The Transformer-CME module uses cross-modal Transformer architecture to fuse speech prosody, facial micro-expressions, and body language, constructing culture-agnostic emotional representations by filtering cultural noise. The Cultural Adaptive Augmentation Engine (CAAE) employs conditional generative adversarial networks to generate synthetic samples for underrepresented cultures, while a discriminator enhances sensitivity to cultural expression differences. The MAML module optimizes model initialization via meta-training, enabling rapid adaptation to new cultural scenarios with minimal target data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Experiments on CMU-MOSEI, MELD, and CREMA-D show MetaEmo achieves F1-scores of 87.9%, 86.3%, and 84.7%, outperforming the best baseline by 2.9%\u20133.4%. It reduces cross-racial accuracy variance to 8.4% and cuts training time by 60% compared to traditional models, verifying efficiency and cultural robustness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>MetaEmo effectively addresses cultural differences and data scarcity but has limitations in minority culture coverage.
