Multilingual Emotion Neurons in Large Audio-Language Models

Xiutian Zhao, Philipp Koehn, Björn Schuller +1

Emotion is central to human communication, and its expression varies across languages. Large audio-language models (LALMs) achieve strong performance on multilingual speech tasks,…

TRACE-EVC: Text-Guided Relative Affective Control for Zero-Shot Emotional Voice Conversion

Zihan Zhang, Shreeram Suresh Chandra, Zongyang Du +5

Traditional emotional voice conversion (EVC) conditions generation on explicit target emotions like labels or references, defining the target affective state but omitting the direc…

DiffAnon: Diffusion-based Prosody Control for Voice Anonymization

Ismail Rasim Ulgen, Zexin Cai, Nicholas Andrews +2

To preserve or not to preserve prosody is a central question in voice anonymization. Prosody conveys meaning and affect, yet is tightly coupled with speaker identity. Existing meth…

Neuron-Level Emotion Control in Speech-Generative Large Audio-Language Models

Xiutian Zhao, Ismail Rasim Ulgen, Philipp Koehn +2

Large audio-language models (LALMs) can produce expressive speech, yet reliable emotion control remains elusive: conversions often miss the target affect and may degrade linguistic…

Process-Supervised Reinforcement Learning for Interactive Multimodal Tool-Use Agents

Weiting Tan, Xinghua Qu, Ming Tu +4

Effective interactive tool use requires agents to master Tool Integrated Reasoning (TIR): a complex process involving multi-turn planning and long-context dialogue management. To t…
