- **Amphion (/æmˈfaɪən/) is a toolkit for Audio, Music, and Speech Generation.** Its purpose is to support reproducible research and help junior researchers and engineers get started in the field of audio, music, and speech generation research and development. Amphion offers a unique feature: **visualizations** of classic models or architectures. We believe that these visualizations are beneficial for junior researchers and engineers who wish to gain a better understanding of the model.

57
-
58
- - Ampion supports multiple content-based features from various pretrained models, including [WeNet](https://github.com/wenet-e2e/wenet), [Whisper](https://github.com/openai/whisper), and [ContentVec](https://github.com/auspicious3000/contentvec). Their specific roles in SVC has been investigated in our SLT 2024 paper. [![arXiv](https://img.shields.io/badge/arXiv-Paper-<COLOR>.svg)](https://arxiv.org/abs/2310.11160) [![code](https://img.shields.io/badge/README-Code-red)](egs/svc/MultipleContentsSVC)
59
- - Amphion implements several state-of-the-art model architectures, including diffusion-, transformer-, VAE- and flow-based models. The diffusion-based architecture uses [Bidirectional dilated CNN](https://openreview.net/pdf?id=a-xFK8Ymz5J) as a backend and supports several sampling algorithms such as [DDPM](https://arxiv.org/pdf/2006.11239.pdf), [DDIM](https://arxiv.org/pdf/2010.02502.pdf), and [PNDM](https://arxiv.org/pdf/2202.09778.pdf). Additionally, it supports single-step inference based on the [Consistency Model](https://openreview.net/pdf?id=FmqFfMTNnv).
60

+ ## Overview
 
9
 
10
+ MaskGCT (**Mask**ed **G**enerative **C**odec **T**ransformer) is *a fully non-autoregressive TTS model that eliminates the need for explicit alignment information between text and speech supervision, as well as phone-level duration prediction*. MaskGCT is a two-stage model: in the first stage, the model uses text to predict semantic tokens extracted from a speech self-supervised learning (SSL) model, and in the second stage, the model predicts acoustic tokens conditioned on these semantic tokens. MaskGCT follows the *mask-and-predict* learning paradigm. During training, MaskGCT learns to predict masked semantic or acoustic tokens based on given conditions and prompts. During inference, the model generates tokens of a specified length in a parallel manner. Experiments with 100K hours of in-the-wild speech demonstrate that MaskGCT outperforms the current state-of-the-art zero-shot TTS systems in terms of quality, similarity, and intelligibility. Audio samples are available at [demo page](https://maskgct.github.io/).

64
+ **Basic Usage**
65
+
66
+ You can use the following code to generate speech from text and a prompt speech (the code is also provided in [inference.py](./models/tts/maskgct/maskgct_inference.py)).
67
+
68
+ ```python
69
+ from models.tts.maskgct.maskgct_utils import *
70
+ from huggingface_hub import hf_hub_download

80
+ # 1. build semantic model (w2v-bert-2.0)
81
+ semantic_model, semantic_mean, semantic_std = build_semantic_model(device)
82
+ # 2. build semantic codec
83
+ semantic_codec = build_semantic_codec(cfg.model.semantic_codec, device)
84
+ # 3. build acoustic codec
85
+ codec_encoder, codec_decoder = build_acoustic_codec(cfg.model.acoustic_codec, device)
86
+ # 4. build t2s model
87
+ t2s_model = build_t2s_model(cfg.model.t2s_model, device)
88

108
+ save_path = "[YOUR SAVE PATH]"
109
+ prompt_text = " We do not break. We never give in. We never back down."
110
+ target_text = "In this paper, we introduce MaskGCT, a fully non-autoregressive TTS model that eliminates the need for explicit alignment information between text and speech supervision."
111
+ # Specify the target duration (in seconds). If target_len = None, we use a simple rule to predict the target duration.
112
+ target_len = 18
113
+
114
+ maskgct_inference_pipeline = MaskGCT_Inference_Pipeline(
115

133
+ **Jupyter Notebook**
134
+
135
+ We also provide a [jupyter notebook](./models/tts/maskgct/maskgct_demo.ipynb) to show more details of MaskGCT inference.
