# SeedTTS Evaluation Dataset

This dataset contains evaluation data for SeedTTS text-to-speech model testing in multiple languages.

Original repo from: [https://github.com/BytedanceSpeech/seed-tts-eval](https://github.com/BytedanceSpeech/seed-tts-eval)

---

## Languages

* **English (en)**: Contains `test_wer` and `test_sim` splits
* **Chinese (zh)**: Contains `test_wer`, `test_sim`, and `test_wer_hardcase` splits

---

## Usage

```python

# makesure: pip install datasets==3.5.1

import os
from datasets import load_dataset

repo_dir = "hhqx/seedtts_testset"

ds_en = load_dataset(repo_dir, 'en', trust_remote_code=True)
print(ds_en['test_wer'][0])

ds_zh = load_dataset(repo_dir, 'zh', trust_remote_code=True)
print(ds_zh['test_sim'][0])


# Access specific splits
en_wer = ds_en['test_wer']
en_sim = ds_en['test_sim']

zh_wer = ds_zh['test_wer']
zh_sim = ds_zh['test_sim']
zh_hardcase = ds_zh['test_wer_hardcase']


for config, split in [
    ['en', 'test_wer'],
    ['en', 'test_sim'],
    ['zh', 'test_wer'],
    ['zh', 'test_sim'],
    ['zh', 'test_wer_hardcase'],
]:
    data = load_dataset(repo_dir, config, trust_remote_code=True, split=split)
    for item in data:
        for key, value in item.items():
            if key in ['audio_ground_truth', 'prompt_audio', ] and value:
                assert os.path.exists(value), f'path not exist: {value}'
    print("len of {} {}: {}".format(config, split, len(data)))
```

## Notes

* The `.tgz` files contain the audio `.wav` files and will be automatically extracted to the local Hugging Face cache directory during dataset loading.
* To control where the data archive is extracted and cached, use the `cache_dir` argument in `load_dataset`, e.g.:

```python
ds = load_dataset("path/to/seedtts-dataset-repo", "en", cache_dir="/your/fast/storage/path")
```
