| # LSVSC (compressed audio) | |
| > **This is a compressed version of [`doof-ferb/LSVSC`](https://huggingface.co/datasets/doof-ferb/LSVSC).** | |
| > Only the audio column(s) were re-encoded (see the table below) to reduce download size; | |
| > every other column, subset and split name is kept unchanged. | |
| **License:** same as the original dataset (`cc-by-4.0`). Please refer to the [original dataset card](https://huggingface.co/datasets/doof-ferb/LSVSC) for the full description, citation and terms of use. | |
| ## Compressed splits | |

| ## Usage | |
| ```python | |
| from datasets import load_dataset | |
| ds = load_dataset('giangndm/LSVSC-opus', 'default', split='train') | |
| ``` | |
| Lossy formats (Opus / MP3) are not bit-exact with the original audio. Encoded with [`soundfile`](https://github.com/bastibe/python-soundfile) (libsndfile). | |
