Boundary-Gate Collaborative Enhancement GeoVis-GNN for Joint Segmentation and Label Recognition of Video Human-Object Interactions

This paper proposes BGCE-GeoVis-GNN, a novel framework that enhances the stability of joint video human-object interaction segmentation and recognition by introducing an auxiliary boundary module and collaborative constraints to mitigate boundary shifts and label discontinuities caused by weak transitions, achieving significant performance improvements on MPHOI-72 and CAD-120 datasets.

ViTone: A Diagnostic Benchmark for Tonal Faithfulness in Vietnamese Text-to-Speech

This paper introduces ViTone, a diagnostic benchmark and pre-registered evaluation protocol designed to directly assess tonal faithfulness in Vietnamese text-to-speech systems by combining minimal-pair stimuli, an ASR-calibrated Tone Error Rate, and cue-level analysis of F0 and laryngealisation, addressing the limitations of existing metrics that fail to capture the language's contrastive tonal distinctions.
