MaskGCT: Zero-Shot Text-to-Speech with Masked Generative Codec Transformer
Quickstart
Clone and install
git clone https://github.com/open-mmlab/Amphion.git
# create env
bash ./models/tts/maskgct/env.sh
Model download
We provide the following pretrained checkpoints:
| Model Name | Description |
|---|---|
| Acoustic Codec | Converting speech to semantic tokens. |
| Semantic Codec | Converting speech to acoustic tokens and reconstructing waveform from acoustic tokens. |
| MaskGCT-T2S | Predicting semantic tokens with text and prompt semantic tokens. |
| MaskGCT-S2A | Predicts acoustic tokens conditioned on semantic tokens. |
You can download all pretrained checkpoints from HuggingFace or use huggingface api.

Basic Usage
You can use the following code to generate speech from text and a prompt speech.
