Researchers have developed ORCA, a novel model-based approach for assessing the correctness of open-ended responses from large audio language models (LALMs). This system utilizes a three-stage annotation pipeline involving human judgment, structured feedback, and human-AI correction to generate a dataset of over 9,600 annotations. ORCA models have demonstrated strong performance, achieving a Spearman correlation of 0.91 with human correctness ratings on known benchmarks and generalizing to new benchmarks with a score of 0.85, outperforming models like Gemini 2.5 Flash.
