DIFFA: Large Language Diffusion Models Can Listen and Understand

AAAI 2026technical

Recent advances in large language models (LLMs) have shown remarkable capabilities across textual and multimodal domains. In parallel, large language diffusion models have emerged as a promising alternative to the autoregressive paradigm, offering improved controllability, bidirectional context mode

ChildMandarin: A Comprehensive Mandarin Speech Dataset for Young Children Aged 3-5

ACL 2025long

Automatic speech recognition (ASR) systems have advanced significantly with models like Whisper, Conformer, and self-supervised frameworks such as Wav2vec 2.0 and HuBERT. However, developing robust ASR models for young children’s speech remains challenging due to differences in pronunciation, tone,…

EPO: Explicit Policy Optimization for Strategic Reasoning in LLMs via Reinforcement Learning

ACL 2025long

Large Language Models (LLMs) have shown impressive reasoning capabilities in well-defined problems with clear solutions, such as mathematics and coding. However, they still struggle with complex real-world scenarios like business negotiations, which require strategic reasoning—an ability to navigate…

Enhancing Emotion Recognition in Incomplete Data: A Novel Cross-Modal Alignment, Reconstruction, and Refinement Framework

ICASSP 2025accepted

Multimodal emotion recognition systems rely heavily on the full availability of modalities, suffering significant performance declines when modal data is incomplete. To tackle this issue, we present the Cross-Modal Alignment, Reconstruction, and Refinement (CM-ARR) framework, an innovative approach…

M2R-Whisper: Multi-stage and Multi-scale Retrieval Augmentation for Enhancing Whisper

ICASSP 2025accepted

State-of-the-art models like OpenAI’s Whisper exhibit strong performance in multilingual automatic speech recognition (ASR), but they still face challenges in accurately recognizing diverse subdialects. In this paper, we propose M2R-Whisper, a novel multi-stage and multi-scale retrieval augmentation…

SDPO: Segment-Level Direct Preference Optimization for Social Agents

ACL 2025long

Social agents powered by large language models (LLMs) can simulate human social behaviors but fall short in handling complex social dialogues. Direct Preference Optimization (DPO) has proven effective in aligning LLM behavior with human preferences across various agent tasks. However, standard DPO f…

Better Zero-Shot Reasoning with Role-Play Prompting

NAACL 2024long

Modern large language models (LLMs) exhibit a remarkable capacity for role-playing, enabling them to embody not only human characters but also non-human entities. This versatility allows them to simulate complex human-like interactions and behaviors within various contexts, as well as to emulate spe…

PromptRank: Unsupervised Keyphrase Extraction Using Prompt

ACL 2023long

The keyphrase extraction task refers to the automatic selection of phrases from a given document to summarize its core content. State-of-the-art (SOTA) performance has recently been achieved by embedding-based algorithms, which rank candidates according to how similar their embeddings are to documen…
