Nhut Minh Nguyen, Thanh Trung Nguyen, Phuong-Nam Tran, Chee Peng Lim, Nhat Truong Pham and Duc Ngoc Minh Dang, “Multi-Modal Fusion in Speech Emotion Recognition: A Comprehensive Review of Methods and Technologies”: This review synthesizes a comprehensive collection of publications from 2020 to 2024, exploring prominent multimodal fusion strategies, including early fusion, late fusion, deep fusion, and hybrid fusion methods, while also examining data representation, data translation, attention mechanisms, and graph-based fusion technologies. We assess the effectiveness of various fusion techniques across standard SER datasets, highlighting their performance in diverse tasks and addressing challenges related to data alignment, noise management, and computational demands. Furthermore, we highlight real-world applications of multimodal SER and provide critical research challenges that must be addressed for practical deployment, offering insights into optimal fusion strategies and guiding future developments in multimodal SER.
