Emotional Voice Conversion aims to manipulate a speech according to a given
emotion while preserving non-emotion components. Existing approaches cannot
well express fine-grained emotional attributes. In this paper, we propose an
Attention-based Interactive diseNtangling Network (AINN) that leverages
instance-wise emotional knowledge for voice conversion. We introduce a
two-stage pipeline to effectively train our network: Stage I utilizes
inter-speech contrastive learning to model fine-grained emotion and
intra-speech disentanglement learning to better separate emotion and content.
In Stage II, we propose to regularize the conversion with a multi-view
consistency mechanism. This technique helps us transfer fine-grained emotion
and maintain speech content. Extensive experiments show that our AINN
outperforms state-of-the-arts in both objective and subjective metrics.

提出了一种基于注意力的交互式解耦网络（AINN）来实现情感语音转换，该网络利用实例级情感知识进行训练，通过两个阶段的设计有效地模拟情感细节，并通过多视图一致性机制规范转换过程，从而优于现有的情感语音转换研究。
