CultureConverse: A Multilingual Multi-turn Simulation Harness for Culturally Grounded Assistance in East and Southeast Asia

Bryan Chen Zhengyu Tan, Weihua Zheng, Thong T. Doan +30

Current cultural evaluations for large language models (LLMs) often reduce culture to single-turn factual recall via MCQs, failing to capture a common use case: users seeking pract…

MemUse: Moving Memory Evaluation from Direct QA to Natural Integration in Long-Term Human-AI Conversation

Ryuichi Sumida, Koji Inoue, Tatsuya Kawahara

Memory systems for conversational LLMs are conventionally evaluated by direct, fact-seeking questions about prior dialogue (Direct QA): can the model recall fact X from a prior con…

Does Listening Matter? Backchanneling and Nodding in AI Clone

Koji Inoue, Kazushi Kato, Tatsuya Kawahara +1

AI clones that imitate a specific person typically reproduce what the person says and how they sound, but not how they listen. We investigate whether adding multimodal listening be…

Real-time Generation of Listener Nodding via Prediction of Kinematic Parameters for Avatar Dialogue Systems

Kazushi Kato, Koji Inoue, Taiga Mori +2

In human dialogue, we achieve smooth communication by expressing nonverbal cues such as eye contact, nodding, and facial expressions with precise timing. It is expected for convers…

Low-Latency Turn-Taking via Context-Aware Preface Generation in a Real-World Dialogue Robot

Yuki Okafuji, Koji Inoue, Yoshiki Ohira

Large language model (LLM)-based dialogue systems suffer response delays because generation begins only after final speech recognition. While fixed fillers are a workaround, they b…

On the Structure of Address in Multi-Party Dialogue: From Discrete Labels to Continuous Levels

Taiga Mori, Koji Inoue, Divesh Lala +1

In multi-party dialogues between a dialogue system and multiple users, identifying to whom an utterance is addressed is a key challenge. Prior work has typically treated addressee…

Memory-Driven Self-Disclosure and Relational Turning Points: A Longitudinal Multimodal Study of Human-AI Interaction

Ryuichi Sumida, Mao Saeki, Masaki Eguchi +4

As conversational AI systems are designed for repeated use, a central question is how a series of interactions becomes a relationship. We present a longitudinal multimodal study of…

I Understand How You Feel: Enhancing Deeper Emotional Support Through Multilingual Emotional Validation in Dialogue System

Zi Haur Pang, Yahui Fu, Koji Inoue +1

Emotional validation - explicitly acknowledging that a user's feelings make sense - has proven therapeutic value but has received little computational attention. Emotional validati…

Toward Signing Activity Projection in Sign Language Interaction

Takao Obi, Wang Yusong, Koji Inoue +1

Social robots must interact robustly not only with users assumed by speech-centered systems but also with diverse users whose communication relies on different modalities, e.g., si…

Emotion Transcription in Conversation: A Benchmark for Capturing Subtle and Complex Emotional States through Natural Language

Yoshiki Tanaka, Ryuichi Uehara, Koji Inoue +1

Emotion Recognition in Conversation (ERC) is critical for enabling natural human-machine interactions. However, existing methods predominantly employ categorical or dimensional emo…

Multilingual and Continuous Backchannel Prediction: A Cross-lingual Study

Koji Inoue, Mikey Elmers, Yahui Fu +5

We present a multilingual, continuous backchannel prediction model for Japanese, English, and Chinese, and use it to investigate cross-linguistic timing behavior. The model is Tran…

MMA-ASIA: A Multilingual and Multimodal Alignment Framework for Culturally-Grounded Evaluation

Weihua Zheng, Zhengyuan Liu, Tanmoy Chakraborty +32

Large language models (LLMs) are now used worldwide, yet their multimodal understanding and reasoning often degrade outside Western, high-resource settings. We propose MMA-ASIA, a…
