With the widespread adoption of interactive machine applications, Emotion Recognition in Conversations (ERC) technology has garnered increasing attention. Although existing methods have improved recognition accuracy by integrating structured data, language barriers and the scarcity of non-English resources limit their cross-lingual applications. In light of this, the MERC-PLTAF method proposed in this paper innovatively focuses on multimodal emotion recognition in conversations, aiming to overcome the limitations of single modality and language barriers through refined feature extraction and a sophisticated cross-fusion strategy. We conducted extensive validation on multiple English and Chinese datasets, and the experimental results demonstrate that this method not only significantly improves emotion recognition accuracy but also exhibits exceptional performance on the Chinese M3ED dataset, paving a new path for cross-lingual emotion recognition. This research not only advances the boundaries of emotion recognition technology but also lays a solid theoretical foundation and practical framework for creating more intelligent and human-centric interactive experiences.
