| Challenge: | Researchers have developed a sound codec that can be used as tokenizers for preserving audio data and minimizing data transmission latency. |
| Approach: | They propose to use codec-SUPERB to assess codec models across representative sound applications and signal-level metrics rooted in sound domain knowledge. |
| Outcome: | The proposed codec-SUPERB model is evaluated on selected experimental settings. |
Safety-Aware Dialogue System for Postoperative Oral Cancer Care with Structured Clarification and a Clinically Curated Dataset (2026.findings-acl)
Copied to clipboard
| Challenge: | Clinical dialogue systems can enhance patient education and follow-up care by providing brief and subjective messages that lack critical clinical context. |
| Approach: | They propose a safety-aware dialogue system that applies information-gain guided clarification before RAG-based response generation and screens user utterances for emotional distress and suicidal ideation. |
| Outcome: | The proposed system improves quality and clinical appropriateness relative to strong baselines while aligning with expert judgments on clinically concerning utterances. |
