<h2 id="abstract">1. Abstract<a name="abstract"></a></h2>
<p> Cross-speaker emotion transfer is an effective way to produce expressive speech for neutral target speakers, which doesn't require emotional training data of target speakers. Since the emotion and timbre of the source speaker are heavily entangled, existing approaches often struggle to trade off the speaker similarity and the emotion expressions.
In this paper, we propose to disentangle the timbre and the emotion of speech through information perturbation to conduct cross-speaker emotion transfer, which effectively learns the emotion expressions of the source speaker and maintains the timbre of the target neutral speakers. Specifically, we perturb the timbre and emotion information (e.g., formant and pitch) of source speech separately to obtain and model the emotion- and timbre-independent signals, based on which the proposed model could further produce emotional speech in the timbre of target speakers. Experiment results demonstrate that the proposed approach significantly outperforms the baseline models in terms of naturalness and similarity, indicating the effectiveness of information perturbation for cross-speaker emotion transfer.

<p><b>Short summary:</b> When the target neutral speaker is male, the FS2-GST and FS2-VAE cannot produce correct timbre, although the genereted speech is emotional. Besides, FS2-BN sometimes also cannot generate male voice. The proposed model could successfully maintain the target timbre when generating emotional speech.</p>

<p><b>Short summary:</b> Given different speaker and emotion embedding during inference, the Speaker-mel gererator could provide emotionless speech with specific timbre, while the output of the Emotion-mel gererator contains the emotion variations with random or averaged timbre. Based on the two outputs, the final generated speech has specifec emotion expressions and timbre.</p>
