Many existing works on voice conversion (VC) tasks use automatic speech
recognition (ASR) models for ensuring linguistic consistency between source and
converted samples. However, for the low-data resource domains, training a
high-quality ASR remains to be a challenging task. In this work, we propose a
novel iterative way of improving both the ASR and VC models. We first train an
ASR model which is used to ensure content preservation while training a VC
model. In the next iteration, the VC model is used as a data augmentation
method to further fine-tune the ASR model and generalize it to diverse
speakers. By iteratively leveraging the improved ASR model to train VC model
and vice-versa, we experimentally show improvement in both the models. Our
proposed framework outperforms the ASR and one-shot VC baseline models on
English singing and Hindi speech domains in subjective and objective
evaluations in low-data resource settings.

本论文中，我们提出了一种新颖的迭代方法，用于同时提高自动语音识别模型和语音转换模型。我们在低数据资源情况下，通过使用语音转换模型作为数据增强方法来进一步微调 ASR 模型，从而实验性地展示了两个模型的性能提高。
