MaskGCT is an innovative zero-shot text-to-speech (TTS) model that addresses the challenges present in autoregressive and non-autoregressive systems by eliminating the need for explicit alignment information and phone-level duration prediction. MaskGCT employs a two-stage model: the first stage uses text to predict semantic tokens extracted from a speech self-supervised learning (SSL) model; in the second stage, the model predicts acoustic tokens based on these semantic tokens. It follows a masking and prediction learning paradigm, learning to predict masked semantic or acoustic tokens based on given conditions and prompts during training. During inference, the model generates a specified length of tokens in parallel. Experiments show that MaskGCT surpasses the current state-of-the-art zero-shot TTS systems in terms of quality, similarity, and intelligibility.

StyleTTS 2 is a text-to-speech (TTS) model that utilizes large speech language models (SLMs) for style diffusion and adversarial training, achieving human-level TTS synthesis. It employs a diffusion model to model style as a latent stochastic variable, generating the most appropriate style for the given text without relying on voice references. Furthermore, we utilize large pre-trained SLMs (such as WavLM) as discriminators and incorporate our innovative differentiable duration modeling for end-to-end training, enhancing the naturalness of the synthesized speech. StyleTTS 2 surpasses human recordings on the single-speaker LJSpeech dataset and matches them on the multi-speaker VCTK dataset, garnering recognition from native English-speaking evaluators. Additionally, when trained on the LibriTTS dataset, our model outperforms prior publicly available zero-shot extension models. By demonstrating the potential of style diffusion and adversarial training with large SLMs, this work achieves human-level TTS synthesis on both single and multi-speaker datasets.
