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

LEMAS is a large-scale extensible multilingual audio suite, providing the largest open-source multilingual speech corpus with word-level timestamps to our knowledge, covering over 150,000 hours across 10 major languages. Built with a rigorous alignment and confidence-based filtering pipeline, LEMAS supports diverse generative paradigms including zero-shot multilingual synthesis (LEMAS-TTS) and seamless speech editing (LEMAS-Edit).
