论文摘要
在许多情况下，非平行的多域语音转换方法（例如Stargan-VC）已被广泛应用。但是，这些模型的培训通常由于其复杂的对抗网络体系结构而构成挑战。为了解决这个问题，在这项工作中，我们利用最先进的对比学习技术，并将有效的暹罗网络结构纳入Stargan歧视者。我们的方法称为simsiam-Stargan-VC，它提高了训练稳定性，并有效地防止了训练过程中的歧视者过度拟合问题。我们对语音转换挑战（VCC 2018）数据集进行了实验，以及用户研究以验证框架的性能。我们的实验结果表明，Simsiam-Stargan-VC在客观和主观指标方面都显着优于现有的Stargan-VC方法。
Nonparallel multi-domain voice conversion methods such as the StarGAN-VCs have been widely applied in many scenarios. However, the training of these models usually poses a challenge due to their complicated adversarial network architectures. To address this, in this work we leverage the state-of-the-art contrastive learning techniques and incorporate an efficient Siamese network structure into the StarGAN discriminator. Our method is called SimSiam-StarGAN-VC and it boosts the training stability and effectively prevents the discriminator overfitting issue in the training process. We conduct experiments on the Voice Conversion Challenge (VCC 2018) dataset, plus a user study to validate the performance of our framework. Our experimental results show that SimSiam-StarGAN-VC significantly outperforms existing StarGAN-VC methods in terms of both the objective and subjective metrics.
