The current Transformer architecture is not well-suited for SER because its large parameter number demands significant computational resources, making it less feasible in environments with limited resources. Furthermore, its application to SER is limited because human emotions, which are expressed in long segments of continuous speech, are inherently complex and ambiguous. Therefore, designing specialized Transformer models tailored for SER is essential. To address these challenges, we propose a novel knowledge distillation framework that combines meta-knowledge and curriculum-based distillation. Specifically, we fine-tune the teacher model to optimize it for the SER task. For the student model, we embed individual sequence time points into variable tokens, which are used to aggregate the global speech representation. Additionally, we combine supervised contrastive and cross-entropy loss to increase the inter-class distance between learnable features. Finally, we optimize the student model using both meta-knowledge and the curriculum-based distillation framework. Experimental results on two benchmark datasets, IEMOCAP and MELD, demonstrate that our method performs competitively with state-of-the-art approaches in SER.","PeriodicalId":13131,"journal":{"name":"IEEE Transactions on Affective Computing","volume":"16 3","pages":"1307-1317"},"PeriodicalIF":9.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
