Proactive for Uncertainty: Cause-Aware Error Diagnosis and Interactive Clarification for Spoken Dialogue Systems

arXiv:2605.25404v1 Announce Type: new Abstract: Cascaded Automatic Speech Recognition -- Large Language Model (ASR-LLM) pipelines remain popular for industrial Spoken Dialogue Systems (SDS), primarily because their decoupled design ensures perceptual verifiability. However, cascaded systems suffer from error propagation, as transcription failures inevitably cascade to subsequent components, thereby degrading the final interaction quality. Although ASR confidence scores offer a simple filter for unreliable inputs, this approach is fundamentally limited because it typically fails to detect delet
The paper outlines a method using LLMs to proactively diagnose and clarify errors in spoken dialogue systems, addressing a critical challenge in their deployment at industrial scale.
Improving the reliability and conversational quality of spoken dialogue systems is crucial for widespread adoption and for advancing the utility of AI agents in real-world applications.
This approach reduces error propagation in cascaded ASR-LLM systems, enabling more robust and user-friendly interactions by actively identifying and mitigating transcription failures.
