PROFILE
Jiqunli
Jiqun Li developed and integrated Voice Activity Detection (VAD) into the audio pipeline for the 78/xiaozhi-sf32 repository, focusing on enhancing real-time communication efficiency. Using C and leveraging skills in audio processing and embedded systems, Jiqun enabled WEBRTC_USING_AEC to ensure VAD worked seamlessly with acoustic echo cancellation. The implementation involved adding VAD logic within the audio thread and adjusting buffer sizes and initialization parameters to support accurate detection. This work improved call quality by reducing unnecessary processing during silence and prepared the system for more efficient bandwidth use, with careful documentation to support future maintenance and traceability.
