Analyzing Error Propagation in Korean Spoken QA with ASR-LLM Cascades

In three linesStudy of ASR error propagation in ASR-LLM cascades for Korean spoken question answering. Speech recognition errors cause semantic failures that conventional ASR metrics cannot fully capture. Single-character Korean ASR errors create a distinct failure channel. A large audio language model outperforms the ASR-LLM pipeline on noisy Korean SQA.
