Muyan-TTS is a trainable TTS model designed for podcast applications within a $50,000 budget, which is pre-trained on over 100,000 hours of podcast audio data, enabling zero-shot TTS synthesis with high-quality voice generation. Furthermore, Muyan-TTS supports speaker adaptation with dozens of minutes of target speech, making it highly customizable for individual voices.

## Install
### Clone & Install
```sh
git clone https://github.com/MYZY-AI/Muyan-TTS.git
cd Muyan-TTS

conda create -n muyan-tts python=3.10 -y
conda activate muyan-tts
make build
```

You need to install ```FFmpeg```. If you're using Ubuntu, you can install it with the following command:
```sh
sudo apt update
sudo apt install ffmpeg
```



Additionally, you need to download the weights of [chinese-hubert-base](https://huggingface.co/TencentGameMate/chinese-hubert-base).

Place all the downloaded models in the ```pretrained_models``` directory. Your directory structure should look similar to the following:
```
pretrained_models
├── chinese-hubert-base
├── Muyan-TTS
└── Muyan-TTS-SFT
```

## Quickstart
```sh
python tts.py
```
This will synthesize speech through inference. The core code is as follows:
```py
async def main(model_type, model_path):
    tts = Inference(model_type, model_path, enable_vllm_acc=False)
    wavs = await tts.generate(
        ref_wav_path="assets/Claire.wav",
        prompt_text="Although the campaign was not a complete success, it did provide Napoleon with valuable experience and prestige.",
        text="Welcome to the captivating world of podcasts, let's embark on this exciting journey together."
    )
    output_path = "logs/tts.wav"
    with open(output_path, "wb") as f:
        f.write(next(wavs))  
    print(f"Speech generated in {output_path}")
```
You need to specify the prompt speech, including the ```ref_wav_path``` and its ```prompt_text```, and the ```text``` to be synthesized. The synthesized speech is saved by default to ```logs/tts.wav```.

Additionally, you need to specify ```model_type``` as either ```base``` or ```sft```, with the default being ```base```.

When you specify the ```model_type``` to be ```base```, you can change the prompt speech to arbitrary speaker for zero-shot TTS synthesis.

When you specify the ```model_type``` to be ```sft```, you need to keep the prompt speech unchanged because the ```sft``` model is trained on Claire's voice.

## API Usage
```sh
python api.py
```
Using the API mode automatically enables vLLM acceleration, and the above command will start a service on the default port ```8020```. Additionally, LLM logs will be saved in ```logs/llm.log```.

You can send a request to the API using the example below:
```py
import time
import requests
TTS_PORT=8020
payload = {
    "ref_wav_path": "assets/Claire.wav",
    "prompt_text": "Although the campaign was not a complete success, it did provide Napoleon with valuable experience and prestige.",
    "text": "Welcome to the captivating world of podcasts, let's embark on this exciting journey together."
}
start = time.time()

url = f"http://localhost:{TTS_PORT}/get_tts"
response = requests.post(url, json=payload)
audio_file_path = "logs/tts.wav"
with open(audio_file_path, "wb") as f:
    f.write(response.content)
    
print(time.time() - start)
```

By default, the synthesized speech will be saved at ```logs/tts.wav```.

Similarly, you need to specify ```model_type``` as either ```base``` or ```sft```, with the default being ```base```.

## Training

We use ```LibriSpeech``` as an example. You can use your own dataset instead, but you need to organize the data into the format shown in ```data_process/examples```.

If you haven't downloaded ```LibriSpeech``` yet, you can download the dev-clean set using:
```sh
wget --no-check-certificate https://www.openslr.org/resources/12/dev-clean.tar.gz
```
After uncompressing the data, specify the ```librispeech_dir``` in ```prepare_sft_dataset.py``` to match the download location. Then run:
```sh
./train.sh
```
This will automatically process the data and generate ```data/tts_sft_data.json```.

Note that we use a specific speaker ID of "3752" from dev-clean of LibriSpeech (which can be specified in ```data_process/text_format_conversion.py```) as an example because its data size is relatively large. If you organize your own dataset for training, please prepare at least a dozen of minutes of speech from the target speaker.

If an error occurs during the process, resolve the error, delete the existing contents of the data folder, and then rerun ```train.sh```.

After generating ```data/tts_sft_data.json```, train.sh will automatically copy it to ```llama-factory/data``` and add the following field to ```dataset_info.json```:
```json
"tts_sft_data": {
    "file_name": "tts_sft_data.json"
}
```
Finally, it will automatically execute the ```llamafactory-cli train``` command to start training. You can adjust training settings using ```training/sft.yaml```.

By default, the trained weights will be saved to ```pretrained_models/Muyan-TTS-new-SFT```.

After training, you need to copy the ```sovits.pth``` of base/sft model to your trained model path before inference:
```sh
cp pretrained_models/Muyan-TTS/sovits.pth pretrained_models/Muyan-TTS-new-SFT
```

You can directly deploy your trained model using the API tool above. During inference, you need to specify the ```model_type``` to be ```sft``` and replace the ```ref_wav_path``` and ```prompt_text``` with a sample of the speaker's voice you trained on.
