Contributed to the xinnan-tech/xiaozhi-esp32-server project by building and refining real-time speech and language processing features, focusing on robust API integration and backend development. Delivered MQTT gateway support, PaddleSpeech and Aliyun TTS/ASR integration, and performance testing frameworks for streaming audio and large language models. Enhanced reliability through configuration management, database-backed settings, and protocol compatibility across UDP, WebSocket, and MQTT. Used Python, C, and SQL to implement asynchronous audio processing, multilingual ASR, and domain-specific LLM behavior control. Addressed deployment and usability challenges by updating documentation, refactoring streaming logic, and stabilizing configuration delivery for scalable, multilingual IoT deployments.
In April 2026, the xiaozhi-esp32-server project delivered two key features that strengthen business value and reliability, with focused improvements in LLM behavior control and real-time ASR streaming.

December 2025: Delivered four major capabilities in xiaozhi-esp32-server that expand testing coverage, improve user responsiveness, and broaden language support: (1) Aliyun TTS support in performance testing tools for streaming TTS; (2) Direct talk-button triggered ASR without VAD for immediate voice recognition; (3) ASR streaming text handling improvements with refactors in ASRProvider and wake-up logic; (4) Aliyun BLStream ASR provider with multilingual support, semantic punctuation, and disfluency removal. These changes include targeted fixes to wake-up state handling and streaming text updates, driving faster iteration, better accuracy, and expanded market reach.
