# LEMAS-Edit
|
| 21 |
+
|
| 22 |
+
LEMAS-Edit is a multilingual zero-shot speech editing system, presented in the paper [LEMAS: A 150K-Hour Large-scale Extensible Multilingual Audio Suite with Generative Speech Models](https://huggingface.co/papers/2601.04233).

+
- Chinese (zh)
|
| 33 |
+
- English (en)
|
| 34 |
+
- Spanish (es)

## Training Data
|
| 41 |
+
|
| 42 |
+
LEMAS-Edit was trained on the subset of [LEMAS-Dataset](https://huggingface.co/datasets/LEMAS-Project/LEMAS-Dataset-train), which is, to our knowledge, currently the largest open-source multilingual speech corpus with word-level timestamps. It covers over 150,000 hours across 10 major languages.
