<p> This paper aims to build a Mutli-speaker, Multi-emotion, Multi-style, Multilingual (M4) TTS. We address this challenging task with a <i>semi-supervised contrastive learning</i>-based TTS framework. To effectively capture and disentangle speaker, style and emotion representations, contrastive learning from different levels, i.e. <i>utterance</i> and <i>category</i> level, is leveraged to extract the desired representations from speech. Furthermore, a semi-supervised training strategy is introduced to improve the data utilization efficiency by involving multi-domain data, including style-labeled data, emotion-labeled data, and abundant unlabeled data.
To achieve expressive speech with diverse styles and emotions for a target speaker, the learned disentangled representations are integrated into an improved VITS model. Experiments on monolingual and multilingual corpora demonstrate the effectiveness of the proposed method.
