# LEMAS: A 150K-Hour Large-scale Extensible Multilingual Audio Suite with Generative Speech Models

[**LEMAS**](https://lemas-project.github.io/LEMAS-Project/) is a large-scale extensible multilingual audio suite, providing multilingual speech corpus (**LEMAS-Dataset**) with word-level timestamps, covering over **150,000 hours** across **10 major languages(zh/en/de/fr/es/pt/it/ru/id/vi)**. Built with a rigorous alignment and confidence-based filtering pipeline, LEMAS supports diverse generative paradigms including zero-shot multilingual synthesis (**LEMAS-TTS**)(0.3B) and seamless speech editing (**LEMAS-Edit**)(0.3B).
