit for Students and Builders
EchoKit is more than a voice AI assistant – it's a complete learning platform that teaches you how to build AI agent systems from the ground up. Perfect for students, educators, and anyone who wants to understand AI by building it themselves.
Unlike black-box AI systems, every component of EchoKit is open-source and documented. Learn embedded programming, audio processing, voice detection, agentic AI, LLMs, ASR / STT, TTS, voice-cloning, MCP integration, and real-time networking by working with production-quality code.
Fully assembled AI assistant in a very small box, together with full-stack open-source software, documentation, and learning materials. Shipping internationally.
What You'll Learn
- Build embedded systems with Rust on ESP32 hardware
- Implement real-time audio processing and Voice Activity Detection
- Integrate multiple AI models (LLMs, speech recognition, text-to-speech)
- Create WebSocket-based real-time AI services
- Design agentic systems with tool use and knowledge retrieval
- Clone voices using GPT-SoVITS technology
- Support Model Context Protocol (MCP) for extensibility
- Deploy AI systems locally at your home or office
What Our Users Say
"EchoKit is exactly what we missed with Alexa."
"EchoKit makes it easy to create an AI-enabled voice agent, you can use the tooling like ElevenLabs, Groq or host everything locally depending on the usecase. Open source, flexible and easy to use."
Built for Learning and Teaching
EchoKit was designed from the ground up as a learning platform. Every design decision prioritizes learning opportunities, code clarity, and hands-on experience with modern AI technologies.
