Abstract：Advancements inartificialinteligence have madedistinguishingsynthesized speech fromgenuinespeech increasinglychallenging，complicating audio deepfake detection.Existing methods often exhibit low acuracy，poor generalization， and weakrobustness.Thisstudy proposed MFF-STViT，amethod integratingthreeaudio features with vocoderartifactfeatures through anovelfeature fusionmoduletoenhance representation.The fused features were processdusing animproved Transformer model，STViT，toreduce redundancyand improve detectionperformance.Onthe ASVspoof2019LA testset，the method reduced the equal error rate（EER）by 71.38% on average. On the ASVspoof2O21 LA dataset， it achieved average reductions of 44.41% in EERand 18.11% intheminimum tandem detection cost function（min-tDCF）.For the ASVspoof2021 DF dataset， the average EER decreased by 57.81% ，with reductions exceeding 80% in specific partitions. These findings demonstrate the efectiveness of MFF-STViT in improving accuracy，generalization，and robustness.
