It supports both English and Chinese languages. Our model is trained with 100,000+ hours composed of chinese and english. The open-source version on HuggingFace is a 40,000 hours pre trained model without SFT. 29 | 30 | For formal inquiries about model and roadmap, please contact us at open-source@2noise.com. You could join our QQ group: 808364215 for discussion. Adding github issues is always welcomed. 31 | 32 | --- 33 | ## Highlights 34 | 1. **Conversational TTS**: ChatTTS is optimized for dialogue-based tasks, enabling natural and expressive speech synthesis. It supports multiple speakers, facilitating interactive conversations. 35 | 2. **Fine-grained Control**: The model could predict and control fine-grained prosodic features, including laughter, pauses, and interjections. 36 | 3. **Better Prosody**: ChatTTS surpasses most of open-source TTS models in terms of prosody. We provide pretrained models to support further research and development. 37 | 38 | For the detailed description of the model, you can refer to [video on Bilibili](https://www.bilibili.com/video/BV1zn4y1o7iV) 39 | 40 | --- 41 | 42 | ## Disclaimer 43 | 44 | This repo is for academic purposes only.

The data obtained from publicly available sources, and the authors do not claim any ownership or copyright over the data. 45 | 46 | ChatTTS is a powerful text-to-speech system. However, it is very important to utilize this technology responsibly and ethically. To limit the use of ChatTTS, we added a small amount of high-frequency noise during the training of the 40,000-hour model, and compressed the audio quality as much as possible using MP3 format, to prevent malicious actors from potentially using it for criminal purposes. At the same time, we have internally trained a detection model and plan to open-source it in the future. 47 | 48 | 49 | --- 50 | ## Usage 51 | 52 |

(PR or new repo are welcomed.) 132 | 133 | ---- 134 | ## FAQ 135 | 136 | ##### How much VRAM do I need? How about infer speed? 137 | For a 30-second audio clip, at least 4GB of GPU memory is required. For the 4090D GPU, it can generate audio corresponding to approximately 7 semantic tokens per second. The Real-Time Factor (RTF) is around 0.65. 138 | 139 | ##### model stability is not good enough, with issues such as multi speakers or poor audio quality. 140 | 141 | This is a problem that typically occurs with autoregressive models(for bark and valle). It's generally difficult to avoid. One can try multiple samples to find a suitable result. 142 | 143 | ##### Besides laughter, can we control anything else? Can we control other emotions? 144 | 145 | In the current released model, the only token-level control units are [laugh], [uv_break], and [lbreak]. In future versions, we may open-source models with additional emotional control capabilities. 146 | 147 | --- 148 | ## Acknowledgements 149 | - [bark](https://github.com/suno-ai/bark), [XTTSv2](https://github.com/coqui-ai/TTS) and [valle](https://arxiv.org/abs/2301.02111) demostrate a remarkable TTS result by a autoregressive-style system. 150 | - [fish-speech](https://github.com/fishaudio/fish-speech) reveals capability of GVQ as audio tokenizer for LLM modeling. 151 | - [vocos](https://github.com/gemelo-ai/vocos) which is used as a pretrained vocoder. 152 | 153 | --- 154 | ## Special Appreciation 155 | - [wlu-audio lab](https://audio.westlake.edu.cn/) for early algorithm experiments. 156 | -------------------------------------------------------------------------------- /README_CN.md: -------------------------------------------------------------------------------- 1 | # ChatTTS 2 | [**English**](./README.md) | [**中文简体**](./README_CN.md) 3 | 4 | ChatTTS是专门为对话场景设计的文本转语音模型，例如LLM助手对话任务。它支持英文和中文两种语言。最大的模型使用了10万小时以上的中英文数据进行训练。在HuggingFace中开源的版本为4万小时训练且未SFT的版本. 5 | 6 | 如需就模型进行正式商业咨询，请发送邮件至 open-source@2noise.com。对于中文用户，您可以加入我们的QQ群：808364215 进行讨论。同时欢迎在GitHub上提出问题。如果遇到无法使用HuggingFace的情况,可以在[modelscope](https://www.modelscope.cn/models/pzc163/chatTTS)上进行下载. 7 | 8 | --- 9 | ## 亮点 10 | 1. **对话式 TTS**: ChatTTS针对对话式任务进行了优化，实现了自然流畅的语音合成，同时支持多说话人。 11 | 2. **细粒度控制**: 该模型能够预测和控制细粒度的韵律特征，包括笑声、停顿和插入词等。 12 | 3. **更好的韵律**: ChatTTS在韵律方面超越了大部分开源TTS模型。同时提供预训练模型，支持进一步的研究。 13 | 14 | 对于模型的具体介绍, 可以参考B站的[宣传视频](https://www.bilibili.com/video/BV1zn4y1o7iV) 15 | 16 | --- 17 | 18 | ## 免责声明 19 | 本文件中的信息仅供学术交流使用。其目的是用于教育和研究，不得用于任何商业或法律目的。作者不保证信息的准确性、完整性或可靠性。本文件中使用的信息和数据，仅用于学术研究目的。这些数据来自公开可用的来源，作者不对数据的所有权或版权提出任何主张。 20 | 21 | ChatTTS是一个强大的文本转语音系统。然而，负责任地和符合伦理地利用这项技术是非常重要的。为了限制ChatTTS的使用，我们在4w小时模型的训练过程中添加了少量额外的高频噪音，并用mp3格式尽可能压低了音质，以防不法分子用于潜在的犯罪可能。同时我们在内部训练了检测模型，并计划在未来开放。 22 | 23 | --- 24 | ## 用法 25 | 26 |
