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)
