Table 2 Objective evaluation results of the ablation study on architecture in seen-to-seen conversion scenario. “AGAIN-VC” represents the network has neither U2-Net structure nor SaAdaIN. “U2-VC” represents the network has both U2-Net structure and SaAdaIN
From: U2-VC: one-shot voice conversion using two-level nested U-structure
