ParaBridge: Bridging Paralinguistic Perception and Dialogue Behavior in Speech Language Models

ParaBridge is a self‑distillation method that uses a temporary paralinguistic instruction scaffold during training to teach a speech language model when non‑lexical cues should influence dialogue responses. By providing dense, full‑vocabulary next‑token targets from the scaffolded view while the scaffold‑free model generates its own replies, ParaBridge stabilizes inference‑time behavior without requiring curated dialogues or external reward models. Experiments on Qwen3‑Omni show significant gains on safety and empathy benchmarks while preserving general performance across multiple tests.

When to Call an LLM: A Confidence-Gated Hybrid for Cost-Effective Emotion Recognition in Conversational AI

The paper evaluates three approaches for emotion recognition in conversation— a low‑cost stacked ensemble, an off‑the‑shelf LLM prompt, and a confidence‑gated hybrid that escalates only uncertain ensemble predictions to the LLM. Across three datasets (IEMOCAP, MELD, CMU‑MOSI), the hybrid consistently outperforms each pure system, achieving higher weighted F1 scores while routing most traffic through the inexpensive ensemble. This results in significant cost savings (≈$10‑85 per million utterances) and provides an interpretable escalation signal tied to emotion or sentiment shifts.
