We then devise training strategies to achieve EVC for Unseen Speaker-Emotion Pairs (i.e., EVC-USEP) by using emotional data from supporting speakers. To achieve this, we propose a Virtual Domain Pairing (VDP) training strategy, which randomly generates the combinations of speaker-emotion pairs that are not present in the real data without compromising the min-max game of a discriminator and generator in adversarial training. In particular, a fake-pair masking (FPM) strategy is proposed to ensure that the discriminator does not overfit because of the fake pairs.
