**F5-TTS**: Diffusion Transformer with ConvNeXt V2, faster trained and inference.
**E2 TTS**: Flat-UNet Transformer, closest reproduction.
**Sway Sampling**: Inference-time flow step sampling strategy, greatly improves performance
## Installation
Clone the repository:
```bash
git clone https://github.com/SWivid/F5-TTS.git
cd F5-TTS
```
Install torch with your CUDA version, e.g. :
```bash
pip install torch==2.3.0+cu118 --extra-index-url https://download.pytorch.org/whl/cu118
pip install torchaudio==2.3.0+cu118 --extra-index-url https://download.pytorch.org/whl/cu118
```
Install other packages:
```bash
pip install -r requirements.txt
```
## Prepare Dataset
Example data processing scripts for Emilia and Wenetspeech4TTS, and you may tailor your own one along with a Dataset class in `model/dataset.py`.
```bash
# prepare custom dataset up to your need
# download corresponding dataset first, and fill in the path in scripts
# Prepare the Emilia dataset
python scripts/prepare_emilia.py
# Prepare the Wenetspeech4TTS dataset
python scripts/prepare_wenetspeech4tts.py
```
## Training
Once your datasets are prepared, you can start the training process.
```bash
# setup accelerate config, e.g. use multi-gpu ddp, fp16
# will be to: ~/.cache/huggingface/accelerate/default_config.yaml
accelerate config
accelerate launch train.py
```

## Inference
To run inference with pretrained models, download the checkpoints from [🤗 Hugging Face](https://huggingface.co/SWivid/F5-TTS), or automatically downloaded with `inference-cli` and `gradio_app`.
Currently support 30s for a single generation, which is the **TOTAL** length of prompt audio and the generated. Batch inference with chunks is supported by `inference-cli` and `gradio_app`.
- To avoid possible inference failures, make sure you have seen through the following instructions.
- A longer prompt audio allows shorter generated output. The part longer than 30s cannot be generated properly. Consider using a prompt audio <15s.
- Uppercased letters will be uttered letter by letter, so use lowercased letters for normal words.
- Add some spaces (blank: " ") or punctuations (e.g. "," ".") to explicitly introduce some pauses. If first few words skipped in code-switched generation (cuz different speed with different languages), this might help.
### CLI Inference
Either you can specify everything in `inference-cli.toml` or override with flags. Leave `--ref_text ""` will have ASR model transcribe the reference audio automatically (use extra GPU memory). If encounter network error, consider use local ckpt, just set `ckpt_path` in `inference-cli.py`
```bash
python inference-cli.py \
--model "F5-TTS" \
--ref_audio "tests/ref_audio/test_en_1_ref_short.wav" \
--ref_text "Some call me nature, others call me mother nature." \
--gen_text "I don't really care what you call me. I've been a silent spectator, watching species evolve, empires rise and fall. But always remember, I am mighty and enduring. Respect me and I'll nurture you; ignore me and you shall face the consequences."
python inference-cli.py \
--model "E2-TTS" \
--ref_audio "tests/ref_audio/test_zh_1_ref_short.wav" \
--ref_text "对,这就是我,万人敬仰的太乙真人。" \
--gen_text "突然,身边一阵笑声。我看着他们,意气风发地挺直了胸膛,甩了甩那稍显肉感的双臂,轻笑道,我身上的肉,是为了掩饰我爆棚的魅力,否则,岂不吓坏了你们呢?"
```
### Gradio App
Currently supported features:
- Chunk inference
- Podcast Generation
- Multiple Speech-Type Generation
You can launch a Gradio app (web interface) to launch a GUI for inference (will load ckpt from Huggingface, you may set `ckpt_path` to local file in `gradio_app.py`). Currently load ASR model, F5-TTS and E2 TTS all in once, thus use more GPU memory than `inference-cli`.
```bash
python gradio_app.py
```
You can specify the port/host:
```bash
python gradio_app.py --port 7860 --host 0.0.0.0
```
Or launch a share link:
```bash
python gradio_app.py --share
```
### Speech Editing
To test speech editing capabilities, use the following command.
```bash
python speech_edit.py
```
## Evaluation
### Prepare Test Datasets
1. Seed-TTS test set: Download from [seed-tts-eval](https://github.com/BytedanceSpeech/seed-tts-eval).
2. LibriSpeech test-clean: Download from [OpenSLR](http://www.openslr.org/12/).
3. Unzip the downloaded datasets and place them in the data/ directory.
4. Update the path for the test-clean data in `scripts/eval_infer_batch.py`
5. Our filtered LibriSpeech-PC 4-10s subset is already under data/ in this repo
### Batch Inference for Test Set
To run batch inference for evaluations, execute the following commands:
```bash
# batch inference for evaluations
accelerate config # if not set before
bash scripts/eval_infer_batch.sh
```
### Download Evaluation Model Checkpoints
1. Chinese ASR Model: [Paraformer-zh](https://huggingface.co/funasr/paraformer-zh)
2. English ASR Model: [Faster-Whisper](https://huggingface.co/Systran/faster-whisper-large-v3)
3. WavLM Model: Download from [Google Drive](https://drive.google.com/file/d/1-aE1NfzpRCLxA4GUxX9ITI3F9LlbtEGP/view).
### Objective Evaluation
**Some Notes**
For faster-whisper with CUDA 11:
```bash
pip install --force-reinstall ctranslate2==3.24.0
```
(Recommended) To avoid possible ASR failures, such as abnormal repetitions in output:
```bash
pip install faster-whisper==0.10.1
```
Update the path with your batch-inferenced results, and carry out WER / SIM evaluations:
```bash
# Evaluation for Seed-TTS test set
python scripts/eval_seedtts_testset.py
# Evaluation for LibriSpeech-PC test-clean (cross-sentence)
python scripts/eval_librispeech_test_clean.py
```
