CS3-BENCH: EVALUATING AND ENHANCING SPEECH-TO-SPEECH LLMS FOR MANDARIN-ENGLISH CODE-SWITCHING

ICASSP 2026poster

The advancement of multimodal large language models has accelerated the development of speech-to-speech interaction systems. While natural monolingual interaction has been achieved, we find existing models exhibit deficiencies in language alignment. In our proposed Code-Switching Speech-to-Speech Be…

VocalNet: Speech LLMs with Multi-Token Prediction for Faster and High-Quality Generation

EMNLP 2025

Speech large language models (LLMs) have emerged as a prominent research focus in speech processing. In this work, we introduce VocalNet, a series of high-performance speech LLMs featuring a scalable and model-agnostic training framework as well as a novel multi-token prediction (MTP) paradigm for s

M3AV: A Multimodal, Multigenre, and Multipurpose Audio-Visual Academic Lecture Dataset

ACL 2024long

Publishing open-source academic video recordings is an emergent and prevalent approach to sharing knowledge online. Such videos carry rich multimodal information including speech, the facial and body movements of the speakers, as well as the texts and pictures in the slides and possibly even the pap…

MM-SAP: A Comprehensive Benchmark for Assessing Self-Awareness of Multimodal Large Language Models in Perception

ACL 2024long

Recent advancements in Multimodal Large Language Models (MLLMs) have demonstrated exceptional capabilities in visual perception and understanding. However, these models also suffer from hallucinations, which limit their reliability as AI systems. We believe that these hallucinations are partially du…

Post-decoder Biasing for End-to-End Speech Recognition of Multi-turn Medical Interview

COLING 2024main

End-to-end (E2E) approach is gradually replacing hybrid models for automatic speech recognition (ASR) tasks. However, the optimization of E2E models lacks an intuitive method for handling decoding shifts, especially in scenarios with a large number of domain-specific rare words that hold specific im…
