Researchers have developed a novel speech-LLM system for the 2nd MLC-SLM Challenge, focusing on automatic speech recognition and speaker diarization. Their system, which combines DiariZen-Large-s80 segmentation with CAM++ speaker clustering and a LoRA-adapted omniASR LLM 7B v2 recognizer, achieved a macro tcpMER of 29.27% on the development set, significantly outperforming the official baseline. The study also analyzed the impact of engineering choices, finding that embedding-based speaker clustering was more effective than end-to-end approaches and that overlap-aware segmentation could inadvertently increase tcpMER.
