-## Overview
+# LEMAS-TTS
+
+LEMAS-TTS is a multilingual zero-shot text-to-speech 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).
 
-LEMAS‑TTS is a multilingual zero‑shot text‑to‑speech system, supporting 10 languages:

+## Model Description
 
-You can try the model via our Hugging Face demo: [https://huggingface.co/spaces/LEMAS-Project/LEMAS-TTS](https://huggingface.co/spaces/LEMAS-Project/LEMAS-TTS)
+LEMAS-TTS is built upon a non-autoregressive flow-matching framework. It leverages the massive scale and linguistic diversity of the LEMAS-Dataset to achieve robust zero-shot multilingual synthesis. The model incorporates accent-adversarial training and CTC loss to mitigate cross-lingual accent issues, enhancing synthesis stability and quality across diverse languages.
 
-For more details, please visit our GitHub repository: ([https://github.com/LEMAS-Project/LEMAS-TTS](https://github.com/LEMAS-Project/LEMAS-TTS))
+## Supported Languages
 
+The model supports 10 major languages for zero-shot synthesis:
+- Chinese (zh)
+- English (en)
+- Spanish (es)
+- Russian (ru)
+- French (fr)
+- German (de)
+- Italian (it)
+- Portuguese (pt)
+- Indonesian (id)
+- Vietnamese (vi)
+
+## Training Data
+
+LEMAS-TTS was trained on the [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.
