New benchmark improves co-speech gesture generation evaluation

Researchers have developed a new benchmark for evaluating co-speech gesture generation, aiming to better align objective metrics with human perception and semantic appropriateness. The benchmark includes a new metric called Semantic Gesture Preservation (SGP), which measures how well semantic gestures from ground truth are maintained in generated gestures. A perceptual study with 101 participants revealed that SGP correlates selectively with speech-aware human judgments, unlike previous metrics like Semantic Score (SC). The findings emphasize the need to validate objective metrics against subjective evaluations for more accurate assessment of gesture generation models. AI

IMPACT Introduces a more reliable evaluation method for co-speech gesture generation models, potentially guiding future research and development in multimodal AI.
