EM2LDL: A Multilingual Speech Corpus for Mixed Emotion Recognition through Label Distribution Learning

arXiv — cs.CLWednesday, November 26, 2025 at 5:00:00 AM
  • The introduction of EM2LDL marks a significant advancement in the field of affective computing, presenting a multilingual speech corpus aimed at enhancing mixed emotion recognition through label distribution learning. This corpus includes expressive utterances in English, Mandarin, and Cantonese, reflecting the linguistic diversity and code-switching typical in regions like Hong Kong and Macao.
  • This development is crucial as it addresses the limitations of existing emotion corpora, which often lack linguistic variety and ecological validity. By integrating spontaneous emotional expressions and fine-grained emotion distributions, EM2LDL enhances the potential for more accurate emotion recognition systems across diverse languages and cultures.
  • The emergence of EM2LDL aligns with broader trends in artificial intelligence, particularly in the integration of multilingual capabilities and the exploration of emotional nuances in communication. This reflects a growing recognition of the importance of linguistic diversity in AI applications, as seen in recent studies focusing on unified frameworks for speech and music generation, as well as advancements in facial expression recognition and sentiment analysis.

STAGE: A Benchmark for Knowledge Graph Construction, Question Answering, and In-Script Role-Playing over Movie Screenplays
NeutralArtificial Intelligence
The introduction of STAGE (Screenplay Text, Agents, Graphs and Evaluation) marks a significant advancement in the field of narrative understanding, providing a comprehensive benchmark for evaluating knowledge graph construction, scene-level event summarization, long-context screenplay question answering, and in-script character role-playing across 150 films in English and Chinese.
It's All About the Confidence: An Unsupervised Approach for Multilingual Historical Entity Linking using Large Language Models
PositiveArtificial Intelligence
A new approach called MHEL-LLaMo has been introduced for multilingual historical entity linking, utilizing a combination of a Small Language Model (SLM) and a Large Language Model (LLM). This unsupervised ensemble method addresses challenges in processing historical texts, such as linguistic variation and noisy inputs, by leveraging a multilingual bi-encoder for candidate retrieval and an instruction-tuned LLM for predictions.
Get away with less: Need of source side data curation to build parallel corpus for low resource Machine Translation
PositiveArtificial Intelligence
A recent study emphasizes the importance of data curation in machine translation, particularly for low-resource languages.

Analyzing Bias in False Refusal Behavior of Large Language Models for Hate Speech Detoxification
NeutralArtificial Intelligence
A recent study analyzed the false refusal behavior of large language models (LLMs) in the context of hate speech detoxification, revealing that these models disproportionately refuse tasks involving higher semantic toxicity and specific target groups, particularly in English datasets.
VocalBench: Benchmarking the Vocal Conversational Abilities for Speech Interaction Models
NeutralArtificial Intelligence
VocalBench has been introduced as a benchmarking tool to evaluate the conversational abilities of speech interaction models, utilizing approximately 24,000 curated instances in English and Mandarin across four dimensions: semantic quality, acoustic performance, conversational abilities, and robustness. This initiative aims to address the shortcomings of existing evaluations that fail to replicate real-world scenarios and provide comprehensive comparisons of model capabilities.
