ESP-AI provides a complete AI conversation solution for your development board, including IAT+LLM+TTS integration solutions for ESP32 series development boards. It can be injected into projects without affecting existing ones. By providing keys from platforms like iFlytek, Jiling, and local services, you can run the services without worrying about interactions between services or between development boards and services. The project's server-side code is based on Node.js, and the hardware code is based on Arduino IDE.

Provides a complete AI dialogue solution for your development board, including but not limited to the IAT(ASR)+LLM+TTS integration solution for the ESP32 series development boards. It is injected into the project as a dependency without affecting existing projects.

For developing the dialogue functionality of robots, you only need to prepare the IAT(ASR), LLM, and TTS services, and leave the rest to ESP-AI.

The server-side code of this project is based on Node.js, and the hardware code is based on Arduino/IDF.

✨ Features

  • ✔️ Customizable offline wake words with multiple built-in wake-up methods (voice, button, serial port, Tianwen ASRPro)
  • ✔️ Complete conversation chain: IAT (ASR) ➡️ LLM/RAG ➡️ TTS
  • ✔️ Fast response algorithms for TTS/LLM, designed to balance service cost while providing the quickest response time
  • ✔️ Supports conversation interruption
  • ✔️ Recognizes user commands (appliance control, singing, etc.) and can dynamically respond based on context
  • ✔️ Configurable
  • ✔️ Plugin-based, allowing integration with any LLM/TTS/IAT using plugins
  • ✔️ One-to-many relationship between service and clients, with independent configuration for each client (hardware)
  • ✔️ Connection supports authentication
  • ✔️ Full-chain streaming data interaction
  • ✔️ Developer platform offers: free services, visual configuration, etc.
  • ✔️ Client configuration webpage provided
  • ✔️ Easily handles high concurrency scenarios (requires Nginx for load balancing)
  • ✔️ Ready to use out of the box

🧐 Next Steps

  • [ ] 🤔 Improve accuracy of built-in offline wake-up (currently recommended to use Tianwen ASRPro)
  • [ ] 🤔 Incorporate AI into user intent inference (e.g., "Turn off the light quickly" and "Turn on the light quickly" will both be recognized as "Turn on the light" command)
  • [ ] 🤔 Online wake word generation
  • [ ] 🤔 Client OTA support
  • [ ] 🤔 Develop plugins in other languages (to avoid relying solely on Node.js for plugin development)
  • [ ] 🤔 Provide a dedicated development board (to avoid current complex wiring)

📦 Install
