+# 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
+
+<!-- audio-compress:table:start -->
+| config | split | format | settings | sample rate | rows | audio hours | size (orig → new) |
+|---|---|---|---|---|---:|---:|---|
+| `default` | `train` | Opus | level=0.9 | original | ? | ? | ? |
+<!-- audio-compress:table:end -->
+
+## 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).
