Reading Emotions in the Token Space: Discriminative Adaptation of SpeechLLMs for Emotion Recognition

SpeechLLMs have shown strong potential for emotion recognition, yet they read the predicted emotion off a generative decoder not suited for classification: it can emit labels outside the target set and favors frequent classes. We propose a discriminative adaptation that reads the final prompt token's hidden state throu...

Less can be More: What Aspects of Speech Drive End-of-Turn Detection

These findings suggest that turn-taking is primarily conveyed through intonation and silence patterns rather than semantic completeness, enabling faster and more reliable systems without expensive text inference.

LLMs Get Smarter from Targeted Synthetic Multilingual Data

HOTFIXR: Hardness Optimized Training data For Improving X-Lingual Reasoning is a data generation framework that uses models to probe and learn a student model's multilingual weaknesses, and generates data to mitigate them that can improve multilingual performance.

When Synthetic Speech Is All You Have: Better Call GRPO

This work shows that Group Relative Policy Optimization (GRPO) extracts far more from the same synthetic speech than SFT, and traces the gain to behavior rather than representation: GRPO reduces insertion errors by improving stopping calibration and speech-to-text alignment by better anchoring attention to audio, leavi...
